Chapter 1: Introducing the Client Agents
This section contains the following topics: Introduction (see page 9) Benefits of Using a Client Agent (see page 9) Supported Client Systems (see page 10)

Introduction
CA ARCserve Backup is a comprehensive storage solution for applications, databases, distributed servers, and file systems. It provides backup and restore capabilities for databases, business-critical applications, and network clients. Among the compatible agents CA ARCserve Backup offers are a specific set of operating-system-based client agents. The client agents are separate software packages installed on network computers to supply a network interface between the computer and CA ARCserve Backup. In addition to enabling connectivity, the client agents share data storage tasks with the backup servers in your network. You may need multiple client agents, depending on the number and variety of network machines that require regular data backup and restore functionality. This guide provides information on installing, configuring, and adding client agents for all workstations and servers in your network storage environment.

Benefits of Using a Client Agent
CA ARCserve Backup client agents are designed for organizations that need to preserve network resources by offloading tasks onto centralized backup servers and media. Among other functions, the client agents serve to: ■ ■ ■ ■ Minimize the load on your communications network Increase the efficiency of your CA ARCserve Backup servers by offloading the preprocessing of archive data to the client machine Supply detailed file and directory information about the remote client to the CA ARCserve Backup server Communicate with the server and let you browse and select backup components

Chapter 1: Introducing the Client Agents 9

Supported Client Systems

Chapter 1: Introducing the Client Agents 11

Chapter 2: Installing the Client Agents
To perform a backup or restore job, you must install and start the appropriate CA ARCserve Backup client agent software. The client agent provides communication between a workstation and the CA ARCserve Backup server. This chapter describes how to install client agents. This section contains the following topics: Installation Considerations (see page 13) Install the Client Agents (see page 15) Common Agent Automatic Installation (see page 15) Installation Directories for the Common Agent and Client Agents (see page 16)

Installation Considerations
The following sections include information you should review before installing the client agents.

Client Agent for Windows
Before installing the client agent for Windows, review the following considerations. ■ Before you can run the client agent for Windows, your computer must be configured to communicate using one or more of the following network protocols: – – Transmission Control Protocol/Internet Protocol (TCP/IP) Windows Socket (WinSock) Direct

Client Agent for NetWare
Before installing the client agent for NetWare, review the following considerations. ■ The client agent for NetWare can be installed on NetWare servers only. Also, to perform a NetWare installation, your local machine must be equipped with the Novell client for Windows. The NetWare server must be configured to communicate using TCP/IP.



Chapter 2: Installing the Client Agents 13

Installation Considerations



You must have supervisor rights on the eDirectory tree of the NetWare computer on which you are installing this client agent. For details, see your Novell NetWare documentation. For optimum performance, use the latest NetWare C library (CLIB) and Systems Management Server (SMS) modules. The NetWare Loadable Modules (NLMs) are available from Novell.

■ ■

Enterprise Option for OpenVMS
Before installing the enterprise option for OpenVMS, review the following considerations. ■ A computer running the supported Alpha and VAX operating systems can use either TCP or User Data Protocol (UDP) with any of the following communications software: – – – – – Compaq UCX 4.2 eco 3 (on Alpha) Compaq UCX 3.3 eco 13 (on VAX) Compaq TCP/IP Versions 5.0 through 5.3 Process Software Multinet Version 4.1B (with patches) through Version 4.4 Process Software TCPWARE Versions 5.3 and 5.4

Important! If necessary, you can install two or more of these communications packages on the same computer; however, you can run only one package at a time. Do not run two or more of these communications packages simultaneously on the same computer. Note: If you change OpenVMS TCP/IP stacks at any time, you must reinstall the OpenVMS Enterprise Option. ■ ■ You should back up your OpenVMS system disk before installing the OpenVMS Enterprise Option. Ensure that you have at least 10 blocks of free space for setup file .

Communication Requirements for Client Agents Installed on UNIX, Linux, and Mainframe Linux Platforms
To help ensure that CA ARCserve Backup primary servers and member servers can communicate with the CA ARCserve Backup agents that are installed on UNIX, Linux, and Mainframe Linux computers, you must allow CA ARCserve Backup to communicate with the agent through the firewall, if any, that is configured on the agent computers. You can allow CA ARCserve Backup to communicate with the agent computers by adding CA ARCserve Backup to the firewall exceptions list on the agent computers.

14 Client Agents Guide

Install the Client Agents

As a best practice, you should add CA ARCserve Backup to the firewall exceptions list on the agent computers before you install the agents. This requirement affects the following CA ARCserve Backup components: ■ ■ ■ ■ ■ ■ Client Agent for UNIX Client Agent for Linux Client Agent for Mainframe Linux Oracle Agent on UNIX platforms Oracle Agent on Linux platforms UNIX and Linux Data Mover

For information about how to configure the firewall on the agent computers, see the platform-specific documentation. Note: By default, CA ARCserve Backup communicates using port 6051.

16 Client Agents Guide

Chapter 3: Adding and Configuring the Client Agents
After installing CA ARCserve Backup and its various client agents, you must add and configure each client agent machine in your network to the backup server. This chapter discusses the procedures for adding and configuring client agents. This section contains the following topics: Adding Client Agents (see page 17) Windows Client Agent Configuration (see page 19) NetWare Client Agent Configuration (see page 33) UNIX, Linux, and Mac OS X Client Agent Configuration (see page 35) AS/400 Enterprise Option Configuration (see page 53) OpenVMS Enterprise Option Configuration (see page 55)

Adding Client Agents
If you have CA ARCserve Backup installed on a Windows server, you can add client agents from your network using the Add, Import, Export Node feature or you can add client agents manually. The following sections include information on each of these methods.

How to Add, Import, and Export Agents and Nodes
Setting up a job in an environment with many agents and nodes can be a time-consuming and tedious task. If you have multiple agents and nodes to back up, it may take time to add the agents and nodes to the Backup Manager one at a time. The Add, Import, and Export Agents and Add, Import, and Export Nodes features let you add multiple nodes and agents using the CA ARCserve Backup user interface, whether the nodes and agents will be backed up. Note: The Central Agent Admin also lets you add, import, or export agents and nodes.

Chapter 3: Adding and Configuring the Client Agents 17

Adding Client Agents

You can use the Add, Import, and Export Nodes feature to add multiple nodes and agents into the system in either of the following ways: Add multiple agents and nodes using the user interface 1. From the Backup Manager Source Tab or the Restore Manager Destination Tab, select a node. 2. Use the Add/Import/Export Nodes dialog to manually enter the names of all the nodes and agents or select the nodes from the left-pane list of nodes and agents detected by auto-discovery. 3. Specify a user name and password for the nodes. 4. Save the information in the CA ARCserve Backup database. 5. View the nodes and agents in the Backup Manager Source tree or the Central Agent Admin. Add multiple nodes and agents using a .csv and .txt file 1. From the Backup Manager Source Tab or the Restore Manager Destination Tab, select a node. 2. Use the Import function on the Add/Import/Export Nodes dialog and specify the name of the .csv or .txt file from the user interface. The node and agent names are imported from the .csv or .txt file and are added into the system. 3. Specify a user name and password for the nodes and agents. 4. View the nodes and agents in the Backup Manager Source tree.

Manually Add Client Agents
If Auto Discovery does not detect all client agents in your network for some reason or if you want to add a particular client agent, you can manually add a client agent to a Windows server or NetWare server using the Windows manager interface. To manually add a client agent, you must add each client agent machine to the Backup Manager.

18 Client Agents Guide

Windows Client Agent Configuration

To manually add client agents 1. Open the Backup Manager and click the Source tab. 2. Right-click the appropriate client agent object, such as Windows Systems. 3. Select Add Machine/Object. The Add Agent dialog appears.

