What is disaster recovery, and how is it different from backup?

Backup is a copy of your data, kept so it can be restored if the original is lost or damaged. Disaster recovery (DR) is a broader, more comprehensive plan and set of systems for getting your entire business back up and running, applications, servers, network access, not just the underlying data, after a major disruptive event. Backup is a critical ingredient of disaster recovery, but the two aren't the same thing, and confusing them leaves genuine gaps.

Where Backup Alone Falls Short

Having a backup of your data means you can restore the files themselves, but if your entire server infrastructure is destroyed (fire, theft, catastrophic hardware failure), having a backup file doesn't mean you have anywhere to restore it to, or the applications and configuration needed to make that data usable again quickly. Backup answers "can I get my data back." Disaster recovery answers "how quickly can my business actually be operational again."

The Two Numbers That Actually Define a DR Plan

• RTO (Recovery Time Objective), how long can your business tolerate being down before operations are restored? An hour, a day, a week, this varies enormously by business and by which specific system is affected
• RPO (Recovery Point Objective), how much data loss can you tolerate, measured in time? If your last backup was 24 hours before an incident, you've lost up to 24 hours of data created since, is that acceptable, or does it need to be closer to zero?

These two numbers, defined deliberately for your specific business and systems rather than left as an assumption, drive every other decision about what kind of backup frequency, replication, and recovery infrastructure you actually need.

What a Proper DR Plan Includes

• Replicated infrastructure, the ability to spin up critical systems in an alternate location (often cloud-based) if the primary site is unavailable
• Documented, tested recovery procedures, a clear, rehearsed process for restoring operations, not an assumption that "we'll figure it out" during an actual crisis
• Regular testing, actually practising a recovery, not just confirming backup jobs complete successfully, since a backup that can't actually be restored under pressure isn't a real safety net
• Prioritisation, a clear order of what gets restored first, since not every system is equally critical, and trying to restore everything simultaneously often means nothing gets restored efficiently

Cloud's Role in Modern DR

Cloud infrastructure has made robust disaster recovery genuinely accessible to SMEs in a way it simply wasn't when DR required maintaining a fully duplicated physical secondary site. Cloud-based DR lets you replicate critical systems to a geographically separate cloud region at a fraction of the cost of a traditional physical secondary data centre.

Testing Is the Step Most Often Skipped

The single most common gap in DR planning isn't the technology, it's the absence of regular, realistic testing. A DR plan that's never actually been exercised frequently has gaps that only surface during a genuine crisis, exactly when there's no room for surprises.

Our Approach

We use Veeam-based backup combined with proper disaster recovery planning, defining RTO and RPO deliberately for your specific systems rather than a generic default, and building in regular, realistic recovery testing so a DR plan is a genuinely proven capability, not just a document sitting unopened until the day it's actually needed.
