How do I know if my company's backup really works?
A backup is reliable only when there is evidence that jobs complete successfully, copies are isolated from the production environment and representative restorations have been tested. Check scope, frequency, retention, encryption, access controls and the date and result of the latest restore test.
Risks to review
- Assume that a completed-job message proves the data can be restored.
- Keep every copy under the same credentials or in the same environment.
- Rely on synchronization that also replicates deletions or encryption.
- Have no documented owner or measured recovery time.
Safe recommendations
- List the systems, data and cloud services that must be protected.
- Verify frequency, retention and whether failed jobs generate alerts.
- Separate at least one copy from production credentials and infrastructure.
- Test a representative restore and record its duration and result.
- Define who reviews backup health and who authorizes recovery.
- Repeat tests after major infrastructure or application changes.
When to seek specialized help
- There is no recent evidence of restoration.
- Copies share accounts or access with protected systems.
- It is not clear what would happen if the server, provider, or an account fails.
