Backup & Recovery • Continuity
Backup testing: how often and why
Backups can “look fine” until the day you need a restore. Testing is what turns backups into real recovery. Here’s a practical testing schedule and what you should validate.
A simple testing schedule
Monthly
Restore a small set of files and confirm integrity + permissions.
Quarterly
Test a full system restore (or VM restore) and measure recovery time.
Twice per year
Disaster recovery run-through: outages, ransomware scenario, key systems priority.
After major changes
New server, migration, or cloud change? Re-test restores immediately.
What to validate during a restore test
- RTO: how quickly can you restore core operations?
- RPO: how much data could you lose between backups?
- Account access: can the right people log in after restore?
- Application functionality: do systems actually run, not just boot?
- Offsite safety: backups protected from ransomware and deletion.
Why “successful backup” reports can mislead
Backup software can report success even if: credentials changed, a repository is full, a restore chain is broken, or critical databases aren’t consistent. Testing catches these issues early.
