Testing Your Backups: Recovery Drills That Actually Work

A backup is only useful if you can restore from it when everything fails. Schedule regular recovery drills that go beyond verifying file integrity. Perform full bare-metal restores to isolated test environments and confirm that applications start correctly with expected configurations. Test database restores and verify data consistency with checksums or row counts. Measure your actual recovery time and compare it against your RTO targets. Rotate which systems you test each month so every critical workload gets validated over time. Keep a runbook that documents restore steps, dependencies, and contact information for application owners. After each drill, record what worked, what failed, and what you changed. Treat backup testing as a recurring operational task, not a one-time project.
