Business Continuity and Disaster Recovery: Protecting Your Business from Operational Disruptions

The Cost of Business Disruption: Why Continuity Planning Matters

The Business Continuity Institute defines business continuity management as a discipline that safeguards an organization's revenue-generating activities, customer relationships, reputation, and brand. When a disruption hits, the questions that matter most are practical: can we still serve our customers, can our staff still work, and how long before normal operations resume?

The operational and financial impact

According to ENISA, fewer than one in five SMEs has a formal, documented business continuity plan. For the majority that do not, a serious disruption carries significant financial and operational exposure.

When systems go down, the impact compounds quickly. Revenue stops, customer-facing operations stall, and staff cannot do their jobs. The direct financial losses — lost revenue, emergency recovery costs, contractual penalties — are immediate and measurable. The indirect damage, to reputation, to client trust, and to the leadership time consumed by managing the crisis, often outlasts the technical disruption itself.

A business continuity plan does not prevent incidents from happening. It limits how far the damage spreads and how fast the organization can get back on its feet. That difference, between a managed disruption and a prolonged crisis, is what makes continuity planning one of the highest-return investments a company can make.

The regulatory dimension

For financial entities and their critical service providers, DORA (Article 11) makes business continuity a formal legal requirement with explicit senior management accountability. That is the clearest sector-specific obligation.

For other organizations, the regulatory driver is more indirect but still real. GDPR requires breach notification within 72 hours of discovering an incident. Meeting that deadline is only possible if a response structure already exists. Larger clients increasingly ask about continuity planning as part of supplier due diligence, and cyber insurers factor BCP maturity into premiums and coverage terms.

Business Continuity Plan vs. Disaster Recovery Plan: What Is the Difference?

These two terms are often used interchangeably. They address different problems, involve different people, and require different types of decisions. Understanding the distinction is the first step to building plans that actually work when you need them.

At a high level, business continuity is a leadership concern. Disaster recovery is a technical one. Both are critical to business resilience.

A Business Continuity Plan is a governance document with established protocols and prevention and recovery systems in the case of a cyberattack, natural disaster, or other business disruption. Its job is to keep critical operations running during a disruption, covering people, processes, and communications.

A Disaster Recovery Plan is a technical document. Its job is to restore IT systems and data after a disruptive event, in the right order and within defined timeframes. It lives primarily with the IT and security team, who are responsible for executing it under pressure.

BCPs and DRPs are complementary. ANSSI, the French national cybersecurity agency, describes them as crisis management (the business response) and incident response (the technical recovery). Both need to be in place and coordinated across an organization.

What a Business Continuity Plan (BCP) Should Include

Starting with the right questions

The UK Government's Business Continuity Management Toolkit, developed by the Cabinet Office and designed specifically for small and medium-sized organizations, defines BCM as identifying the parts of your organization you cannot afford to lose, such as information, stock, premises, and staff, and planning how to maintain them if an incident occurs. It frames the starting point as four questions:

1. What are your organization's key products and services?
2. What are the critical activities and resources required to deliver these?
3. What are the risks to those critical activities?
4. How will you maintain them in the event of a disruption?

The toolkit is explicit that BCM requires full senior management support from the outset. Without it, it is virtually impossible to instill a sense of value and ownership across the rest of the workforce.

The Cabinet Office toolkit also notes that plans must be kept on and off site. A plan stored only on your company network is unavailable precisely when you need it most.

The people dimension

Key-person dependency is one of the most common BCP failures. If only one person knows how to run a critical process, that knowledge needs to be documented and at least one backup person trained — so that if they are unavailable, the process can still continue.

In many small and mid-sized companies, the same person covers both cybersecurity and business continuity. That is a reasonable starting point, but BCP and DRP cannot be a one-person exercise. Both plans need active involvement from across the leadership team — operations, finance, communications — because when a crisis hits, the response has to be coordinated across the whole organization, not directed by a single individual.

Awareness and training

Business continuity planning must be part of the culture of your organization, achieved through raising awareness and training. All employees should understand why continuity matters, know their role in a crisis, and be familiar with communication protocols before an incident occurs. It is also important that as new employees are onboarded, they are also briefed on business continuity.

Cyber awareness training fits directly into this as well. Human error remains one of the leading causes of the incidents that trigger continuity. An organization that invests in training its people reduces both the likelihood of disruption and the chaos that follows.

What a Disaster Recovery Plan (DRP) Should Include

Where a BCP addresses the whole organization, a DRP focuses specifically on IT systems and data. It is the technical playbook your IT and security team follows during a crisis.

A DRP should cover every scenario that could take systems offline: ransomware, hardware failure, power outage, or natural disaster. The goal is not to anticipate every possible event but to ensure that when something serious happens, the path to recovery is already mapped.

Knowing what needs to be restored, and in what order

The starting point for any DRP is understanding which systems are critical to the business and what the cost of losing them looks like. Not all systems are equal, and trying to restore everything at once is a recipe for restoring nothing quickly.

A useful exercise is to map your key systems against the business impact of their unavailability and for different periods. Systems worth assessing include:

• Customer-facing platforms and e-commerce
• ERP and order management systems
• Email and internal communications
• Financial and accounting software
• CRM and customer data
• File storage and document management
• Authentication and access management

The goal is a clear priority order, informed by the operational and financial cost of each system being down.

The backup question most companies get wrong

Backups are the foundation of any DRP, but they are also one of the most common points of failure. Many organizations only discover their backups are incomplete, corrupted, or simply not restorable when they need them most — mid-incident, under pressure.

Having a backup is not enough. It needs to be tested regularly, with an actual restoration, not just a check that the backup process ran. A backup that has never been restored is an assumption, not a guarantee.

The other principle worth following is maintaining multiple copies. A sound approach is the 3-2-1 rule: three copies of your data, on two different media types, with one stored offsite or in an isolated environment. For organizations exposed to ransomware, this matters even more — a sophisticated attack will often target backup systems before encrypting live data, precisely to eliminate the recovery option. Immutable backups, which cannot be altered or deleted even by someone with administrative access, address this directly.

Testing Your BCP and DRP: Why Untested Plans Fail

Business continuity plans are not ready to use until they have been tested. Testing is the only way to find out whether your business continuity and disaster recovery plans are ready to respond to an incident.

Ideally, you would have a schedule of weekly, monthly and yearly tests that can keep your plans up to date as your business and employees change.

ANSSI, which co-published a dedicated guide in France on running cyber crisis exercises, recommends that each time your crisis team is activated, either or a real incident or for a tabletop exercise, there should be a structured debrief. You can discuss the lessons that were learned so you can modify your recovery plan accordingly. A well-managed crisis, and a well-run exercise, is an opportunity to strengthen your organization's resilience.

Building Cyber Resilience: A Leadership Priority

Business continuity and disaster recovery are not IT projects. They are business decisions about how much disruption your organization can tolerate, what recovery would actually require, and what you are prepared to invest to reduce that exposure.

For most SMEs and mid-sized companies, the gap between having no plan and having a workable one is smaller than it appears. It starts with identifying what your business cannot afford to lose — its critical processes, systems, and people. From there, it means documenting what happens when something goes wrong, ensuring the right people are involved across leadership and IT, keeping plans accessible and current, and testing them regularly — backups included.

The worst time to build these plans is after something has gone wrong.
