How often should a backup be tested?
A backup is only useful if it works when you really need it.
Yet many companies rarely, if ever, test their backups.
Yet many companies rarely, if ever, test their backups.
The reality in many companies
- Backups run automatically
- Errors go undetected
- Recovery is never practised
Result: In an emergency, the backup does not work as expected.
What are the risks?
- Incomplete data
- Excessively long recovery times
- Incompatible systems
- Loss of access
How often should testing be carried out?
Recommendation:
- At least once a quarter
- For critical systems: monthly
- After every major change (system, software, structure)
Best Practice: Realistic Tests
A test should be as close as possible to a real-life scenario:
- real data
- real systems
- timing of the recovery process
Backup without testing is a risk.
Only by testing regularly can you be sure that everything will work when it really matters.
Recommendation:
Schedule regular test cycles and document the results.
