Hi Shu,
Sorry I didn't go into more detail, yes I intend to copy the snapshot to a
different medium (potentially to a DR site, at the very least to an independent
NAS). The snapshot is just so I can grab a consistent copy of the disk (even
though I understand it risks filesystem corruption due to incomplete writes) If
oVirt now supports hot snapshots it in 3.1 we will look into this.
yes, live snapshots are part of 3.1

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 .

Hi,
Can anyone give advice on what they are using for backup on their ovirt
deployments. We have been using tar balls & rsync on our linux servers, but are
looking for something more manageable and the number of servers grows rapidly.
I ask because I have been looking at a few options. The first idea that came to
mind was a hot snapshot of the virtual disk, however from what I can see ovirt
won't allow that. 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.
Jason
