Backed up snapshots are read-only when accessed from the original site. Restoring a volume from a backup is a matter of instantiating (cloning) the snapshot in the original site. This is controlled through API or CLI.
Backed up snapshots can also be transferred to a remote site when needed. This is controlled through API or CLI as well.
