3.1 Data vault and Backup File System
Data vault is a network model in which the data is backed
up and stored using an internet connection on remote
servers. The service providers (hosting companies)
provide large data centers and users who want to access
their data or to store it buy or lease storage space from the
servers. Virtualization is used by the data center managers
often to reserve resources based on the requirements of
the customer and storage spaces are allotted to back up
their files or data objects. Physically, These resource can
protract along pooled servers and locations. The
confidentiality provided to the user data purely depends
on the service provider. PVFS2 file system had been
selected for our data vault; as it is open source, we have
the flexibility to use and modify according to our
compulsion. Let us know how these file systems actually
manage the backup and storage of files within the input /
output.

4. RESULTS
The test program used for concurrent write performance
is pvfs-test, which is included in the PVFS release package.
In all tests, each compute node writes and reads a single
contiguous region of size 2N MB, where N is the number of
I/O nodes in use. The results obtained prove that the
performance of PVFS2 is far better than the existing file
system. The same is shown in the table given below and
the results are depicted in the graph.
