A database restore rehearsal for an AI-built MVP
A restore rehearsal proves that a backup can recreate a usable application in an isolated environment. Restore a known dataset, connect a compatible app version, verify important records and permissions, and measure the time required. Record what data would be lost between the backup and the incident.
A database backup and an application rollback solve different problems. Reverting code does not recreate deleted records, and restoring old data can discard valid writes made afterward. This worksheet is for a rehearsal using synthetic data or an approved protected backup, never a surprise overwrite of production.
Put it into practice
1. Define the recovery target
List the app version, schema version, backup timestamp and critical workflows. Set business tolerances for recovery time and potential data loss before the exercise, rather than deciding whether the result is acceptable afterward.
2. Create an isolated destination
Use a separate database and environment. Disable outbound email, billing and other real-world side effects. Ensure the restored application cannot accidentally contact production integrations.
3. Restore with the provider's procedure
Use the backup format and restore process supported by your database host. Preserve the command or runbook, exit status and elapsed time. A downloaded backup file is not evidence of a successful restore.
4. Verify representative records
Check record counts, important relationships and a sample of known values. Sign in as the test roles and complete a critical workflow. Include uploaded files if they live outside the database.
5. Document the recovery decision
Compare the result with your recovery targets. Identify any external objects, secrets or migrations missing from the backup. Assign each gap an owner and repeat the affected step after fixing it.
Rehearsal evidence
Copy this structure into your review document and record your observed result for each row.
| Check | Record | Pass condition |
|---|---|---|
| Backup identity | Timestamp and format | Known source |
| Restore | Start, finish, status | No unexplained errors |
| Relationships | Sample parent and child IDs | References remain valid |
| Application | Version and smoke test | Critical workflow works |
| External files | Sample file references | Required files accessible |
A failure worth checking
A restored database can pass a row-count check while the app still fails because file storage, encryption keys or the matching schema version are absent. Include these dependencies in the recovery inventory rather than treating the database as the entire product.
Common questions
Should I restore over production to test it?
No. Rehearse in an isolated destination with controlled side effects. A real recovery requires its own explicit operational decision.
Is an automatic backup enough?
It is useful, but recovery confidence comes from a successful restore and application verification.