4. Enter the name of the computer in the Host Name field. Note: If you are adding a NetWare Client Agent, you must use the Novell server name as the host name. 5. Select the protocol you want to use to connect to the computer: ■ TCP/IP--Select TCP/IP and, if you are adding a Windows client agent, select Use Computer Name Resolution. Computer name resolution lets the local Windows computer automatically detect the remote Windows machine's IP address when connecting for backup and restore operations. This is the recommended method and works even if you do not know the computer's IP address. Note: If the target Windows computer has a dynamic IP address, using computer name resolution is preferable. If you are not adding a Windows client agent, if computer name resolution fails because of various DNS server or network configuration issues, or the target computer has multiple IP addresses and you want to be certain that a specific address is used, ensure that Use Computer Name Resolution is not selected and enter an IP address. 6. Click Add. The client agent is added to the server.

Windows Client Agent Configuration
The following sections discuss the Windows client agent configuration options.

Chapter 3: Adding and Configuring the Client Agents 19

Windows Client Agent Configuration

Windows-Related Configuration Notes
General information pertaining to the configuration of the Windows client agent includes: ■ Restoring System State—The System State supports the Restore to Original Location option. Note: The System State also supports restoring to an alternate location, but it will not recreate an operational system since the files are placed in default directories created by the agent at the time of restore. ■ Shares Support—When the use agent option is selected, the client agent backs up shares selected from the Preferred Shares/Machines object in the Backup Manager by converting the share name to the real path. Note: On Windows platforms, the client agent does not restore shares or support shares as a destination except for administrative shares. ■ Restoration of the System Hive—The KeysNotToRestore feature is designed to protect sensitive system registry keys during a regular restore of the client agent system hive. However, this feature is unavailable when you use the Client Agent Registry session to restore individual system keys.

Security Configuration Options
The Client Agent for Windows security options are defined on the Configuration dialog. Select one of the following types of security: System Security Lets you use Windows security to perform backup, compare, and restore operations. The client agent impersonates the active network user; that is, the client agent uses the user name and password to log on. This ID and password should identify a valid user in the local user database or in the domain database if the workstation is a member of a domain. Password Security Lets you set individual passwords for security. This setting enables the client agent to run under the local system account. Password Security is disabled by default. Note: If password security is selected, and DSA-based database agents (such as Sybase, Informix, and so on) are installed on the machine, whole node backup is not supported. To back up databases only, you must change the security information in the Security and Agent Information dialog, to the system security before submitting the job.

20 Client Agents Guide

Windows Client Agent Configuration

Backup Priority and Restore/Compare Priority Options
The Client Agent for Windows process priority is defined on the Configuration dialog. Select one of the following settings for Backup Priority and Restore/Compare Priority: High Foreground processing performs client agent functions before other processes. Normal Standard processing performs client agent functions without special status. Low Standard processing performs client agent functions when other processes are idle.

Multiple Concurrent Restore or Compare
The Client Agent for Windows simultaneous restore and compare is enabled on the Configuration dialog. Enable the Allow multiple simultaneous restore or compare jobs check box on the Configuration dialog if you want the Windows client agent to accept multiple concurrent restore or compare jobs.

Backup and Restore Execution Options
The Client Agent for Windows execution options are defined on the Configuration dialog. Select the pre-execution programs, post-execution programs, and define the execution delay. Pre-execution Enter or select the name of any batch programs (for example, C:\WINAGENT\PRE.CMD) that you want to automatically execute before the backup or restore operation. Post-execution Enter or select the name of any batch programs (for example, C:\WINAGENT\POST.CMD) that you want to automatically execute after the backup or restore operation. Execution Delay Select the number of seconds that you want the client agent to wait before or after executing the batch job.

22 Client Agents Guide

Windows Client Agent Configuration

You can define the following settings using the Configuration dialog: ■ Security Type Specification--Select one of the following types of security: System Security--Select this Security option to use Windows security to perform backup, compare, and restore operations. The client agent impersonates the active network user; that is, the client agent uses the user name and password to log on. This ID and password should identify a valid user in the local user database or in the domain database if the workstation is a member of a domain. Note: If you select System Security, Exchange Server 2010 database files are not backed up (that is, they are skipped) when you use the client agent to select partitions, folders or files for backup when the client agent backup account is a domain account with View Only Organization Management role or higher privileges. Exchanger Server 2010 database files are not skipped if you select Password Security, or if you use some other account role, such as local administrator or domain account without View-only Organization Management privileges. The system displays a warning when these database files are in use. Password Security--Select this Security option to set an individual password for security. This setting enables the client agent to run under the local system account. Password Security is disabled by default. ■ Setting Process Priority--These settings determine the priority given to the processes needed for the backup, restore, or compare operations. Select one of the following settings for Backup Priority and Restore/Compare Priority: High--Foreground processing performs client agent functions before other processes. Normal--Standard processing performs client agent functions without special status. Low--Standard processing performs client agent functions when other processes are idle. ■ Allow multiple simultaneous restore or compare jobs--Enable this if you want the Windows client agent to accept multiple concurrent restore or compare jobs. Note: By default, this option is disabled to ensure that new backup or restore jobs of the same data set are not accidentally launched during a running restore job. If this does occur, the agent denies the new job's request and reports that the client agent is busy to the CA ARCserve Backup server. ■ Enable physical disk/volume backup and restore--Lets you perform raw backups and restores on physical disks and volumes. Note: For more information, see the Administration Guide.

Chapter 3: Adding and Configuring the Client Agents 23

Windows Client Agent Configuration



Log--The Log file is stored in the following path: <ARCserve_HOME>\ARCserve Backup Client Agent for Windows\ntagent.log. The log for every job that runs is stored in this log file. Keep Log For--Specifies the number of days (the default is 60 days) to keep the agent log. After the specified number of days has elapsed the log will be deleted when the next agent backup, restore, or compare job runs.



Pre-Execution and Post-Execution Programs--Select the following execution options: Pre-execution--Enter or select the name of any batch programs (for example, C:\WINAGENT|PRE.CMD) that you want to automatically execute before the backup operation. Post-execution--Enter or select the name of any batch programs (for example, C:\WINAGENT|PRE.CMD) that you want to automatically execute after the backup operation. Execution Delay--Select the amount of seconds that you want the client agent to wait before or after the execution of the batch job.

3. Click OK to save your changes and exit the dialog. Note: To change your configuration later, you must return to the Configuration dialog.

Windows Client Agent Configuration

Configure Password Security
The client agent service uses the node (machine) user name and assigned password to log on to the CA ARCserve Backup network. To set password security for the client agent 1. Start the Backup Manager, and then right-click the machine name. A pop-up menu appears. 2. Choose Security from the pop-up menu to open the Security dialog. The User Name field should already contain the client agent’s assigned user name. 3. Enter the password for the client agent. Note: The user name and password should identify a valid user in the local machine’s database or in the domain database, if the workstation is a member of a domain. Also, when you specify the account to use, it may be necessary to distinguish between two accounts that use the same name (such as Administrator) by indicating where Windows can find each account. You can identify the client object’s location by using tree name formats when identifying the user name. For example, for a domain named NTDEV containing a workstation named ENGINEER, the respective administrators are:
NTDEV\Administrator ENGINEER\Administrator

View Configuration Selections
Before making changes to your configuration settings, you should verify your current configuration. To view your configuration selections 1. Open the Backup Agent Admin.

Configure Windows Network Communication
CA ARCserve Backup client agent services are shared across all configured client agents. By default, Windows client agents use TCP/UDP port 6050. You can change this behavior by using the Network Configuration menu in the Backup Agent Admin. To configure Windows network communication 1. Open the Backup Agent Admin. 2. From the Options menu, select Network Configuration:

Chapter 3: Adding and Configuring the Client Agents 27

Windows Client Agent Configuration

3. Using this dialog, set the following network parameters for the client agent: Specify Port Number Accept the defaults or enter the port values you want CA ARCserve Backup to use. If you want to use the original default port, click the Reset button. The updated port information will be saved in the local PortsConfig.cfg file located in \Program Files\CA\SharedComponents\ARCserve Backup. Note: Updated port information must be registered with the CA ARCserve Backup server component. To do this, you must modify the remote server PortsConfig.cfg file. For more information on port configuration, see the Implementation Guide. Select IP Address The Windows client agent supports the use of multiple network interface cards (NICs). For computers with more than one network card, the agent checks all enabled NICs in the machine. You can manually override this selection by choosing the IP address of the NIC that you want to dedicate for backup purposes. When you define this configuration, the client agent will listen using only this interface card. All other NICs are ignored and you will not be able to use their IP addresses to connect to the client agent. Any updated information also needs to be modified in the Windows CAPortConfig.cfg file and copied to the CA ARCserve Backup home directory. The following example shows a CAPortConfig.cfg file:
#Hostname IP address (optional) TCP port UDP port #myhost nnn.nnn.nnn.nnn 6050 6050 mymachine nnn.nnn.nnn.nn 7090 7085

If you selected password security when configuring the Windows client agent from the Backup Agent Admin, you must specify the same password in CA ARCserve Backup. To set a workstation password 1. From the Backup Manager, right-click the name of the client agent. 2. Choose Security from the pop-up menu.

