The main purpose of a disaster recovery plan is to ensure that an organization can continue operating and providing critical services in the event of a major disruption or disaster. An effective disaster recovery plan outlines procedures and resources needed to minimize downtime and recover from loss of data, infrastructure, staff and facilities.
Quick Answer: The purpose of a disaster recovery plan is to provide a documented process for recovering critical systems, data, infrastructure and staffing after a disaster or disruption.
A comprehensive disaster recovery plan typically contains the following key components:
Business Impact Analysis
A business impact analysis (BIA) identifies and prioritizes the organization’s critical business functions and services. The BIA determines the potential impacts resulting from disruptions and outage timeframes that can be tolerated for critical systems and processes. This enables disaster recovery planners to focus efforts on the systems and resources that are essential for keeping the organization functioning.
Recovery Strategies
The disaster recovery plan outlines detailed strategies for recovering critical systems, data, hardware, communications networks, facilities and other vital assets. This includes restoring IT systems at an alternate location if the primary site is not accessible. Potential recovery strategies include backups, redundant infrastructure, alternative work locations, supplier agreements and other means of restoring functionality after a disruption.
Response Procedures
Documented response procedures outline the immediate actions to be taken following a disruption. This includes protocols for assessing damage, assembling the response team, activating recovery plans and communicating to stakeholders. Quick and effective initial response helps mitigate downtime and confusion during the first hours after an incident.
Implementation Plan
A step-by-step implementation plan details the sequence for recovering infrastructure, systems, applications, data and business processes. It defines responsibilities, tasks and timeframes for restoration. Prioritizing the recovery of critical assets enables the business to resume the most essential operations quickly.
Testing and Exercises
Frequent testing of the disaster recovery plan identifies vulnerabilities, ensures readiness and maintains an optimal state of recovery preparedness. Various testing methods include walkthroughs, simulations and full-scale exercises that validate the effectiveness of the plan.
Maintenance Procedures
Procedures should be established for maintaining and updating the disaster recovery plan. A schedule should be put in place for reviewing and distributing any changes to the plan. This ensures the plan stays current as the organization’s infrastructure, systems and business objectives evolve.
Staff Training
Personnel with defined disaster recovery roles and responsibilities should receive regular training on emergency response and recovery procedures. This prepares staff to act quickly and effectively when the disaster recovery plan is activated.
The Key Benefits of a Disaster Recovery Plan Include:
- Minimizes disruption of critical operations and services.
- Provides a framework for an organized response.
- Restores infrastructure and systems rapidly.
- Protects data and minimizes data loss.
- Reduces potential financial losses.
- Maintains customer and stakeholder confidence.
- Fulfills legal, regulatory and compliance requirements.
- Protects the reputation and brand image of the organization.
An Example Disaster Recovery Plan Outline
While disaster recovery plans are tailored to the individual organization, they follow a common high-level structure:
1. Executive Summary
Briefly summarizes the purpose and key elements of the disaster recovery plan.
2. Business Impact Analysis
Identifies critical business functions, processes and systems and analyzes the impacts of potential disruptions.
3. Risk Assessment
Assesses the types of disasters most likely to occur and their potential impact and damage level.
4. Recovery Strategies
Defines approaches for restoring infrastructure, IT systems, data and business operations after a disruption.
5. Response Procedures and Implementation Plan
Documents processes for responding to a disaster event and detailed steps for executing the recovery strategies.
6. Roles and Responsibilities
Defines disaster recovery roles, responsibilities and teams.
7. Communication Process
Outlines communication plans for status updates to internal and external stakeholders.
8. Testing and Exercises
Provides ongoing plan validation through simulations and tests.
9. Plan Maintenance
Establishes a process for regular disaster recovery plan reviews, updates and distributions.
10. Appendices
Includes information resources to support disaster recovery procedures, such as system inventories, equipment details, contact lists, floor plans and recovery site details.
Disaster Recovery Plan Maintenance
Proper maintenance ensures a disaster recovery plan remains current and operational. Plan maintenance entails:
- Regular reviews – Review the plan at least annually and update as needed. Include impacted departments in reviews.
- Change management – Update the plan to reflect changes to business processes, IT systems, operations, staff and business objectives.
- Version control – Manage plan revisions and provide updates to stakeholders. Retain superseded versions.
- Distribution – Provide plan access to all personnel with defined disaster recovery responsibilities.
- Audit compliance – Verify plan meets regulatory requirements and organizational compliance policies.
Testing the Disaster Recovery Plan
Testing is essential for maintaining a viable disaster recovery plan and preparation. Different types of plan testing include:
Walkthroughs
Team members walk through recovery procedures verbally to validate effectiveness and identify gaps.
Checklists
Validate recovery steps outlined in the plan against operational checklists used during actual recovery efforts.
Simulations
Partial or full-scale operational simulations to test disaster response and recovery procedures.
Parallel testing
Execute recovery operations on duplicate test systems in a parallel environment to avoid disruption.
Full interruption testing
Shift operations from the primary to the secondary recovery site for a period of time to validate recovery capabilities.
Component testing
Test the recovery of specific systems and infrastructure components.
Creating a Disaster Recovery Culture
Beyond a documented plan, effective disaster recovery requires an organizational culture that supports business continuity. Characteristics of a strong DR culture include:
- Regular awareness training for staff on the disaster recovery plan and procedures.
- Incorporating business continuity into workplace processes and behaviors.
- Alignment between disaster recovery objectives and broader business goals.
- Commitment from leadership to provide sufficient resources for disaster recovery capabilities.
- Understanding individual roles and responsibilities for restoring operations.
- Willingness to implement and periodically test disaster recovery plans.
- Embedding redundancy and resilience into infrastructure and application architectures.
- Collaboration across teams and departments to meet recovery objectives.
Key Disaster Recovery Planning Best Practices
Organizations should follow these best practices when developing and implementing a disaster recovery plan:
- Perform a business impact analysis to identify critical systems and acceptable outage times.
- Secure executive sponsorship and funding for disaster recovery planning.
- Involve representatives from all business departments in the planning process.
- Conduct a risk assessment to determine likely disaster scenarios and exposures.
- Outline detailed recovery procedures for systems, networks, applications and data.
- Define roles and responsibilities for disaster response teams.
- Implement awareness training for personnel on their disaster recovery responsibilities.
- Test the plan frequently via simulations, drills and exercises.
- Include disaster recovery in the business continuity management program.
- Update the plan regularly and distribute changes to stakeholders.
Conclusion
A comprehensive and tested disaster recovery plan is essential for managing risk, ensuring resilience and minimizing disruption to operations in the event of an emergency or disaster. The plan provides step-by-step procedures for responding to incidents and recovering critical infrastructure and systems. Maintaining and testing the plan improves readiness while embedding disaster recovery in the organization’s culture helps drive successful execution during disruptive events.
