System Restoration

B.

The term used to restore a system to its operational state is known as MTTR or Mean Time To Restore.

MTTR is a measure of the average time required to repair a system or component and restore it to normal operations after a failure or disruption. The lower the MTTR, the faster a system can be restored to full functionality, and the less impact the disruption will have on operations.

MTBF (Mean Time Between Failures) is a related concept, but it refers to the average time between failures or disruptions in a system or component. A longer MTBF indicates that a system is more reliable and has fewer failures or disruptions over time.

RTO (Recovery Time Objective) and RPO (Recovery Point Objective) are also related concepts, but they refer specifically to disaster recovery planning. RTO is the targeted duration of time within which a business process must be restored after a disaster or disruption, while RPO is the targeted point in time to which data must be recovered after a disaster or disruption.

In summary, MTTR refers to the time it takes to restore a system to its operational state, while MTBF refers to the time between failures or disruptions. RTO and RPO are related concepts, but they refer specifically to disaster recovery planning.
