Business continuity vs disaster recovery: what's the difference?
Business continuity keeps the whole organisation running through a disruption; disaster recovery restores the IT systems and data underneath it. A plain-English guide to how they differ and fit together.
Business continuity is about keeping the whole organisation running through a disruption; disaster recovery is about restoring the IT systems and data underneath it. Disaster recovery is a part of business continuity, not a synonym for it, and treating them as the same thing leaves gaps that show up at the worst possible moment.
What is business continuity?
Business continuity (BC) is the organisation's ability to keep delivering its critical products and services, at an acceptable level, during and after a disruption. It's deliberately broad: it covers people, processes, facilities, suppliers and technology, and it includes the un-technical things, manual workarounds, alternative sites, communications, decision-making, that keep a business functioning when systems are degraded.
Business continuity is proactive and organisation-wide. Its home is a business continuity management system, and the international standard for that is ISO 22301.
What is disaster recovery?
Disaster recovery (DR) is narrower and more technical: it's the set of capabilities and procedures for restoring IT infrastructure, systems and data after an incident. Backups, failover, replication, rebuilding servers, recovering databases, this is DR.
Disaster recovery is reactive and technology-focused. It answers "how do we get the systems and data back", and it's usually measured with the same RTO and RPO objectives that continuity planning sets.
The difference, side by side
| Business continuity | Disaster recovery | |
|---|---|---|
| Scope | The whole organisation | IT systems and data |
| Covers | People, process, facilities, suppliers, tech | Backups, failover, restore |
| Stance | Proactive, keep operating | Reactive, restore what's lost |
| Question | How do we keep running? | How do we get the systems back? |
How they fit together
The cleanest way to think about it: disaster recovery is a component of business continuity. Business continuity is the umbrella that asks how the organisation survives a disruption; disaster recovery is the technology-recovery workstream inside it. You can have a brilliant DR capability, systems back in minutes, and still fail at continuity if your people don't know where to go, your suppliers are down, or no one can take orders while IT recovers. Equally, a continuity plan with no credible DR behind it is a plan that assumes the systems fix themselves.
So it isn't a choice between them. A mature organisation needs both: continuity to keep the business operating, and disaster recovery to restore the technology that most of the business now runs on. An ISO 22301 programme brings them together, with the recovery objectives from your business impact analysis driving both the business workarounds and the technical restore.
This is also why regulators stopped accepting a documented plan as proof of anything: DORA and NIS2 want to see continuity and recovery that have actually been tested. ResiliencePilot keeps both current and evidenced, from the BIA through to tested recovery. See the ISO 22301 solution or book a demo.
