[Openstack] cinder-snapshot -vs- cinder-backup?

Re: [Openstack] cinder-snapshot -vs- cinder-backup?

One of the extra benefit could be that you’re doing backup on another Ceph cluster (potentially on another location). However this will never prevent you from corruption since if corruption already occurred then it will be replicated. Like Erik mentioned a catastrophic situation were you lose al
