Hi Hemanth,

What is the purpose you want to backup your VM?
Today, there are several ways you can backup a VM:

1. Create a snapshot - 
      This way you backup your VM state and the data on the disks at a specific point in time while the VM can be running or not, the backup of the VM's disks will be reside on the same Storage Domain which the disks are reside on.
2. Create a Template - 
      It will preserve the VM configuration (memory and CPU) and also the disks, though it is a copy operation which might take time and the VM should be shut down in the process
3. Export the VM to an export domain - 
       This way your VM will be backed up in a different "special" Storage Domain, which can be moved between different setups and Data Centers. Your VM should be shutdown for this and this is also a copy operation which might be time consuming.
4. Import Storage Domain - 
       A new feature introduced in oVirt 3.5 is import Storage Domain, which intends to support disaster recovery to your oVirt setup. 
       One of its major features is that it backs up automatically, every 60 minutes, your VM's data in the Disks' Storage Domains.
       The feature is only supported in 3.5 Data Center or up.
       see at http://www.ovirt.org/Features/ImportStorageDomain for more details.
       To see how to use it you can check out the following links:
