Backup basics that actually work.

Most small businesses have backups. Far fewer have backups that actually restore. Here's the 3-2-1 rule and the test that separates real from theater.

Almost every business we meet has backups. Far fewer have backups that actually work when it matters. A backup you've never tested is a theory — and during a ransomware event, theories don't restore files. The discipline here is simple but unforgiving.

The 3-2-1 rule, updated

Three copies of your data. Two different storage types (local disk plus cloud, for example). One copy offline or in a separate account an attacker can't reach from your network. Modern ransomware specifically hunts backup servers — if your only backup lives on the same domain as your file server, attackers will wipe both before encrypting.

What typically fails

A property management company had nightly backups running for four years.

Red flag: Nobody checked the logs. They'd silently failed nine months prior. When ransomware hit, the most recent good backup was almost a year old.

A medical practice relied on a single NAS sitting next to their server in a closet.

Red flag: Attackers reached the NAS from the same network and erased it alongside encrypting the server. No offsite copy existed.

The test that separates real from theater

Once a quarter, pick a random folder and restore it to a test location. Time how long it takes. Confirm the files open. If the restore fails, if it takes eight hours, if the files are corrupt — you've found the problem on a Tuesday afternoon instead of during a crisis. Write the test date on a calendar.

Want us to audit your backups?

We'll verify your backups, test a restore, and tell you exactly where the gaps are. One session, no sales pitch.

Do this today
  • 1Confirm today: when did your last backup actually complete successfully?
  • 2Make sure one backup copy lives offline or in a separate cloud account your network can't reach.
  • 3Block a Saturday this quarter and restore a real folder to prove it works.
  • 4Put someone in charge of checking backup reports weekly. It's a 5-minute job.
  • 5Document your RTO (how fast you need to be back) and RPO (how much data loss is acceptable).
