Backup and Disaster Recovery for UK SMEs: What You Need to Know

Most UK small business owners use the words “backup” and “disaster recovery” interchangeably — but they describe very different things. Understanding the difference matters because backup and disaster recovery for UK SMEs isn’t just about copying files. It’s about being able to trade, serve clients, and pay staff after something goes wrong.

What’s the difference between backup and disaster recovery?

Backup protects your data. Disaster recovery protects your business’s ability to function.

A backup is a copy of your data — files, emails, databases — stored somewhere separate from the original. If a file is deleted or corrupted, you restore it from the backup. That’s the limit of what a backup does on its own. It doesn’t tell you how quickly your systems will be back online, who is responsible for restoring what, or whether the restore has ever been tested.

Disaster recovery is a broader plan that covers all of that. It defines what happens after a failure — a ransomware attack, a fire, a server failure, a major software error — and sets out how your business gets back to normal operation. Backups are a component of disaster recovery, but the plan is bigger than the backup.

What are RTO and RPO — and why do they matter?

RTO (Recovery Time Objective) is how long your business can survive being down before the damage becomes unacceptable. RPO (Recovery Point Objective) is how much data you can afford to lose — measured in time.

These two numbers should drive every decision about your backup and recovery setup. A business that backs up once a day has an RPO of 24 hours — meaning in a worst-case failure, you lose everything from the past 24 hours. Whether that’s acceptable depends entirely on your business. For an e-commerce company processing orders all day, it isn’t. For a small professional services firm that works from saved documents, it might be.

RTO works the same way. How long can you function without access to your email, your files, or your key systems? Two hours? Two days? That answer sets the standard your recovery plan needs to meet — and directly affects what it costs to deliver it.

What does a good backup and disaster recovery plan cover?

A solid plan for a UK SME should cover four areas: what is being backed up, where it is stored, how quickly it can be restored, and who is responsible for doing it.

In practice, that means:

• Regular, automated backups of all business-critical data — not just files, but also email, cloud data (Microsoft 365, Google Workspace), and any line-of-business applications.
• Offsite or cloud storage so a single incident at your office doesn’t destroy both the original and the backup. A backup kept on a USB drive in the same building as your server provides no protection against theft, flood, or fire.
• Tested restores — regularly. A backup that has never been restored is an assumption, not a guarantee. Your IT provider should be testing restores on a scheduled basis, not just assuming the files are there.
• A written recovery plan that names who does what, in what order, and how to reach them. When a crisis hits, no one should be working from memory.
• Defined RTO and RPO targets matched to your business, so your plan is actually designed to meet your recovery needs rather than just checking a box.

Does UK GDPR require a disaster recovery plan?

Not by name — but effectively yes. UK GDPR requires organisations to ensure “the ongoing availability and resilience of processing systems and services.” The Information Commissioner’s Office (ICO) expects businesses to have documented, tested technical and organisational measures to protect personal data. A business that loses client data and has no recovery plan is likely to be found lacking those measures.

If your business handles client data of any kind — and almost every UK SME does — a tested backup and disaster recovery plan is part of your GDPR obligations, not just good housekeeping.

What should your IT support provider be doing?

Backup and disaster recovery should be a core part of any managed IT support contract, not an optional add-on. Ask your current or prospective provider:

• What exactly is being backed up, and how often?
• Where are backups stored — and are they offsite or in the cloud?
• When did you last test a restore — and how long did it take?
• What are our RTO and RPO commitments?
• Is there a written disaster recovery plan, and have we reviewed it together?

If your provider can’t give clear answers to all five of those questions, that’s worth raising before something goes wrong rather than after. A good IT support partner treats recovery planning as an ongoing responsibility, not a one-time setup task.
