Disaster Recovery Exercise
A disaster recovery exercise is a planned test of people, procedures, and systems used to restore technology after a disruptive event.
In simple terms
The team practices restoration rather than assuming a backup will work when needed.
Technical explanation
Exercises may range from a walkthrough to an isolated restore or controlled failover. They should measure actual restoration time, recovered data point, dependencies, and defects, while protecting live customer activity.
An exercise should test actual steps, people, credentials, dependencies, and verification of recovered data. The measured result and discovered defects are more useful than a plan marked complete.
Examples in practice
An operations team restores a database backup into a separate environment, verifies record integrity, and records how long the process took.
A team restores a database into an isolated environment and finds that a missing key prevents the application from reading it. They fix key escrow and repeat the exercise.
Why it matters
A successful backup job does not prove the organization can recover a usable service within its target.
