[Users] Hot Snapshotting of virtual disks

[Shu Ming]

Basically, backup is different from snapshotting. Backup should have 
another storage different from the current share storage to store the 
disk content. oVirt 3.1 does have support for live snapshot of the VM 
disks and Qemu 1.1 is required at least to support this operation. In 
oVirt 3.1, you can also create an backup domain to store the VM disks, 
but I think it is not the real backup to another physical storage. So 
you may have to copy the snapshot made to other physical storage manually .

Most of the others have serious drawbacks, so I wanted to know if anyone had a silver bullet before I put more time into it.
