Mean Time to Recover (MTTR)
What is Mean Time to Recover (MTTR)?
Mean Time to Recover is a metric that measures the average time it takes to restore a service or system to normal operation after a failure or incident. It is used to understand resilience, improve recovery processes, and reduce downtime when something goes wrong.
Examples
- After a ransomware incident, a team measures how long it took to rebuild systems and restore critical services from backups.
- An operations team tracks MTTR for failed web services to see whether monitoring and response improvements are reducing downtime.

Some metrics tell you how often systems fail. Mean Time to Recover tells you what happens next. It measures how quickly a team can get back to normal after a disruption.
This matters because outages and incidents are not judged only by the fact that they happened. They are also judged by how long the business was affected. A short disruption can be manageable. A long one can become expensive, damaging, and highly visible.
Summary 📝
Mean Time to Recover measures how long it takes on average to restore a service after a failure or incident. It is a key resilience metric because it reflects not just the health of the technology, but the readiness of the people, processes, and recovery design around it. Lower MTTR usually comes from strong monitoring, clear response ownership, tested recovery procedures, and architectures built for fast restoration.
