Business continuity and disaster recovery are closely related, but they are not interchangeable. The distinction is important because organisations can have a technically robust disaster recovery capability and still be unprepared to maintain critical services during a disruption.

Business continuity takes a broader, organisation-wide view of how critical activities, services and operations will continue or be recovered when disruption occurs, while disaster recovery typically focuses more narrowly on restoring technology, systems, infrastructure and data.

In practice, organisations generally need both. Business continuity establishes what the organisation needs to continue or recover, how quickly it needs to happen and what dependencies must be managed. Disaster recovery helps restore the technology and IT capability required to support those objectives.

The strongest approach is therefore not business continuity versus disaster recovery. It is business continuity supported by effective disaster recovery, integrated into a wider organisational resilience capability.

What Is Business Continuity?

Business continuity is an organisation’s capability to continue delivering critical products, services and activities during a disruption, or recover them within an acceptable timeframe.

It considers much more than technology. Effective continuity planning examines dependencies across:

• People and skills
• Processes and critical activities
• Facilities and equipment
• Suppliers and third parties
• Technology and information
• Utilities and telecommunications

A business continuity program will typically include a Business Impact Analysis to identify critical activities, the consequences of disruption, maximum tolerable periods of disruption, recovery priorities and required timeframes. These findings inform continuity strategies and Business Continuity Plans, including practical arrangements for maintaining or recovering critical operations.

Importantly, business continuity is not simply about producing a Business Continuity Plan. An effective program requires people to understand their roles, decision-makers to know when and how to escalate an incident, and recovery arrangements to be practical enough to work under pressure.

What Is Disaster Recovery?

Disaster recovery generally focuses on restoring technology and IT capability following an incident. 

Depending on the organisation, this can include the recovery of:

• IT infrastructure
• Applications and systems
• Networks and connectivity
• Servers and cloud environments
• Databases and data
• Technology platforms and services
• Backups and restoration capability

Two common measures used in disaster recovery are:

• Recovery Time Objective (RTO): the target timeframe for restoring a system or service following disruption.
• Recovery Point Objective (RPO): the acceptable amount of data loss, expressed in time. For example, an RPO of one hour means the organisation aims to recover data to a point no more than one hour before the disruption.

Disaster recovery arrangements may include backups, redundant infrastructure, alternative data centres, cloud environments, system restoration procedures and IT recovery teams. 

These capabilities are essential, but restoring technology does not necessarily mean that the business can immediately resume its critical services.

Business Continuity vs Disaster Recovery: Key Differences

Although business continuity and disaster recovery are closely related, they have different purposes, scopes and recovery priorities.

Ultimately, business continuity and disaster recovery should not operate in isolation. Business continuity defines what the organisation needs to recover and by when, while disaster recovery helps restore the technology required to achieve those objectives. Alignment between the two is essential to building practical organisational resilience.

How Business Continuity and Disaster Recovery Work Together

Business continuity and disaster recovery should not operate as separate silos. A Business Impact Analysis might determine that a particular customer service needs to be restored within four hours. That requirement should then inform the technology recovery arrangements supporting the service. 

If the application required to deliver that service has an eight-hour RTO, there is a clear misalignment. Similarly, an IT team may prioritise the recovery of a particular system because it is technically important, while the business considers another service more critical. 

Aligning business and technology recovery priorities ensures that disaster recovery supports the organisation’s most critical operational needs.

Business Continuity vs Disaster Recovery in Practice

The relationship between business continuity and disaster recovery becomes clear during a major disruption, such as a cyberattack that results in the loss of access to critical systems.

The disaster recovery response might involve:

• Isolating affected systems
• Restoring clean backups
• Rebuilding infrastructure
• Recovering applications and data
• Validating system integrity
• Returning technology services to operation

Those actions are essential, but they may not be enough to keep the organisation functioning while recovery takes place.

Business continuity arrangements may also need to address:

• Alternative ways for staff to perform critical processes
• Manual workarounds
• Staffing and resource constraints
• Customer and stakeholder communications
• Supplier coordination
• Alternative working arrangements
• Prioritisation of critical services
• Escalation and decision-making
• Regulatory or contractual obligations
• How services will operate while systems remain unavailable

The result is a coordinated response in which technology recovery supports business recovery.

Why a Disaster Recovery Plan Alone Isn’t Enough

Technology recovery is essential, but it is only one part of maintaining and restoring critical business services.

Disruptions can also result from:

• Loss of premises
• Staff shortages or loss of key personnel 
• Supply chain disruption
• Utility outages
• Cyber incidents
• Telecommunications failures
• Natural hazards
• Critical supplier failure

In each case, technology may continue to operate while the organisation’s ability to deliver critical services is compromised. For example, restoring an organisation’s core application may be technically successful, but if employees cannot access the workplace, key staff are absent or a critical supplier is unavailable, the business may still be unable to deliver its services.

