Production data deleted

What this means

Stop new writes before they overwrite recoverable history or make reconciliation harder. Your best recovery point may be a snapshot, point-in-time restore, replica, object version, export, or provider recovery feature.

Restore into a separate environment first. A backup is not proven until you can open it, check it, and reconcile it with activity after the recovery point.

Warning signs

• Record counts, storage usage, or customer files drop unexpectedly.
• The application returns missing-record, foreign-key, or empty-state errors.
• An administrator reports a destructive query, migration, import, or cleanup job.
• Audit logs show deletion from an unknown user or automation.
• A backup job says “successful,” but no recent restore has been tested.

Recover now

First 15 minutes

1. Stop destructive activity. Disable the responsible job, deployment, user, API key, or write path. If needed, put the application into read-only or maintenance mode.
2. Record the deletion window. Note the first bad result, last known good result, recent releases, jobs, queries, and people with access.
3. Preserve evidence. Export database, cloud, application, deployment, and identity logs before retention windows expire.
4. Protect remaining copies. Snapshot the current damaged system, replicas, volumes, and available recovery points. Do not promote or modify a replica before understanding its state.
5. Find the newest safe recovery point. Check point-in-time recovery, snapshots, exports, object versions, replicas, and provider support.

Today

1. Restore the selected recovery point into a new isolated environment.
2. Validate schema, record counts, recent customers, financial totals, file references, and application behavior.
3. Reconstruct activity after the recovery point from queues, payment records, emails, analytics, webhooks, event logs, and customer reports.
4. Choose a cutover plan. Decide whether to replace production, merge recovered records, or replay missing events.
5. Keep the damaged system read-only until reconciliation is complete.
6. If deletion may be malicious, rotate affected credentials and investigate connected systems before reopening writes.
7. Tell customers what is confirmed, what may be missing, and what they should avoid repeating.

Verify recovery

• Critical record counts and financial totals match independent records.
• Recent customer actions have been replayed or explicitly identified as missing.
• The application can read and write without integrity errors.
• The destructive identity, query, job, or deployment no longer has access.
• A fresh backup completes and restores successfully in a test environment.
• Monitoring detects another sudden deletion or record-count change.

Prepare now

Recovery

• Point-in-time recovery or versioning is enabled for critical production data.
• At least one backup copy cannot be deleted with normal production credentials.
• Retention covers the longest likely time before a deletion is discovered.
• Restore instructions include schema, files, secrets, queues, and external records.

Safety

• Production deletion requires a separate role, confirmation, or approval.
• Destructive migrations and cleanup jobs are tested against production-like data.
• Audit logs identify who deleted data and are retained outside the database.
• Important totals and record counts trigger anomaly alerts.

Practice

• A recent drill restored production-like data into a clean environment and measured the recovery time.

Common mistakes

• Continuing normal writes. New activity makes point-in-time recovery and reconciliation harder.
• Restoring directly over production. You lose the damaged state and your chance to compare.
• Trusting a successful backup job. Completion does not prove the data is usable.
• Recovering the database but not files. Database rows and object storage must agree.
• Ignoring post-backup activity. A clean restore can still lose recent orders or customer changes.
