Mean Time Between Failures (MTBF) indicates the average time between

Explanation:
Mean Time Between Failures measures how long a system operates between failures. It tells you the expected interval from one failure to the next in a repairable system, focusing on uptime between faults rather than the downtime needed to fix them. It’s not the time to repair (that’s MTTR), nor a count of faults per se, nor a measure of disaster recovery time. For example, if a machine runs 1,000 hours and experiences 5 failures, the MTBF is 200 hours. This metric helps plan maintenance and assess reliability when used alongside MTTR to gauge overall availability.
