Disaster Recovery Plan: What It Should Include

When an ERP system crashes at the end of the month, ransomware encrypts production files, or a power outage shuts down the data center, technology alone isn’t what makes the difference. What makes the difference is the disaster recovery plan—that is, the set of technical, organizational, and procedural decisions that enable the restoration of services, data, and infrastructure within timeframes consistent with the business’s acceptable risk level.

In structured organizations, the point is not simply to have a document on file, but to have a plan that can be activated, has been tested, and is aligned with actual operational priorities. This is particularly true for industrial settings, multi-site groups, regulated companies, and organizations subject to stringent contractual or insurance requirements. In these environments, the most common mistake is to view disaster recovery as the sole responsibility of IT. In reality, technical recovery is only part of the problem.

What Is a Disaster Recovery Plan, Really?

A disaster recovery plan defines how an organization restores its information systems, data, connectivity, and infrastructure components following an adverse event. Such events may include a cyber incident, a hardware failure, human error, a power outage, a physical incident at the site, or a disruption affecting critical suppliers.

The definition, however, needs to be clarified. A serious plan does not merely describe backups and replica servers. It must link technological assets to business processes, clarify who decides when to activate them, outline realistic recovery sequences, and establish criteria for resuming operations. Without this link, there is a risk of restoring infrastructure that does not return the company to acceptable operating conditions.

For this reason, disaster recovery is part of a broader framework of organizational resilience. Risk governance,business impact analysis, crisis management, supply chain dependencies, and regulatory requirements directly influence the quality of the plan.

What Should a Disaster Recovery Plan Include?

The design varies depending on the industry, the architecture, and the downtime tolerance, but certain elements are always required.

Clear and measurable restoration goals

Each plan must specify the RTO and RPO for critical services, applications, and datasets. Defining them in general terms is not enough. An RTO of four hours, for example, has different implications depending on whether it applies to corporate email, a plant’s MES, or a payment platform. These objectives must be approved by the business, not merely proposed by IT, because they reflect the level of operational and financial loss considered tolerable.

Scope, Priorities, and Dependencies

An effective plan distinguishes between mission-critical systems and those that are important but can be deferred. It also maps out dependencies that are often underestimated: digital identity, DNS, connectivity, privileged access, cloud services, telecommunications, third parties, support infrastructure, and physical site facilities. Many recovery efforts fail not because of a lack of backups, but because of an unaccounted-for dependency.

Roles, Responsibilities, and the Decision-Making Chain

A clear command structure is needed. Who declares the disaster? Who authorizes the failover? Who contacts the provider? Who approves the return to production? In a real-world scenario, ambiguity in decision-making causes delays and increases the damage. For this reason, the plan must specify escalation procedures, on-call schedules, delegated authority, and activation criteria.

Detailed Operating Procedures

Procedures must be easy to understand, organized in a logical sequence, and usable even under pressure. There is no need for encyclopedic manuals. What is needed are verifiable instructions, including prerequisites, commands, checks, decision points, and criteria for accepting the result. It is helpful to distinguish between technical runbooks, playbooks for specific scenarios, and coordination procedures.

Communication and Stakeholder Management

Recovery is not just a technical restoration. Customers, management, internal controls, insurers, strategic suppliers, and, in some cases, regulatory authorities must receive consistent and timely communications. The plan must therefore specify who communicates, what message is conveyed, and when. Delayed or contradictory communication can cause more reputational damage than the initial outage itself.

Disaster Recovery Plan andBusiness Continuity: The Difference Matters

In business terminology, the two terms are often used interchangeably, but the distinction is significant. Disaster recovery focuses on restoring technology, data, and ICT infrastructure. Business continuity ensures the continuity of critical processes, even when a full recovery is not yet possible.

This means that a company can have a good temporary business continuity plan and, at the same time, an inadequate disaster recovery plan. The opposite can also happen: a technically sound recovery plan that is unable to support business priorities. Aligning these two areas is one of the most challenging steps, especially in complex organizations with multiple functions, multiple sites, and distributed suppliers.

