Which term stands for the maximum tolerable period of data loss in DR planning?

• A. RTO
• B. MTTR
• C. RPO
• D. RCO

Answer: (C)

In disaster recovery planning, the maximum amount of data you can afford to lose is Recovery Point Objective. It defines the age of the data that you’re willing to restore to after a disruption, which in turn drives how often you need to back up or continuously replicate data. If your RPO is four hours, your backups or replication must ensure that at most four hours of data could be lost, so you’d schedule frequent data protection accordingly. This is different from the downtime you can withstand (RTO), which concerns how long services can be unavailable, and from the time to repair something (MTTR). The term shown isn’t a standard DR metric, whereas Recovery Point Objective directly addresses data loss tolerance.
