Abstract: A cluster storage system takes snapshots that are consistent across all storage nodes. The storage system can nearly instantaneously promote a set of consistent snapshots to their respective base volumes to restore the base volumes to be the same as the snapshots. Given these two capabilities, users can restore the system to a recovery point of the user's choice, by turning off storage service I/O, promoting the snapshots constituting the recovery point, rebooting their servers, and resuming storage service I/O.