3. Enter the local Windows user account name or enter the Windows domain account using the tree format. 4. Enter the password and click OK. Note: If you use a client agent to perform remote client backups and restores, the password you set for the client agent overrides any shared password set for the workstation. If you do not use client agent software for your backup jobs, you must specify share-level passwords on the Backup Manager window. Make sure that the password on the Backup Manager and the share-level password are the same.

Windows Client Agent Configuration

Create Windows Access Control List
You can limit the servers authorized to perform backups on a Windows client agent object by generating an access control list (ACL). This feature is defined through the Backup Manager and the Backup Agent Admin. By creating an access control list and defining its type, you can restrict data backup and restore to a specific group of CA ARCserve Backup servers for the particular client agent. The ACL type can be: No ACL used No list is specified; this is the default. Include list A list of servers allowed to access the client agent machine for backup and restore options. Exclude list A list of servers that are not allowed to access the client agent machine for backup and restore options. All other servers in the network can access the client object. To create a Windows access control list 1. Open the Backup Agent Admin. 2. From the Options menu, select Access Control List.

30 Client Agents Guide

Windows Client Agent Configuration

3. When the Access Control List dialog appears, the default is to not use ACL and the setting All servers will be able to use the agent for backup/restore is selected. To create an ACL, select one of the following choices: ■ ■ Only the listed servers will be able to use the agent for backup/restore All servers will be able to use the agent for backup/restore except the listed ones

4. Click Add to add client agent names to the access control list, including as many names as you need for the ACL. If you want to remove client agents from the list, click Remove for each client agent being removed. 5. Click OK when you finish adding or removing client agent names.

Enable Virus Scanning
CA Anti-Virus software offers extra protection for your critical data, securing it from virus threats even during backup and restore activities. Using this option, you can configure the Windows client agent to automatically detect and repair viruses during a backup, copy, count, or restore operation. To enable virus scanning 1. Open the Backup Manager or the Restore Manager. 2. From the toolbar, click the Options button to display the Global Options dialog. 3. Click the Virus tab. 4. Select Enable Virus Scanning. 5. Click the virus scanning options that you want to apply to the client agent. Available options include: Skip Do not back up or restore an infected file. Rename Rename the infected files with the extension x.AVB (for example, 0.AVB, 1.AVB, 2.AVB). If a file with the same name and the extension AVB exists, the system will name the file with a numeric version of that extension, for example, AV0, AV1, AV2.

Chapter 3: Adding and Configuring the Client Agents 31

Windows Client Agent Configuration

Delete Delete the infected file. Cure CA Anti-Virus cures the files that have been found to be infected. With the Cure option, infected files are automatically repaired during a backup without user intervention. 6. If you want each archive’s component files individually verified, enable Scan Compressed Files. Note: This option may reduce backup or restore performance.

Customizable Local Options
When you explicitly select a parent object (in a parent-child database configuration), you can right-click a client agent object to customize local backup options. For more information on explicit job packaging see the Implementation Guide, and for more information on how to select sources when customizing local options see the Administration Guide.

How the Client Agent for Windows Excludes Database Application Files from Backups
The Client Agent for Windows can exclude database and log files from backups of database applications, such as Microsoft Exchange and Microsoft SQL Server, when performing backups. During the backup job, the Client Agent for Windows communicates with the database agent to obtain a list of files that the backup job should exclude from the file system backup. The Client Agent for Windows then excludes files from the file system backup based on the response received from the database agent. If the database agent is offline, the Client Agent assumes all files should be backed up and the file system backup job proceeds accordingly. Example: When you select a Microsoft Exchange server directory as the backup source and perform file system backup using the Client Agent for Windows, the following exclusion behavior occurs: ■ If the Exchange Information Store is online, the Agent for Microsoft Exchange Server provides a list of the Exchange databases and log files that should be excluded from the backup job. As a result, CA ARCserve Backup skips the excluded files and completes the file system backup.

32 Client Agents Guide

NetWare Client Agent Configuration



If the Exchange Information Store is offline, the Agent for Microsoft Exchange Server provides an empty list of Exchange databases and log files that should be excluded from the backup job. As a result, CA ARCserve Backup does not skip the Exchange server files and includes all files during the file system backup.

NetWare Client Agent Configuration
The following sections discuss the configuration of CA ARCserve Backup NetWare client agent. Note: Your Windows machine must be configured with the Novell client for Windows, so that you can install and run NetWare servers in your network.

NetWare-related Configuration Notes
Be aware of the following issues when configuring the NetWare client agent: ■ Multiple jobs are not supported. The NetWare client agent can service only one job at a time. Trying to submit jobs to the client agent from multiple CA ARCserve Backup servers at the same time may cause the current job to fail. CA ARCserve Backup skips open NetWare files during a backup. When backing up NetWare files using the NetWare client agent, in some cases multiple files are detected as open and are skipped during the backup. Should this happen, select the Retry tab in the Backup Options dialog, and then select the Use Lock Mode if Deny Write Fails option in the File Sharing section, and resubmit the job. NetWare has a 255 character path name limit; for example, DIR1\DIR2\…DIRx. This restriction applies only to NetWare and not to other client agents, such as those for Windows, UNIX or Linux systems. Note: If a NetWare path name exceeds 255 characters, backup and restore operations work properly but path entries are truncated when they are displayed during browsing. Also, the Restore to Original or Alternate Location options still work for restores to the same client agent types.





Configure NetWare Network Communication
To configure the NetWare client agent for communication, edit the ASCONFIG.INI file to specify the IP address assigned to the client agent by the system administrator. Specifying an IP address is useful in a server with multiple IP addresses. Instead of using only the first bound address, the client agent uses the ASCONFIG.INI file to find the IP address to use.

Chapter 3: Adding and Configuring the Client Agents 33

NetWare Client Agent Configuration

To edit the ASCONFIG.INI file 1. From a text editor, open the ASCONFIG.INI file located in the client agent home directory. 2. Add the following line to the NetWare Agent section of the file, specifying the IP address that you want the client agent to use:
IPAddress = nnn.nnn.nnn.nnn

If a NetWare Agent section does not exist, create one by adding the following line to the end of the ASCONFIG.INI file:
[NetWare Agent]

3. Save the file and exit from the editor. 4. Unload and restart the client agent.Unloading is required for changes to the ASCONFIG.INI file to take effect. To unload the client agent, use the NetWare client agent’s Unload & Exit menu option. Alternatively, you can enter the following command at the server console:
unload nwagent

5. When the client agent has been unloaded, restart the client agent (that is, reload the agent) at the server prompt by issuing the following command:
nwagent

A message appears at the server prompt, confirming the use of the IP address specified in the ASCONFIG.INI file:
IP Address nnn.nnn.nnn.nnn from ASCONFIG.INI file will be used.

A similar message is displayed on the client agent runtime message screen:
IP Address nnn.nnn.nnn.nnn is bound for use by NetWare Push Agent.

The client agent is now ready to service backup and restore jobs using the IP address specified in the ASCONFIG.INI file.

Back Up Novell Directory Services
To properly back up Novell Directory Services (NDS), you must enter the full NDS name in the NDS Login name field. For example:
.cn=admin.o=organization_name

When restoring any NetWare sessions, you must supply the full NDS name when prompted for security information.

