In the area of data protection, the key factors are the recovery point objective (RPO) and the recovery time objective (RTO), which determine the various possible solutions and choices for post-failure recovery. RPO corresponds to the maximum quantity of data that can be acceptably lost when a breakdown occurs. Daily backup is the technique generally used for a 24-hour RPO. For an RPO of a few hours, snapshots and asynchronous replication are used. An RPO of 0 involves setting up a synchronous replication mode and corresponds to a request for “no data loss.”
