Mean time to repair (MTTR) describes the time needed to resolve a hardware issue with a server. MTTR is a key metric in risk management and maintenance that measures the average time required to repair a failed component or system and restore it to operational status. * Recovery point objective (RPO): Defines the maximum acceptable amount of data loss measured in time. It is the point in time to which data must be restored after a disaster. * Mean time between failures (MTBF): Measures the average time between failures of a system or component, indicating reliability. * Recovery time objective (RTO): Defines the maximum acceptable length of time to restore a system after a disaster or disruption. * Mean time to repair (MTTR): Measures the average time required to repair a failed component or system.
