Which of the following defines a business goal for system restoration and acceptable data loss?

MTTR (Mean Time To Repair) measures the average time required to restore a failed component or system, not acceptable data loss.

MTBF (Mean Time Between Failures) measures the average operational time between system failures, which is a reliability metric, not a recovery goal.

RPO specifies the maximum acceptable age of data that must be recovered after an incident, effectively defining the business tolerance for data loss and the target restoration point. It is a core disaster recovery planning metric that drives decisions about backup frequency and replication strategies.

A warm site is a type of disaster recovery facility with partially pre-configured infrastructure, not a metric that defines restoration goals or data loss tolerance.