34 Client Agents Guide

UNIX, Linux, and Mac OS X Client Agent Configuration

UNIX, Linux, and Mac OS X Client Agent Configuration
The UNIX, Linux, and Mac OS X client agent configuration file, uag.cfg, is located on the remote client workstation in the client agent home directory. This file, which is scanned for entries whenever a job is submitted to the workstation, can be used to set multiple options associated with the client agent. Important! Do not change any of the variables in the agent configuration unless instructed to do so by a representative of CA Technical Support.

UNIX, Linux, and Mac OS X Configuration Considerations
The following list describes issues that you should be aware of when configuring the client agent on the UNIX, Linux, and Mac OS X platforms. ■ ■ Session passwords—Session passwords cannot be longer than 22 bytes for UNIX, Linux, and Mac OS X sessions. Single character directory names—You may experience display issues in restore views when restoring single character directory names. The data appears correctly in the database view. Traverse Symbolic Links and Traverse NFS—The options Traverse Symbolic Links and Traverse Network File System (NFS) are not supported for restore operations.



Note: If a configuration discrepancy exists in the CA ARCserve Backup option definitions for these client agents, the options that were set through the Backup Manager always take precedence over the options manually entered in the uag.cfg configuration file.

UNIX, Linux, and Mac OS X Client Agent Control Files
The UNIX, Linux, and Mac OS X client agent control files specify which directories, file systems, or file system types are to be excluded from backup operations on a specific workstation. In particular, the following packages must be installed with the UNIX, Linux, and Mac OS X client agents: ■ ■ The Common Agent The Universal Agent (uagent)

Note: You must install the Common Agent before you install the uagent.

Chapter 3: Adding and Configuring the Client Agents 35

UNIX, Linux, and Mac OS X Client Agent Configuration

The control files installed for both packages include: ■ Directory Control file Use the Directory Control file, uag.cntl, to list all directories or file systems (or both) that you want to exclude from backup operations on a workstation. To specify directories and file systems in this file, enter a slash (/) followed by a one line, complete path name. For example:
/opt/account1

Note: The Directory Control file is stored on the client agent workstation in the uagent home directory. ■ File System Control file The File System Control file, fs.cntl lists the file system types on a particular workstation that are to be excluded from backup operations. To exclude a particular file system type, enter the type on a separate line in the fs.cntl file. Note: The File System file is stored on the client agent workstation in the uagent home directory. ■ Browser Configuration File The Browser Configuration file, cabr.cfg, enables raw devices to be viewed with the browser. You must ensure that you have entered the absolute name of the raw device on a separate line in the cabr.cfg file. ■ Common Agent Configuration File The Common Agent configuration file, agent.cfg, keeps track of each UNIX, Linux, or Mac OS X client agent installed on your system. This script is run automatically after the uagent is installed. Note: Only a system administrator can edit the Directory and File System control files. However, other users may be able to append the files, depending on the file access rights the system administrator has assigned to the file.

Common Agent Configuration File for UNIX, Linux, and Mac OS X
The Common Agent (caagentd binary) is a standard component for all UNIX, Linux, and Mac OS X client agents. It is installed automatically during the first installation of UNIX, Linux, or Mac OS X client agent.

36 Client Agents Guide

UNIX, Linux, and Mac OS X Client Agent Configuration

The Common Agent resides in the /opt/CA/ABcmagt directory. It keeps track of the client agents that are installed on the system in a configuration file named agent.cfg, which also resides in the /opt/CA/ABcmagt directory. Note: CA ARCserve Backup installs related configuration files for the Common Agent, the file system agents, and the Agent for Oracle in different directories on the various UNIX and Linux platforms. For more information, see Installation Directories for the Common Agent and Client Agent For UNIX and Linux (see page 16). During the installation of a new client agent, the agent.cfg file is updated with the new client agent’s information. You will seldom need to modify this configuration file. Manual modification of this file is required only to enable some debugging messages or to change the default TCP/IP port on which the Common Agent runs. A sample agent.cfg file with a client agent installed is as follows:
[0] #[ABagntux] NAME ABagntux VERSION nn.nn.nn HOME /opt/CA/ABuagent ENV CA_ENV_DEBUG_LEVEL=4:$CA_ENV_DEBUG_LEVEL ENV LD_LIBRARY_PATH=/opt/CA/CAlib:/opt/CA/ABcmagt:$LD_LIBRARY_PATH ENV SHLIB_PATH=/opt/CA/CAlib:/opt/CA/ABcmagt:$SHLIB_PATH ENV LIBPATH=/opt/CA/CAlib:/opt/CA/ABcmagt:$LIBPATH BROWSER cabr AGENT uagentd MERGE umrgd VERIFY umrgd [36] DISABLED #[ABcmagt] #NAME ABcmagt #HOME /opt/CA/ABcmagt #TCP_PORT 6051 #UDP_PORT 6051

Common Agent Configuration File Structure
Each section of the agent.cfg file contains groups of fields that directly correspond to an installed client agent on a UNIX, Linux, or Mac OS X device in the backup network. Except for the agent home directory location, all fields in the file are predetermined.

Chapter 3: Adding and Configuring the Client Agents 37

UNIX, Linux, and Mac OS X Client Agent Configuration

The environment variable field (ENV) contents are also determined during client agent installation and configuration. However, if required, you can enter values for this variable into the file manually. You should modify the agent.cfg only in certain circumstances; for example, if you wanted to associate an additional environment field with a particular database. Note: Modifications to the agent.cfg file take effect only after the client agent machine is started (or stopped and restarted). An example of the agent.cfg file is shown in the following table, with a description of each agent field.

File Contents [0]

Field Description Object type, a predefined number of a specific client agent in the network for UNIX and Linux Object type, a predefined number of a specific client agent in the network for Mac OS X Name of the client agent Release and version number of the client agent Default home directory for the client agent Environment variable passed to the client agent Enables the features Snapshot and Direct I/O on Solaris and HP.

38 Client Agents Guide

UNIX, Linux, and Mac OS X Client Agent Configuration

Client Agent Home Directory
The default client agent home directory, ABuagent, is automatically defined during installation and setup. If required, however, you can specify a different home directory. To locate the name of the home directory, look in the agent.cfg file under the ABagntux section of the file. The name of the client agent home directory is defined by the HOME variable.

Common Agent Components
The Common Agent runs at all times as a daemon listening for requests on behalf of all the UNIX, Linux, and Mac OS X client agents that are installed on the system. During each client agent’s installation, the BROWSER, AGENT, MERGE, and VERIFY components are registered with the Common Agent in a separate section. Not all client agents have all of these components. For example, in the following sample configuration file, you can see the BROWSER component cabr, the AGENT component uagentd, and the MERGE and VERIFY component umrgd in the section for the UNIX, Linux, or Mac OS X client agent. Similarly, other client agents use other BROWSER and AGENT components.
[0] #[ABagntux] NAME VERSION HOME ENV ENV ENV ENV BROWSER AGENT MERGE VERIFY

Chapter 3: Adding and Configuring the Client Agents 39

UNIX, Linux, and Mac OS X Client Agent Configuration

Port Address Configuration
The default port for TCP and UDP is 6051. The TCP port is used for communication and data transfer between the backup server (cprocess) and the client agent. The Backup Manager user interface uses the UDP port to browse hosts. If you want to configure either the TCP port or the UDP port, or both, you must modify the configuration files on both the CA ARCserve Backup server and the client agent so that their values match. The names of the configuration files are as follows: ■ ■ CAPortConfig.cfg—for CA ARCserve Backup Windows servers agent.cfg—for client agents

Note: See UNIX, Linux, and Mac OS X Client Agent Control Files for important information about the UNIX, Linux, and Mac OS X configuration files. The following example shows the Windows server configuration file (CAPortConfig.cfg):
#Hostname IP address (optional) TCP port UDP port #myhost xxx.xxx.xxx.xxx 6051 6051

The following example shows the syntax for the client agent configuration file (agent.cfg):
[36] NAME ABcmagt HOME /opt/CA/ABcmagt TCP_PORT 7090 UDP_PORT 7085

Common Agent Port Numbers
By default, the Common Agent uses port number 6051 for both TCP and UDP. To change the default port, you must modify the ABcmagt section of the agent.cfg file with the new port numbers, and then restart the Common Agent by issuing the caagent stop command, followed by the caagent start command. Do not use the caagent update command after modifying port numbers. Note: Under normal conditions, do not use this method to start or stop the Common Agent. Instead, you should run the Start and Stop scripts of the individual UNIX, Linux, and Mac OS X client agents installed on the system.

