If you use direct LUN option for a VM image, you can take a snapshot of that LUN on the SAN and attach it as another direct LUN and eventually boot from that. Do you really need to take an online snapshot of the whole storage domain with all the VM in a single shot?

Actually I am searching a backup and easy disaster recovery strategy.

I prefer to not put each vm on its lun because it seems very difficult to manage. I would like to let ovirt manage my storage.

Snapshotting all storage can be an easy way to do backups if I can quickly import again the storage domain and start an old version of a vm.

The other option I can evaluate is to use ovirt api for backups but, as far as I know, there are no opensource backup solutions that use that api.

Am I right?

Thanks again,

Mario