The Most Common Mistakes in Floor Plan Design

Real-world experience reveals specific patterns. The first mistake is to build a plan based on available technology rather than on the impact on the business. The second is assuming that backup is synonymous with recoverability. Having copies of the data does not guarantee acceptable recovery times, the integrity of configurations, or the availability of dependencies.

Another common mistake is the lack of realistic testing. Many organizations claim to have a plan, but have never validated the end-to-end execution of a credible scenario. There is also the issue of obsolescence: cloud environments, hybrid architectures, connected industrial assets, and application changes quickly render an unmanaged plan unreliable.

Finally, there is the issue of third parties. More and more recovery efforts rely on external providers, managed service providers, hyperscalers, telecom operators, or vertical-specific software companies. If these stakeholders are not included in the response model, the plan remains incomplete.

How to Develop a Credible Disaster Recovery Plan

Developing the plan requires a systematic approach. The process begins with an impact analysis, the classification of services, and the definition of acceptable outage thresholds. Only then are replication architectures, backup methods, alternative sites, cloud options, access segregation, and recovery orchestration solutions evaluated.

The design phase must then translate these decisions into an operational model. At this stage, it is helpful to involve not only IT infrastructure and cybersecurity teams, but also process owners, operations, compliance, procurement, physical security, and, if necessary, insurance departments. The reason is simple: the theoretical recovery time rarely matches the time that can actually be achieved in practice.

The level of detail must also be tailored. An organization with few core applications and standardized processes can adopt a relatively compact plan. An industrial group with OT, logistics, ERP, quality systems, and distributed sites will need plans tailored by scenario, technology, and geographic location. There is no one-size-fits-all solution.

The Role of Testing in a Disaster Recovery Plan

An untested plan is a hypothesis, not a capability. This principle—often cited but rarely put into practice—distinguishes mature programs from those that are purely documentary.

Which Tests Are Really Worth It?

The most useful tests are not necessarily the most spectacular. Well-designed tabletop exercises can highlight gaps in decision-making, a lack of accountability, or overlooked dependencies. Technical tests verify backups, replication, failover, and restore. Integrated tests, which are more challenging, check for consistency between the technical response, managerial coordination, and communication.

The choice depends on the level of maturity and the level of risk. In highly critical environments, it is advisable to adopt a phased approach, with differentiated scenarios and formal success criteria. The goal is not to prove that the plan always works, but to understand where it does not yet work.

What to Measure During Testing

It is necessary to measure actual times, deviations from RTO and RPO, decision quality, resource availability, the effectiveness of escalation procedures, and the completeness of documentation. The results must lead to corrective actions with defined ownership and deadlines. Without this step, the test remains merely a formality.

Standards, Governance, and Management Responsibility

A disaster recovery plan cannot be left solely to technical initiative. It requires managerial sponsorship, approval criteria, periodic reviews, and integration with the organization’srisk managementframework. International standards help precisely in this regard: they make the plan verifiable, comparable, and consistent with recognized practices.

For top management, the central issue is the proportionality of the investment. Not all applications warrant high availability or secondary sites in hot standby. In some cases, the cost of protection exceeds the plausible damage; in others, the opposite is true, and under-protection exposes the organization to unsustainable operational, contractual, and reputational losses. The right decision stems from a comprehensive assessment of impact, probability, dependencies, and compliance requirements.

From this perspective, a specialized partner like Continuitaly can help transform the plan from a technical document into a verifiable organizational capability through assessments, methodological design, specialized training, and tests structured in accordance with recognized international standards.

When the plan is ready

A disaster recovery plan can be considered mature when it does not rely on the memory of individuals, when target timelines are supported by evidence, when critical dependencies are known, and when management understands the financial and operational trade-offs of the decisions made. Maturity is not determined by the complexity of the document, but by the organization’s ability to carry out recovery under degraded conditions, with incomplete information, and under pressure.

This is where the difference between formal compliance and true resilience becomes apparent. A well-written plan is reassuring. A plan that has been designed, updated, and tested truly safeguards business continuity, reputation, and corporate value. The key question, therefore, is not whether the plan exists, but whether it could actually be implemented tomorrow morning.