40 Client Agents Guide

UNIX, Linux, and Mac OS X Client Agent Configuration

The following sample shows the configuration file before and after the script changes are made. Before the change:
[36] #[ABcmagt] #NAME #HOME #TCP_PORT #UDP_PORT

ABcmagt /opt/CA/ABcmagt 6051 6051

After the change:
[36] #[ABcmagt] NAME HOME TCP_PORT UDP_PORT

ABcmagt /opt/CA/ABcmagt 9051 9051

The port changes take effect only after you restart the Common Agent. If you configure the Common Agent to run on a port other than the default port, you should also configure the CA ARCserve Backup server to access this Common Agent. You can do this by making an entry for the client agent in the port.cfg file. This file is in the config subdirectory under the home directory— $BAB_HOME/config/port.cfg—on the backup server. By default, the Common Agent uses another UDP port, 0xA234 (41524), to receive CA ARCserve Backup requests for the Auto Discovery of UNIX, Linux, and Mac OS X client agents. This port is not configurable.

Host Equivalence User Credentials
When the Common Agent checks user credentials, it gives preference to host equivalence settings of the system. A UNIX, Linux, or Mac OS X system can be set up to grant access for specific users on specific hosts without requiring the user to provide credentials. You can grant this access by adding the specific user IDs to the /etc/hosts.equiv or .rhosts file. By default, the Common Agent follows these rules, then checks the user’s password for authorization. To disable host equivalence checking, define the NO_HOSTS_EQUIV=1 environment variable in the agent.cfg file, as shown in the following example:

Chapter 3: Adding and Configuring the Client Agents 41

UNIX, Linux, and Mac OS X Client Agent Configuration

[36] #[ABcmagt] NAME ABcmagt HOME /opt/CA/ABcmagt ENV NO_HOSTS_EQUIV=1

You can place the Common Agent in No Password mode or Single User mode with a set of access control lists if necessary. For more information about ACLs, see UNIX, Linux, and Mac OS X Access Control Lists (see page 50).

How Common Agent Connection Requests Work
To initiate a client agent session, the CA ARCserve Backup server requests a connection for a UNIX, Linux, or Mac OS X client agent to use a specific backup component (such as BROWSER, BACKUP, or RESTORE). When it receives the request, the Common Agent accepts the connection and verifies the user’s credentials for the system. Upon user validation, the Common Agent checks the agent.cfg file for an entry corresponding to that particular client agent and the specified component. Only after it has validated both the client agent and the requested component does the Common Agent activate the client agent and the component. The Common Agent then returns to a state of waiting for additional requests.

Configurable Options
Options are used to optimize and customize the operation of the client agent. However, none of these options are required for the client agent to run. A complete list of options are available for use when starting the UNIX, Linux, or Mac OS X client agents as shown in the following table. Note: These options should be carefully set by administrators having UNIX, Linux, or Mac OS X knowledge. If you do not understand what an option or parameter means, do not set the feature unless instructed to do so by a CA Technical Support representative.

Option -ALLOW <network address> <host address>

Description Use this option with Single User mode, with the -S or -NOPASSWORD option, to define the IP addresses of computers that are authorized to access the client agents without requiring validation.

42 Client Agents Guide

UNIX, Linux, and Mac OS X Client Agent Configuration

-ALLOW N:172.16.0.0(255.255.255.0) H:172.31.255.255

In this example, N denotes a network address and H denotes a host IP address. You can set an optional subnet mask.

Option -b bufsize -c n -CAUSER USER

Description Defines the disk I/O buffer size in bytes. Options are 16384 to 65536 bytes; the default is 65536 bytes. Specifies the sleep time while waiting, in milliseconds (ms). Options are zero (0) to 1000 ms; the default is 50 ms. Defines Single User mode. Used with the -S or NOPASSWORD option to set the Allow or Deny list on a per-user basis.

For example:
-CAUSER A: USER1 N: USER2

In this example, A means –ALLOW and N corresponds to -DENY.

Option -DENY <network address> <host address> For example:

Description Use this option with Single User mode, with the -S or NOPASSWORD option, to define the IP addresses that are not allowed access to the client agents.

-DENY N:172.16.0.0(255.255.255.0) H:172.31.255.255

In this example, N denotes a network address and H denotes a host’s IP address. You can set an optional subnet mask.

Option -l -m maxbuf -NOPASSWORD

Description Causes the client agent to check for advisory locks. The default is mandatory locks only. Sets the number of buffers allocated for I/O. Options are 2 to 1024 buffers; the default is 128. Specify this option if you need to use either the -ALLOW, -DENY, or -CAUSER options. This option is the same as the -S option in Single User mode with no password required.

Chapter 3: Adding and Configuring the Client Agents 43

UNIX, Linux, and Mac OS X Client Agent Configuration

Option -P n

Description Specifies the default time out, followed by a variable number (n), which is user-defined and measured in minutes (0 to 10). The default is 5 minutes.

For example, the option -P 10 assigns a wait time period for the backup or restore pre-script of 10 minutes. Note: An error occurs if you use the -P option without defining a number n.

Option -Prebackup filename -Postbackup filename -Prerestore filename -Postrestore filename -S

Description Executes the default pre-scripts and post-scripts associated with the type of backup or restore job being run. The filename is optional and if is not specified, uag_pre_backup will be treated as the filename.

Enables the Single User mode option. In Single User mode, user credentials are not checked against valid user IDs and passwords. Instead, access is granted based on the -ALLOW, -DENY, or -CAUSER options. For more information see the specific option. Sets socket I/O to asynchronous, nonblocking mode. Specifies the size of the socket buffer. Options are 4096 to 65536. The default is system dependent. Specifies to use socket mode for backup operations. Differentiates between sparse file and regular file operations.This option increases the efficiency of sparse file backups and restores. Note: Quota files are always treated as sparse files in backup and restore operations, regardless of whether you specify –sparse.

-s async| nonblocking -s bufsize -s SocketMode -sparse

-verbose or -v

Places the system in verbose mode to enable the entry of detailed debugging messages at the console.

44 Client Agents Guide

UNIX, Linux, and Mac OS X Client Agent Configuration

Snapshot and Direct I/O Support for UNIX
UNIX client agents support the Snapshot and Direct I/O features. To take advantage of these features, one of the following environments must exist on the machine running the UNIX client agent:

Feature Snapshot

Platform Solaris

Software Requirements UFS file system with the fssnap package installed (Solaris 8 and 9) or the advanced version of VxFS file system. Advanced version of VxFS file system or Online Journaling File System (JFS). UFS file system or VxFS file system. Advanced version of VxFS file system or Online JFS.

Snapshot Direct I/O Direct I/O

HP-UX 11.0 Solaris HP-UX 11.0

Snapshot and Direct I/O Descriptions
With Direct I/O, the client agent takes a snapshot on advanced versions of VxFS, Online JFS (HP-UX), and UFS with fssnap installed on Solaris. The client agent mounts the snapshot to a temporary directory created in the root volume, and then generates the snapshot backup. After the snapshot backup is complete, the client agent dismounts from the temporary directory and deletes the snapshot. To perform a snapshot backup, you must specify a snapshot buffer. A snapshot buffer is the disk space used to store the original data before it is overwritten in the snapped volume. Remember these considerations when using the snapshot buffer: ■ The snapshot buffer needs to be large enough to store all the data that changes in the snapped volume for the duration of the backup. If the snapshot buffer runs out of space, the snapshot becomes invalid and the backup fails. The snapped volume and the snapshot buffer should not be on the same file system. For better performance, the snapped volume and the snapshot buffer should be on separate physical disks. For UFS on the Solaris platform (using fssnap), the snapshot buffer can be a file name, a directory name, or a raw partition.

