Business Continuity vs Disaster Recovery Explained
By A. Northam • Published: 2 March 2026 • Updated: 2 March 2026
Business Continuity (BC) and Disaster Recovery (DR) are closely related — but they are not the same.
In simple terms: BC is about keeping the business functioning. DR is about restoring technology after disruption.
What is Business Continuity (BC)?
Business Continuity is the planning and capability to keep critical business operations running during disruptions.
BC focuses on business processes, people, communications, and workarounds — not only technology.
Examples of BC decisions:
- How to continue customer support if systems are degraded
- How billing, payroll, or order fulfillment continues during outages
- How leadership communicates internally and externally during disruption
- Which services must remain available, and which can be paused
What is Disaster Recovery (DR)?
Disaster Recovery is the set of processes and capabilities used to restore IT systems, data, and services after a major disruption.
DR is often associated with backups, recovery sites, rebuild procedures, and tested restoration plans.
Examples of DR activities:
- Restoring systems from clean backups
- Failing over to secondary systems or environments
- Rebuilding compromised systems from known-good images
- Recovering data and validating integrity after restoration
BC vs DR: the core difference
- Business Continuity = operational continuity (people + processes + communications + priorities)
- Disaster Recovery = technical recovery (systems + data + services)
BC plans may include DR, but BC is broader.
RTO and RPO (two key recovery targets)
BC/DR planning often uses two common targets:
- RTO (Recovery Time Objective) — how quickly a service must be restored
- RPO (Recovery Point Objective) — how much data loss is acceptable (measured in time)
Example: An RPO of 4 hours means the organization can tolerate losing up to 4 hours of recent data, depending on backup/recovery design.
How BC/DR connects to security
BC and DR are often discussed in operational resilience, but they are tightly connected to digital security because many security incidents cause disruption:
- Ransomware and destructive malware can disable systems
- Credential compromise can lead to service disruption
- DDoS can directly impact availability

Testing and rehearsal
BC/DR plans that are never tested tend to fail under real pressure.
Common rehearsal methods:
- Tabletop exercises (scenario walkthroughs)
- Partial restores (prove backups are usable)
- Failover testing (where safe and appropriate)
- Post-incident reviews and plan updates
Common misconceptions
- Backups are not a BC plan. Backups support DR. BC includes people and process continuity.
- DR is not only for “natural disasters”. Cyber incidents are a major DR driver.
- Having a plan is not the same as having capability. Capability is proven by testing.
Key takeaway
Business Continuity keeps critical operations running through disruption. Disaster Recovery restores systems and data after disruption.
Mature organizations treat BC/DR as a continuous program — tested, measured, and updated over time.
