Hi, When using cinder-backup, it first makes a snapshot, then sends the backup wherever it's configured. The issue is, to perform a backup, one needs to make a snapshot of a volume, meaning that one needs the size of the volume as empty space to be able to make the snapshot.
So, let's say I have a cinder volume of 1 TB, this mean I need 1 TB as empty space on the volume node so I can do a backup of that volume. My question is: is there a way to tell cinder to reserve an amount of space for this kind of operation? The only thing I saw was reserved_percentage, but this looks like for thin provisioning only. If this doesn't exist, would such new option be accepted by the Cinder community, as a per volume node option? Or should we do it as a global setting?
