Hi Alfredo,

What kind of backup/restore plan do you have planned?

Because snapshots are not meant to be used in a Disaster Recovery
backup/restore plan, so the only thing available are the manage/unmanage

These commands are meant to add an existing volume/snapshots into Cinder
together, not to unmanage/manage them independently.

For example, you wouldn't be able to manage a snapshot if the volume is
not already managed.  Also unmanaging the snapshot would block the
deletion of the RBD volume itself.
