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:

Hello Maor,
I am worried, What happens if the storage domain fails. i.e what if the
harddisk where the storage domain is residing fails?.
I just wanted to have a external backup.

Hello Maor,
I am worried, What happens if the storage domain fails. i.e what if the
harddisk where the storage domain is residing fails?.
to avoid this you can either use option number 3 (export domain)
or use a template and copy the disks to several different Storage Domains
I just wanted to have a external backup.
If you can use an external backup to backup only your Storage Domains on the storage
server, then you can use the Import Storage Domain feature more safely,
since if, at any time, your Storage Domain will be ruined, you can create a new setup and
import it the backed-up Storage Domain.

Hemanth
