Re: [Xen-users] Xen Project backup

[Keith Roberts <keith.roberts@xxxxxxxxxxxx>]

Personally I take regular snapshots of the PV VM’s to a second ext4 RAID array 
on the server. They are then copied away from the server to separate networked 
drives.

As for the physical VM host - that OS gets backed up using clonezilla when all 
VM’s and the server are offline.
