Why must you test restores and not only take backups? Outline a simple validation routine.

Problem Statement

Explanation

Backups can be corrupt, incomplete, or incompatible. A restore is the proof that recovery works. Without tests, failures appear during incidents when time is scarce. Automate periodic restores to a sandbox, replay logs to a target timestamp, and run canary queries and row-count checks. Compare checksums or counts against baselines, and alert if validation fails. Record RTO and update runbooks.

Code Solution

SolutionRead Only

1) Restore latest full
2) Replay logs to T
3) run: SELECT COUNT(*) FROM critical_tables; -- compare to baseline