■ ■ ■

Chapter 3: Adding and Configuring the Client Agents 45

UNIX, Linux, and Mac OS X Client Agent Configuration

For a Direct I/O backup or restore, you need to check the client environment and edit the caagperf.cfg configuration file. You can view Snapshot and Direct I/O on the file systems in the caagperf.cfg file by executing the mount command at the command line after submitting the backup or restore job. For Snapshot, the output that appears after executing the mount command is a new, read-only file system with the mount point starting with the prefix SNAP_HOME_ . A Direct I/O user can observe the changes in the mount options on that particular file system. You can also see the detailed messages in the caagperf.log file if you enabled the logging flag in the caagperf.cfg file. The following sections describe how to configure a UNIX client agent to use these features.

Configure Snapshot and Direct I/O
To configure the Snapshot and Direct I/O features, follow these steps: 1. Enable the environment variable CAAGPERF_ENABLE by adding the following line in the agent.cfg file:
ENV CAAGPERF_ENABLE=1

Note: The agent.cfg file is in the /opt/CA/ABcmagt directory. After you enable this environment variable, the client agent section of the agent.cfg file looks like this:
[0] NAME VERSION HOME ENV ENV ABagentux nn.nn.nn /opt/CA/uagent LD_LIBRARY_PATH=/usr/local/Calib:/opt/CA/ABcmagt CAAGPERF_ENABLE=1

2. Prepare the configuration file named caagperf.cfg in the /opt/CA/ABcmagt directory. You need to specify the types of operations to be completed on the specified file systems in the caagperf.cfg file. See the next section for detailed descriptions.

46 Client Agents Guide

UNIX, Linux, and Mac OS X Client Agent Configuration

Configuration Table Parameters and Values
The format of the configuration file is similar to a Windows .inf file. It has sections and key value pairs. The section names are the names inside the square brackets, and the key value pairs are in KEY=VALUE format with one pair on each line. All the entries in the configuration file are case-sensitive. The key value pairs are under the volumes to which they belong, and the section names are the names of those volumes. Two examples of the syntax of the section name in the caagperf.cfg file are [/] or [/export/home]. If a volume has multiple entries, the behavior of the client agent is undefined. The key value pairs are used to set parameters for the volume under which they belong. By default, all options are disabled. If no special processing is needed for a volume, that volume should not be in the caagperf.cfg file. The keys and their values are described in the following table:

Key DOSNAP

Value Enables the Snapshot feature on a volume. The value should be BACKUP, meaning that a snapshot should be taken during the backup operation. Specifies the buffer used for storing original data before it is overwritten in the snapped volume. The value should be a file name or partition. The file can be a file or a directory from a different volume. The value of this field depends on the file system type. For the advanced version of VxFS or Online JFS, the value is the name of an empty partition. For UFS, the value is a file name, a directory name, or a partition name.

SNAPSHOTBUFFER

DOUBIO

Enables the Direct I/O feature on a volume. Values are BACKUP, RESTORE, and BACKUP_RESTORE. The value of this field depends on your backup or restore requirements.

You may find the following configuration file samples useful.

Chapter 3: Adding and Configuring the Client Agents 47

UNIX, Linux, and Mac OS X Client Agent Configuration

Configuration Files for UNIX Systems
The following are examples of different variations of UNIX systems configuration files. Example: Solaris 8 or Solaris 9 operating system with a UFS file system with fssnap installed The first line of the file is a debugging flag. The three sections that follow the debug entry correspond to the /opt, /export/home, and / volumes on the disk. The sections for /opt and /export/home have Snapshot enabled during backup, and the / section has Direct I/O enabled for backup and restore.
##DEBUG [/opt] DOSNAP=BACKUP SNAPSHOTBUFFER=/garbage/snapbufferfile_1 [/export/home] DOSNAP=BACKUP SNAPSHOTBUFFER=/garbage/snapbufferfile_2 [/] DOUBIO=BACKUP_RESTORE

Example: Solaris 8 operating system with the advanced version of the VxFS file system installed The file contains three sections. The first line of the file is a debugging flag. The three sections in the file are /opt, /export/home, and / volume. Sections for /opt and /export/home have Snapshot enabled during backup, and the / volume has Direct I/O enabled for backup and restore.
T##DEBUG [/opt] DOSNAP=BACKUP SNAPSHOTBUFFER=/dev/dsk/c0t0d0s4 [/export/home] DOSNAP=BACKUP SNAPSHOTBUFFER=/dev/dsk/c0t0d0s4 [/] DOUBIO=BACKUP_RESTORE

Trace Levels for the AS/400 Enterprise Option
Occasionally, based on instructions from CA Technical Support, you may need to change the level of activity that is logged for the AS/400 Enterprise Option. Because tracing levels can affect backup performance, do not change the values unless you receive specific instructions from CA Technical Support. The following table shows all of the AS/400 Enterprise Option trace levels:

Level ASO$TRACE

Description This controls the trace depth of the client agent. Valid values are -1 and 0 to 0xFFFFFFFF. Setting the ASO$TRACE value to –1 logs the most detail. This is a toggle. If defined, Asynchronous System Traps (ASTs) are traced. This is a formatting parameter. The recommended value is between 0 and 5. The default is 3. This controls the number of bytes in each packet that is logged. The range is unlimited and starts at 0. The default is 300.

UNIX, Linux, and Mac OS X Client Agent Configuration

UNIX, Linux, and Mac OS X Access Control Lists
For UNIX, Linux, and Mac OS X client agents, ACLs are supported in Single User mode only. This is also known as No Password mode. A UNIX, Linux, and Mac OS X client agent—or database backup agent—can be put into Single User mode by specifying a NOPASSWORD entry in its corresponding section in the Common Agent configuration file, agent.cfg, located in /opt/CA/ABcmagt. A UNIX, Linux, and Mac OS X client agent can also be put into Single User mode by specifying the -S or -NOPASSWORD option in the uag.cfg. You can use two types of ACLs with the UNIX, Linux, or Mac OS X client agent: Example: Allow or Deny Users An access control list can deny or allow specific users to perform backups or restores. For example, a part of the agent.cfg file is shown in the following sample. You need to make similar changes for other client agent sections if you want to apply ACLs to those client agents too.
[0] NAME ABagentux VERSION nn.n.n HOME /opt/CA/ABuagent NOPASSWORD CAUSER A:CAUSER1 N:CAUSER2

NOPASSWORD enables Single User mode, and CAUSER specifies the users for whom permission is being granted or denied. (A stands for ALLOW and N stands for DENY.) A:CAUSER1 enables CAUSER1 to perform jobs, and N:CAUSER2 denies access to CAUSER2. Note: For UNIX and Linux client agents, the object type is [0]. For the Mac OS X client agent, the object type is [4].

50 Client Agents Guide

UNIX, Linux, and Mac OS X Client Agent Configuration

Example: Access the System with IP Addresses An access control list can determine whether specific IP addresses can access the system. For example, a part of the agent.cfg file is shown in the following sample. You must make similar changes for other client agent sections of the file if you want to apply ACLs to those client agents too.
[0] NAME ABagentux VERSION nn.n.n HOME /opt/CA/ABuagent NOPASSWORD ALLOW N:172.16.0.0(255.255.255.0) H:172.31.255.255 DENY N:192.168.0.0(255.255.255.0) H:192.168.255.255

NOPASSWORD enables the Single User mode, and ALLOW and DENY specify whether a particular network or IP address is allowed to access the system. N denotes a network address and H denotes a host’s IP address. Note: An optional subnet mask can follow a network address; subnet masks are shown in parentheses. For UNIX, Linux, and Mac OS X client agents, the specific type of ACL can be specified in uag.cfg, or you can specify them using the -S, -NOPASSWORD, -CAUSER, -ALLOW, and -DENY options. For more information about these options, see the section Configurable Options. You can apply both types of ACLs concurrently. In each case, DENY takes precedence over ALLOW. In the Single User mode, all operations on the client agent are performed with superuser privileges. The caagentd.log contains information about the users, IP addresses, and network addresses denied during Single User mode.

