What is the difference between MTBF & MTTR

Question

Accepted Answer

MTBF is the average time between failures, while MTTR is the average time to repair a failed system.

MTBF stands for Mean Time Between Failures and represents the average time a system operates before a failure occurs.
MTTR stands for Mean Time To Repair and represents the average time it takes to repair a failed system and restore it to normal operation.
MTBF is a measure of system reliability, while MTTR is a measure of maintainability.
MTBF + MTTR = Mean Time To Failure (MTTF), which is the average time until a system fails again after repair.
For example, if a system has an MTBF of 100 hours and an MTTR of 2 hours, the MTTF would be 102 hours.