The goal is not simply to restore systems, but to restore the organisation’s ability to deliver the services that matter most.

What Should a Business Continuity Framework Include?

A business continuity framework provides the structure for developing, maintaining and improving continuity capability across an organisation.

Depending on the organisation, this may include:

• Governance and responsibilities: clear ownership, accountability and decision-making authority.
• Business Impact Analysis: identification of critical activities, impacts, dependencies and recovery requirements.
• Risk and disruption scenarios: consideration of events that could affect critical operations.
• Continuity strategies: realistic approaches for maintaining or recovering critical activities.
• Business continuity plans: practical guidance covering roles, actions, communications, escalation and recovery.
• Crisis escalation arrangements: mechanisms for bringing strategic decision-makers into significant or escalating incidents.
• IT and disaster recovery alignment: ensuring technology recovery priorities support business requirements, including appropriate RTOs and RPOs.
• Exercises and testing: validating whether plans, roles and recovery arrangements work in practice.
• Review and continual improvement: updating arrangements as risks, services, technology and organisational dependencies change.

Where Does Crisis Management Fit?

Crisis management is closely related to both business continuity and disaster recovery, but each discipline has a different focus:

• Crisis Management: strategic leadership, decision-making, coordination and communication.
• Business Continuity: maintaining and recovering critical business activities and services.
• Disaster Recovery: restoring technology, systems, infrastructure and data.

These capabilities need to work together. A major cyber incident, for example, may require crisis leaders to make strategic decisions about customer communications and organisational priorities, business continuity teams to maintain critical services, and IT teams to recover affected systems.

Treating these capabilities as connected parts of a broader resilience framework helps avoid gaps between strategic decision-making, operational continuity and technical recovery.

Business Continuity and ISO 22301

ISO 22301 is the international standard for Business Continuity Management Systems. It provides a framework for establishing, implementing, maintaining and continually improving business continuity capability.

Importantly, mature continuity capability is about much more than creating a business continuity plan. It involves governance, Business Impact Analysis, risk assessment, continuity strategies, planning, exercising, performance evaluation and continual improvement.

In other words, business continuity is a management capability, not simply a document. 

Building an Integrated Organisational Resilience Capability

Business continuity, crisis management, emergency management and disaster recovery each address different aspects of disruption. Their value increases when they are coordinated and exercised as an integrated capability.

A major incident may require emergency management to protect people, crisis management to provide strategic leadership, business continuity to maintain critical services and disaster recovery to restore technology. The exact arrangements will depend on the organisation’s size, complexity, risks and operating environment. There is no single template that works for every business. What matters is understanding what is critical, identifying dependencies, agreeing on recovery priorities, assigning responsibilities and testing whether arrangements work in practice.

Frequently Asked Questions

Is business continuity the same as disaster recovery?

No. Business continuity is broader and focuses on maintaining and recovering critical organisational activities and services. Disaster recovery primarily focuses on restoring technology and IT capability.

What is the main difference between business continuity and disaster recovery?

Business continuity considers the organisation as a whole, while disaster recovery focuses primarily on technology, systems, infrastructure and data.

Is disaster recovery part of business continuity?

Disaster recovery can be an important component of a broader business continuity and organisational resilience capability. Technology recovery should support the business requirements identified through continuity planning.

Does every organisation need a business continuity plan?

Most organisations benefit from having defined arrangements for maintaining and recovering critical activities. The scale and formality of those arrangements should reflect the organisation’s risks, complexity and obligations.

What is a business continuity and disaster recovery plan?

A business continuity and disaster recovery plan refers to the documented arrangements an organisation has in place to prepare for, respond to and recover from disruption.

What is the difference between a Business Continuity Plan and a Disaster Recovery Plan?

A Business Continuity Plan sets out how critical business activities will be maintained or recovered during a disruption, including the people, processes, facilities and other dependencies involved. A Disaster Recovery Plan focuses primarily on restoring technology, systems, infrastructure and data needed to support those activities.

How often should business continuity and disaster recovery plans be tested?

Testing frequency should reflect the organisation’s risks, complexity and requirements. The important point is that plans should be exercised regularly enough to validate assumptions, maintain familiarity and identify improvements. Testing should include both business continuity exercises and appropriate technical recovery testing.

How does ISO 22301 relate to business continuity?

ISO 22301 provides an internationally recognised framework for managing business continuity. It guides organisations in establishing, implementing, maintaining and continually improving their Business Continuity Management System, including governance, analysis, planning, exercising and review.
