Backup is data. Recovery is a system.
Recovery includes people, access, documentation, dependencies, clean infrastructure, time and a sequence that someone can follow under pressure. A backup file is only one input to that system.
This is why a successful backup job can coexist with a failed recovery. The data may be incomplete, inaccessible to the incident team, dependent on a missing service, or simply too slow to restore inside the time the business can tolerate.
Test one real path
Do not wait for the incident to discover the restore procedure. Pick one representative file, database or service. Restore it into a safe location. Verify the result and record the elapsed time, permissions and hidden dependencies.
The first test does not need to be dramatic. It needs to turn “we have backups” into evidence that a specific recovery path works.
