A backup is only useful if you can restore it.

A successful backup job is one piece of evidence. A recovery rehearsal checks whether you can actually recover the data or service you need.

Before the test

• Select a representative backup and record its timestamp.
• Define what success means: files readable, application starts, or a complete service recovery.
• Confirm you have the required keys, credentials, software and recovery instructions.
• Choose a separate restore destination with enough space.
• Keep restored services isolated so they cannot duplicate production IP addresses, send notifications or run scheduled jobs against live systems.

During the restore

• Use a new destination; avoid overwriting production data.
• Record the start time, restore size and any warnings.
• Check representative files and application data, rather than just whether the restore task completed.
• Test dependent services within the agreed isolated environment.

Compare recovery with your needs

Record how long recovery took and how much recent data was missing. Compare these observations with the recovery time and recovery point targets agreed for the service.

Close the loop

• Document the exact steps and anything that required improvisation.
• Resolve missing credentials or unclear recovery instructions.
• Remove test copies according to your data retention requirements.
• Schedule another rehearsal after material infrastructure or backup changes.

A simple test record

Service / dataset:
Backup timestamp:
Restore destination:
Isolation checks:
Start / finish time:
Validation performed:
Result / follow-up actions:

Keep this record alongside the recovery procedure so the next person has both instructions and evidence.
