I can see the obvious distinction between cinder-snapshot and<br>
cinder-backup being that snapshots would live on the same storage back<br>
end as the active volume (using that ever snapshotting that provides)<br>
where the backup would be to different storage.<br>
<br>
We're using Ceph for volume and object storage so it seems like<br>
running cinder-backup in that case (with active, snap, and backup<br>
would be all in essentially the same backend) would not make a whole<br>
lot of sense.<br>
<br>
Is my thinking right on this or are there advantages of 'backup' over<br>
'snapshot' that I'm not considering?<br>
