Backups Are Not Disaster Recovery (And the Difference Could Save Your Business)

Here's something we hear all the time from small business owners: "We're backed up, so we're fine." And they usually are backed up — OneDrive is syncing, maybe there's an external hard drive plugged into the server, or their IT person set up some kind of cloud backup a few years ago.

But when we ask the follow-up question — "If your entire system went down right now, how long would it take to get back to work?" — the room goes quiet.

What's the Actual Difference?

Backup is a copy of your files, emails, and data stored somewhere separate from your main system. If a file gets deleted or corrupted, you can restore it. That's the extent of what backup does.

Disaster recovery (DR) is the full plan for getting your business back online after a major incident — ransomware, hardware failure, fire, flood, or a catastrophic cloud outage. It covers not just your data, but your applications, your email, your phone system, your team's ability to work.

Think of it this way: backup is the lifeboat. Disaster recovery is the plan that tells everyone where to go, what to do, and how to get the ship moving again.

Why Backups Alone Aren't Enough

We've seen businesses with perfectly good backups that still lost days of work after an incident. Here's why:

1. You Can't Restore What You Can't Access

If your backup is on a NAS drive on the same network as your server, ransomware will encrypt both. We've seen this happen — a business had daily backups running to a network-attached drive, but when ransomware hit, it encrypted the backup along with everything else. The backup was worthless.

2. Restoring Data Takes Time

Even with a clean, working backup, restoring 500GB of data from the cloud doesn't happen instantly. Depending on your internet speed and the amount of data, a full restore can take 24 to 48 hours. That's one to two days of your team sitting around unable to work. For some businesses, that's tens of thousands of pounds in lost revenue.

3. Data Isn't Everything

Your files are restored — great. But what about your applications? Your email server configuration? Your CRM settings? Your team's device configurations? Backup typically covers data, not the infrastructure around it. Without a recovery plan for the whole environment, you're rebuilding from scratch.

4. Nobody's Tested It

The most dangerous backup is one that's never been tested. We regularly find businesses whose backups have been silently failing for months. The daily email confirmation says "backup complete," but nobody has ever tried to actually restore from it. When the time comes, they discover the backup is incomplete, corrupted, or missing entirely.

What a Proper Disaster Recovery Plan Looks Like

A disaster recovery plan doesn't need to be a 50-page document. For a small business, it needs to answer five questions:

1. What are we protecting? Email, files, line-of-business applications, CRM data, financial records. List everything your team needs to do their job.

2. How quickly do we need to recover? This is your Recovery Time Objective (RTO). Can you afford to be down for an hour? A day? A week? The answer determines what kind of backup and recovery infrastructure you need.

3. How much data can we afford to lose? This is your Recovery Point Objective (RPO). If your last backup was 24 hours ago, you're losing a day's work. If it was 15 minutes ago, you're losing 15 minutes. The tighter the RPO, the more frequently you need to back up.

4. Where are our backups, and are they safe? Backups should be offsite (not on the same network), immutable (ransomware can't encrypt or delete them), and tested regularly. The 3-2-1 rule is a good baseline: three copies of your data, on two different types of storage, with one copy offsite.

5. Who does what when something goes wrong? Your team needs to know who to call, what to do immediately (don't turn off the server, don't try to fix it yourself), and how they'll keep working while systems are being restored. This is the part most businesses skip entirely.

The Cost of Not Having a Plan

The Federation of Small Businesses estimates that the average cost of a major IT incident for a small business in the UK is over £10,000 — and that's before you factor in lost clients, reputational damage, and the stress of rebuilding.

A disaster recovery plan doesn't eliminate the risk of something going wrong. It eliminates the chaos that follows when it does.

What We Set Up for Our Clients

When we onboard a new managed IT client, disaster recovery is one of the first things we configure:

• Independent backup of Microsoft 365 data (email, OneDrive, SharePoint, Teams) — not just sync, proper backup with point-in-time restore
• Immutable offsite storage that ransomware can't reach or encrypt
• Automated daily backups with monitoring and alerts if anything fails
• Tested restores on a regular schedule — we actually restore files to verify the backup works
• A documented recovery plan your team can follow, with clear steps and contacts
• RPO and RTO targets agreed upfront so you know exactly what to expect

It's not glamorous work. But it's the work that means a ransomware attack is a bad afternoon, not a business-ending event.

Want to know where you actually stand? We offer a free backup audit — we'll check what's being backed up, whether it's recoverable, and what's missing. No sales pitch, just a clear picture of your risk.