Backup and Restore Access Control List Support for UNIX and Linux
CA ARCserve Backup Client Agent for UNIX, CA ARCserve Backup Client Agent for Linux, and CA ARCserve Backup Client Agent for Mainframe Linux back up and restore the access control list (ACL) for files and directories on a Linux system that have been backed up using the Linux client agent. The extended attributes for Linux are also backed up. ACL gives administrators finer control over files and directory access. The Linux client agent can read and set the ACL for each file and directory.

Chapter 3: Adding and Configuring the Client Agents 51

UNIX, Linux, and Mac OS X Client Agent Configuration

Verify ACL Libraries
To check that you have the required ACL libraries installed, run the following command:
>rpm -qa |grep libacl

If the libacl-devel-* or libacl-* packages are not listed, you must install them.

Install ACL Library Packages
To install ACL library packages 1. Copy the ACL library packages from the CD image, or download them from the internet to your Linux system:
-libacl package (such as libacl-2.2.3-1.rpm) -libacl-devel package (such as libacl-devel-2.3.3-1.rpm)

2. To install the packages, run the following commands:
rpm -ivh <libacl-package-name> rpm -ivh <libacl-devel-package-name>

as in this example:
>rpm –ivh libacl-2.3.3-1.rpm >rpm –ivh libacl-devel-2.3.3-1.rpm

This step installs the libacl.so library into your Linux system. If the Linux client agent is running on a 32-bit Linux system, ACL support is now enabled. If the Linux client agent is running on a 64-bit Linux system, you must ensure that the libacl.so library is a 32-bit version. You can check the version and create a link to a 32-bit library if necessary.

Verify the Linux ACL Library Version
To check the version, go to the directory where libacl.so is installed. Verify the Linux ACL library version 1. Run ls –l . /libacl.so to display the libacl.so linking target library file. 2. Run file libacl.so<-linking-target-library> using the library file name. The result will show whether libacl.so points to a 32-bit or 64-bit version.

52 Client Agents Guide

AS/400 Enterprise Option Configuration

Create Link to 32-bit Linux ACL Library
If libacl.so points to a 64-bit library, you must create a link from the 32-bit library to libacl.so. The following example shows how to create the link on a 64-bit Mainframe Linux platform:
> cd /lib > ln -sf libacl.so.1 libacl.so

Use the appropriate link command for your 64-bit Linux system.

AS/400 Enterprise Option Configuration
The AS/400 Enterprise Option start and stop preferences are configured using STRASO and ENDASO.

Configure Start Preferences
Library Level Backup preferences can be configured to enhance the AS/400 Enterprise Option. To configure start preferences 1. From the command line, type:
straso

2. Press F4. The available options display.

Chapter 3: Adding and Configuring the Client Agents 53

AS/400 Enterprise Option Configuration

3. Type your preferences and press Enter. Note: You can configure the preferences for Library Level Backup and Use QaneSava. These preferences enhance performance. For more information, see the section Performance Configuration.

Performance Configuration
By default, both Use QaneSava and Library Level Backup are set to *ON. These settings increase the performance of the agent for library level backups. Use the Use QaneSava flag to toggle between *ON and *OFF. With the Use QaneSava flag set to *ON back ups are executed without creating a temporary SAVF file. By setting the flag to *OFF, backups are executed and will create a temporary SAVF file. Use the Library level backup flag to control the backup of libraries. When the Library level backup flag is set to *ON, the SAVLIB command is applied to library objects. The SAVLIB command improves performance because it saves both library information and all files inside a library in one backup. The Library Level Backup feature is especially useful when performing multiple library backups.

54 Client Agents Guide

OpenVMS Enterprise Option Configuration

By setting the flag to *OFF, the SAVOBJ command is used to back up each file inside a library separately. Use this approach if you are not intending to do Library Level Backups. Note: The Library Level Backup feature does not support incremental and differential backups.

Configure Stop Preferences
If necessary, you can set stop preferences for the AS/400 Enterprise Option. To configure stop preferences 1. From the command line, type:
endaso

2. Press F4. The options display on the configuration screen. 3. Type your preferences and press Enter.

OpenVMS Enterprise Option Configuration
Other than the port address, the OpenVMS Enterprise Option does not require additional configuration after installation.

Chapter 3: Adding and Configuring the Client Agents 55

OpenVMS Enterprise Option Configuration

Configure Port Address
The default TCP and UDP port addresses are both 6050. The TCP port is used for communication and data transfer between the cprocess and the client agent. CA ARCserve Backup uses the UDP port to browse the hosts. If you want to configure the TCP port or the UDP port, include the following command in the bab$startup.com file:
DEFINE /SYSTEM ASO$PORT_NUMBER nnnn

In this example, nnnn is the port number of the Backup Manager. Important! OpenVMS requires that both the UDP and TCP ports be assigned the same port number.

TCP/IP Stack Optimization
The configuration of the TCP/IP stack can affect client agent performance. Typically, the TCP Send and Receive quotas are set to 4096. Set these values to the largest value allowed by the specific stack installed on the OpenVMS system.

Trace Levels for the OpenVMS Enterprise Option
Occasionally, based on instructions from Computer Associates Technical Support, you may need to change the level of activity that is logged for the OpenVMS Enterprise Option. Because tracing levels can affect backup performance, do not change the values unless you receive specific instructions from CA Technical Support.

Level ASO$TRACE

Description This controls the trace depth of the client agent. Valid values are -1 and 0 to 0xFFFFFFFF. Setting the ASO$TRACE value to –1 logs the most detail. This is a toggle. If defined, Asynchronous System Traps (ASTs) are traced. This is a formatting parameter. The recommended value is between 0 and 5. The default is 3.

Chapter 4: Using the Client Agents
This chapter includes details such as how you can start and stop client agents, and how you can schedule or initiate backup and restore jobs of client agents in a standard backup environment. This section contains the following topics: Runtime Statistics (see page 57) Activity Logs (see page 58) Back Up Windows Network Server Data (see page 62) Client Agent Start and Stop Procedures (see page 62)

Runtime Statistics
The client agent runtime components for both Windows and NetWare provide real-time statistics and display the progress of backup and restore jobs as they are being processed. Note: Runtime statistics apply only to Windows and NetWare.

View Runtime Statistics for the Client Agent for Windows
CA ARCserve Backup lets you view runtime statistics for computers running the Client Agent for Windows. To view runtime statistics for the Client Agent for Windows 1. From the Windows Start Menu, select Programs, CA, ARCserve Backup, and click Backup Agent Admin. The Backup Agent Admin opens. 2. Select Connections. CA ARCserve Backup displays the last 32 jobs processed. If the job is still active, you can click the job to display its current runtime statistics. If the job has completed, completed statistics for that job are displayed. Note: The statistics are stored in memory. Therefore, if you close the Backup Agent Admin and the Universal Agent service, the connection statistics will be lost. However, you will still be able to view the results of the job in the Activity Log.

Chapter 4: Using the Client Agents 57

Activity Logs

View Runtime Statistics for the NetWare Client Agents
With the NetWare client agent, if the Runtime window is not available, you must switch windows to display it. If you are running Remote Console (RCONSOLE.EXE) to view the server console, press the ALT and F3 keys simultaneously and continue pressing the keys until the Runtime window opens. If you are at the server console, press the ALT and ESC keys simultaneously to switch windows. Note: You can press the Ctrl and ESC keys simultaneously to display a list of current windows, and then you can choose the Runtime window.

Activity Logs
The server-based CA ARCserve Backup system generates an activity log, which displays information about all the jobs that the client agent processes. The following sections explain how to display the activity log for each client agent from the server side and from the client agent side.

