A business continuity plan and a disaster recovery plan get used as if they mean the same thing. They do not — and the difference decides whether your business can keep taking orders while your IT is being fixed.
- A business continuity plan keeps the business operating during a disruption. A disaster recovery plan restores the IT systems. You need both, and they answer different questions.
- Disaster recovery is a component of business continuity, not a synonym for it.
- Continuity is owned by the business — people, processes, suppliers, customers. Recovery is owned by IT — systems, data, infrastructure.
- The two numbers that matter are how long you can operate without a system and how much data you can afford to lose — everything else follows.
- A plan nobody has tested is not a plan. Regular drills are what separate a document from a capability.
What a business continuity plan actually is
A business continuity plan sets out how the whole organisation keeps delivering essential services during a disruption — not just its IT. It starts with your critical business functions: the few things that, if they stop, the business stops — taking orders, invoicing, paying staff.
A business impact analysis tells you which functions are genuinely critical rather than guessing. From there the plan documents who does what, how you communicate in an emergency, and the manual workarounds that keep work moving while restoring the systems behind them. The scope is the entire business — which is why business continuity is not an IT document.
What a disaster recovery plan actually is
A disaster recovery plan is the narrower, technical counterpart — where restoring happens: restoring the affected systems, recovering the data, returning IT to normal. Where business continuity asks “how do we keep trading?”, disaster recovery asks “how do we get the systems back?”
It is owned by IT — your team or your provider — as technical recovery actions against defined recovery objectives: which servers come back first, where the clean backups are, how you fail over. The point people miss: disaster recovery is part of business continuity, not an alternative. Restoring the machines says nothing about how you keep invoicing while that restoring runs.
Business continuity vs disaster recovery: the differences that matter
The clearest way to hold business continuity and disaster recovery apart is to picture disaster recovery sitting inside business continuity: continuity is the outer ring keeping the business trading, recovery is the core restoring underneath it.
Line up business continuity vs disaster recovery and the split is clean on every dimension — scope, owner, timing, success measure:
| Business continuity plan | Disaster recovery plan | |
|---|---|---|
| Question it answers | How do we keep operating? | How do we restore the systems? |
| Scope | The entire organisation | IT systems and data |
| Owner | Business leadership, cross-functional | IT team or IT provider |
| Covers | People, processes, suppliers, premises, communications | Servers, data, backups, infrastructure |
| Timing | Proactive and during the event | After the incident |
| Typical output | Operational procedures, manual workarounds | Technical recovery actions, restore runbooks |
| Success measure | Business tolerance for disruption | Technical recovery targets |
The same disruption looks different through each plan — here is how business continuity and disaster recovery split three IT emergencies, from ransomware attacks to power outages and natural disasters:
The two numbers to decide first
Before any technology decision, settle two numbers. They come from the business, not IT — and everything else (backup frequency, failover, whether a manual workaround will do) follows.
RTO · Recovery Time Objective
How long a system can be down before the damage is unacceptable.RPO · Recovery Point Objective
How much data you can afford to lose, measured as time since the last good backup. An overnight backup means a one-day RPO; hourly backups shrink that to an hour.An owner can set both without a consultant: for each critical function, ask how long it can stop and how much data you could re-enter by hand. Those answers drive the plan.
What goes in an SMB plan (and what you can leave out)
An SMB plan need not look like an enterprise standard — a 60-page corporate framework is why most get written once and never opened. Keep it to what you would reach for at 8am on a bad morning:
- Roles and responsibilities, with a deputy for each
- Contact tree — staff, suppliers and key customers
- The critical function list from your business impact analysis
- Data and backup arrangements — what, how often, where
- Manual workarounds for each critical function
- A communication plan for staff, customers and suppliers
- Technical recovery steps — or who runs them
- A review date and testing cadence
Ageing hardware belongs on the risk list too: an out-of-support server is a continuity risk, not just an IT one, worth handling the way you would plan it as a project. Backup and disaster recovery hosting sits behind that data-and-backup line — the infrastructure your recovery objectives depend on.
A plan you have not tested is not a plan
The most common failure is not the absence of a plan — it is a plan nobody has tested. Backups that report success every night can still fail to produce a working system when you actually restore them. A documented recovery procedure reads perfectly until its author is on leave and someone else must run it under pressure.
This is why regular drills matter: restore-testing your backups rather than assuming they work. A business continuity and disaster recovery capability is proven by restoring, not documentation — where managed IT services earn their keep, testing the restore on a schedule so the first real recovery is not the first attempt.
“The first time we test a new client’s restore, it rarely comes back clean. The backups were running — but nobody had ever rebuilt a working system from them, and that is a very different thing.”— PIP, from onboarding restore tests
