I've migrated our storage to zfs (all you need is cache='writeback' in
/etc/libvirt/qemu/machine.xml) and added a cron job to snapshot it and
copy the snapshot to another zfs nightly. I keep a week's worth of
snapshots, I don't need any more backups than that

-- but if I did, I too would back up the actual data I need from within
the VM.
