Define acceptable loss and delay
Set the maximum tolerable data-loss window and recovery duration. Inventory databases, uploads, configuration and keys separately. Copying the web directory alone rarely restores a complete service. Use an application-consistent database backup method.
Separate copies and credentials
Keep backup copies outside the production instance with separate, least-privilege credentials. Choose retention, encryption and off-site storage deliberately. A mirror that propagates deletions should not be your only backup.
Restore in isolation
Recover a selected point in time onto a temporary instance. Check record counts, attachments, authentication and an end-to-end business operation. Prevent the test environment from emailing real customers or initiating payments.
Turn results into maintenance
Record actual restoration time, the recovered data timestamp and missing dependencies. Alert on capacity, failed jobs and stale copies. Remove temporary resources only after validation and apply the findings to the next scheduled backup.
