A financial services company is updating its business continuity plan. For its critical online transaction processing system, the management team has determined that the system can be unavailable for a maximum of one hour before causing unacceptable business disruption and financial loss. Which business continuity metric does this one-hour time limit represent?
Recovery Time Objective (RTO) is the target time within which a business process must be restored after a disaster or disruption to avoid unacceptable consequences. In this scenario, the one-hour maximum acceptable downtime is the RTO.
Recovery Point Objective (RPO) is a different metric that defines the maximum acceptable amount of data loss, measured in time (e.g., "we can afford to lose up to 15 minutes of data").
Mean Time to Repair (MTTR) is a reliability metric representing the average time required to repair a failed component or device. Unlike RTO, which is a future-facing target for a specific process, MTTR is a historical average of repair times.
Mean Time to Detect (MTTD) is the average time it takes to discover that an incident has occurred.
Recovery Time Actual (RTA) is the real time it takes to complete a recovery, which is measured during a test or actual incident and compared against the RTO.
