Backups are often seen as the safety net.
When systems fail, files are lost, or incidents happen, the assumption is usually simple: restore the backup and move on.

But having backups is not the same as having reliable backups.
In this week’s comic, the team discovers that part of their backup data was corrupted during recovery. The backups existed, but they could not fully restore what was needed.

That is where backup integrity becomes important.

What backup integrity really means
Backup integrity is the ability to trust that backup data is complete, accurate, and usable when recovery is needed.

A backup is not truly reliable unless it can:
• restore properly
• recover the expected data
• function when systems are under pressure

Problems like corruption, incomplete backups, failed jobs, or configuration issues may not be noticed until recovery is attempted. That is why testing matters.

Why it matters
Organizations rely on backups during:
• ransomware incidents
• accidental deletion
• outages
• hardware failures
• disaster recovery situations

If backups fail during recovery, the impact can become much worse.

Recovery testing helps teams confirm:
• data can be restored correctly
• backup systems are functioning properly
• recovery timelines are realistic
• critical information is actually protected

In cybersecurity, preparation is not only about creating backups. It is also about verifying they work.

Everyday takeaway
A backup is only useful if it can actually be restored when needed.
Testing backups may not feel urgent during normal operations, but recovery is not the time to discover something is missing or corrupted.
Because in security, confidence is not enough. Verification matters too.
