Re: [ovirt-users] Mount iscsi snapshot as another data domain

 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

 Subject: [ovirt-users] Mount iscsi snapshot as another data domain
 
 Hello,
 if I have an iscsi san that can do snapshots can I take an old snapshot and
 reimport in ovirt as another data domain?

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?


 So I can recover old versions of virtual machines.
 
 Thanks,
 Mario