View Activity Logs on a Windows Server
To view the activity log on a Windows CA ARCserve Backup server 1. From the Quick Start menu on the CA ARCserve Backup Manager Console, select Job Status. The Job Status Manager opens. Click the Activity Log tab to view a list of logs, as shown in the following example:

58 Client Agents Guide

Activity Logs

2. From the Job Status menu, select Activity Log and click Print Preview. The print preview output of a client agent activity log file appears as illustrated by the following screen:

View Activity Log on a NetWare Client Agent Machine
The NetWare client agent writes to the nwagent.log, which is created in the client agent home directory. You can view this log using Windows Explorer by opening the file in the client agent home directory. Alternatively, you can view log file contents by selecting View nwagent.log at the console.

View Activity Log on a UNIX, Linux, or Mac OS X Client Agent Machine
As soon as the UNIX, Linux, or Mac OS X client agent begins running, an activity log file called uag.log is created and stored in the logs directory. The logs directory resides under the client agent home directory. The uag.log file records all activities and errors that occur during machine backup and restore jobs. Each job is identified numerically in sequence, as well as by date and time, in the log display. On the client agent machine, you can view the contents of these logs using the print filename command. Note: All log messages relating to the Common Agent are located in the /opt/CA/ABcmagt/logs/caagentd.log file.

Chapter 4: Using the Client Agents 59

Activity Logs

Activity Logs on Computers Running the AS/400 Enterprise Option
The Enterprise Option for AS/400 creates a log file in the CA ARCserve Backup library. The two file members are: ■ ■ AGENT.MBR, which records the activities and errors relating to agent operations ASBR.MBR, which records information on CA ARCserve Backup browsing activities

Activity Logs on Computers Running the OpenVMS Enterprise Option
As soon as the agent begins running on the server, CA ARCserve Backup generates an activity log file named aso$agent_<nodename>.log, and stores it in the logs directory. A new log file—identified by sequential job number, date, and time— is created for each job and every subsequent startup of the agent. The content of each log file is determined by the level of tracing enabled on the agent.

Activity Logs

Delete Client Agent Log Files
For UNIX, Linux, and Mac OS X client agents, delete log files from the client machine the same way you would delete any file on that machine. For example, run:
$>rm uag.log

For Windows client agent, use the Backup Agent Admin to delete log files. In the Options menu, select Delete Client Agent Log Files. Select the log files you want to delete and click Delete, as shown in the following illustration:

Chapter 4: Using the Client Agents 61

Back Up Windows Network Server Data

Back Up Windows Network Server Data
If you installed a client agent on a Windows server, you can back up the server data through the client agent. To back up Windows network server data 1. Open the Backup Manager. 2. Click the Source tab. 3. Expand the Network object, and then expand the Windows Systems network object until you locate the client machine. 4. Right-click the client machine. Choose Use Agent from the pop-up menu. 5. Check the Use Agent check box. 6. Select a protocol. Either select TCP/IP and enter the address for the client computer or select Use Computer Name Resolution, to specify that the client agent should determine an IP network address using the Dynamic Host Configuration Protocol. 7. Click OK. The client agent is now selected. 8. If you are prompted for security, enter the appropriate security for your environment.

Client Agent Start and Stop Procedures
The following sections describe the procedures for starting and stopping the various client agents. Note: If the client agent is stopped at any time during a backup or restore job, the job will fail and must be restarted.

Windows Start and Stop Requirement
The Windows client agent uses a common component called the Universal Agent. This component is installed or updated during installation. The Universal Agent is registered as a service that starts automatically and runs under the local system account by default. When the service starts, the Windows client agent is loaded. The Windows client agent is available even when no users are logged into the system. Use the Backup Agent Admin to start or stop the Windows client agent. The Backup Agent Admin monitors the client agent activity and protects against accidental job failures if the Universal Agent service stops.

62 Client Agents Guide

Client Agent Start and Stop Procedures

Start or Stop the Windows Client Agent
To start or stop a Windows client agent 1. Open the Backup Agent Admin. 2. From the Options menu, select Services. 3. (Optional) If you do not want the client agent to start automatically each time you start the computer, clear the option, Start the backup agent service as the system starts. 4. Click the arrow to start the service or the red dot to stop the service. Note: Stopping the service affects other components that use the Universal Agent. 5. Close the Backup Agent Service Manager.

NetWare Start and Stop Requirement
The installation process for the NetWare client agent creates a Network Client Facility file called NWAGENT.NCF. Before starting the client agent, ensure that this file was created and stored properly in the SYSTEM directory on the NetWare server’s SYS volume.

Start the NetWare Client Agent
To start the NetWare client agent, issue the following command at the remote server console prompt:
nwagent

The NetWare client agent includes a module called CSLOADER.NLM, which performs monitoring functions. When you start the NetWare client agent, CSLOADER.NLM also starts. CSLOADER.NLM displays, and records in log files, the results of this process as a series of informational messages. These messages can be helpful in tracking the source of a problem. CSLOADER.NLM also works with the Pre-Flight Check (PFC.NLM), which evaluates the environment in which the client agent will be running. If the environment fails to meet its requirements, this checking mechanism signals CSLOADER.NLM to stop the loading sequence.

Stop the NetWare Client Agent
To stop the NetWare client agent, issue the following command at the NetWare server console prompt:
unload nwagent

Chapter 4: Using the Client Agents 63

Client Agent Start and Stop Procedures

UNIX, Linux, and Mac OS X Client Agents Start and Stop Requirement
Before starting the client agent, ensure that it has been configured. If the client agent has not been configured, run the following script:
#abuagent/uagentsetup

In this example, abuagent represents the full path name of the agent home directory. The default path is /opt/CA/ABuagent.

Start the UNIX, Linux, or Mac OS X Client Agent
After installing a UNIX, Linux, or Mac OS X client agent, the agent is started automatically. To check the status of the agent, type the following command at the command line:
# uagent status

To start the agent, type the following command at the command line:
# uagent start

If the agent is not enabled, run the configuration script, uagentsetup.

Stop the UNIX, Linux, or Mac OS X Client Agent
To stop the UNIX, Linux, or Mac OS X client agent, log in as root and type the following command at the command line:
# uagent stop

Common Agent Start and Stop Status
Whenever a client agent is started or stopped, the UNIX, Linux, or Mac OS X system scripts modify the agent.cfg file by marking the client agent entry in the file as enabled or disabled. The scripts also notify the Common Agent of the change. The Common Agent then determines whether to continue running, depending on the number of entries in the configuration file that are still enabled. For example, issuing uagent stop for a UNIX client marks the ABagntux section disabled. If ABagntux is the only section of the file (that is, there is only one CA ARCserve Backup client agent installed), the Common Agent stops. You would then need to issue uagent start to enable the ABagntux section of the agent.cfg file.

64 Client Agents Guide

Client Agent Start and Stop Procedures

When you enter the uagent start command, the Common Agent status changes from disabled to enabled. In summary, when a particular client agent is started or stopped, the scripts modify the agent.cfg file accordingly, and notify the Common Agent. At that point, the Common Agent decides whether to continue running, depending on the number of sections in the configuration file that are still enabled.

Check the Status of the UNIX, Linux, and Mac OS X Client Agents
To check the status of a UNIX, Linux, or Mac OS X client agent, log in as root and issue the following command at the command line:
# uagent status

If this command fails, the client agent may need to be configured. To configure the client agent, run the following script:
#abuagent/uagentsetup

In this example, abuagent represents the full path name of the agent home directory. The default path is /opt/CA/ABuagent.

Enterprise Option for AS/400 Start and Stop Requirement
You must have *JOBCTL (job control) authority to start or stop the client agent.

Start the Client Agent for Enterprise Option for AS/400
To start the agent, log on to AS/400 and issue the following command at the command line:
straso

Stop the Client Agent for Enterprise Option for AS/400
To stop the agent, log on to AS/400 and issue the following command at the command line:
endaso

Enterprise Option for OpenVMS Start and Stop Requirement
Ensure that you have the appropriate network credentials to operate the OpenVMS machine on which the client agent resides.

Chapter 4: Using the Client Agents 65

Client Agent Start and Stop Procedures
