Backups vs. disaster recovery: what's the difference?

"We have backups" might be the most dangerous sentence in small-business IT — because it usually ends the conversation right before the important questions get asked.

A backup is a copy of your data. Disaster recovery (DR) is your ability to get the business running again after something breaks — ransomware, a dead server, a flooded office, a deleted mailbox. One is a thing you have; the other is a thing you can do.

Two questions that matter more than "do we have backups?"

1. How much work can we afford to lose? If your last good backup is from last night, a failure at 4 PM costs you a full day of invoices, emails, and changes. The technical name is RPO (recovery point objective); the plain version is "how far back do we fall?"
2. How long can we afford to be down? Having the data is not the same as being operational. Restoring servers, reinstalling applications, reconnecting staff — without a plan, "we have the files" can still mean a week of downtime. That's RTO (recovery time objective): "how long until we're working again?"

Where "we have backups" quietly fails

• The restore was never tested. A backup you've never restored is a hope, not a plan. Many businesses discover corrupt or incomplete backups on the worst possible day.
• The backup lives next to the original. If your only copy sits on the same network — or the same building — ransomware and disasters take both at once.
• Ransomware encrypts backups too. Modern attacks deliberately seek out and destroy connected backups before they trigger. Offline or immutable copies are what survive.
• Nobody owns the plan. Who declares the emergency? Who calls whom? In which order do systems come back? If that lives in one person's head, your plan has a single point of failure.

What good actually looks like

The classic 3-2-1 rule still holds: three copies of your data, on two different types of storage, with one copy offsite (and ideally immutable). Add scheduled test restores — actually bringing files and systems back — and a short, written runbook that names owners and order of recovery. That's the difference between an IT incident and a business crisis.
