Your Backups Are Probably Broken — Here’s How We Test Restores

Here’s an uncomfortable truth from years of recovering data: a large share of the backups we inspect are broken, incomplete or unrestorable — and nobody knew until disaster struck. A backup you’ve never restored isn’t a backup. It’s a hope.

Why backups fail silently

• The job errored weeks ago but no one was alerted
• A database was backed up mid-write and the dump is inconsistent
• The backup only covered files, not the database (or vice versa)
• Retention quietly overwrote the only good copy
• The backup lived on the same server that failed

The 3-2-1 rule, in practice

We build to a simple standard: at least three copies of your data, on two different types of media, with one copy off-site. Off-site and encrypted is non-negotiable — it’s what protects you from ransomware and from the whole machine going up in smoke.

How we actually test restores

Verification is the part everyone skips. Our process:

1. Restore to an isolated environment on a schedule — not the production server.
2. For databases, restore the dump and run integrity checks against it.
3. Boot the application and confirm it actually works with the restored data.
4. Record the restore time, so your recovery objectives are based on reality, not guesswork.

Know your numbers

Testing restores also tells you your real RTO (how long recovery takes) and RPO (how much data you’d lose). Those two numbers should drive your backup design — not the other way around.

If you can’t remember the last time someone restored your backups and watched them work, treat that as a red flag worth fixing this week.
