A disaster recovery plan is a documented process to recover IT infrastructure and systems after a natural or human-induced disaster. The goal is to restore technology services and computer systems as quickly and smoothly as possible to avoid disrupting critical business operations.
Why is a disaster recovery plan important for an organization?
A disaster recovery plan is crucial for minimizing disruption and financial loss in the event of a disaster. Without a plan, it can take weeks or months to restore systems, resulting in significant downtime that impacts business productivity and revenue. A robust plan helps an organization respond efficiently to get technology services functioning again.
A disaster recovery plan is important because it:
- Minimizes downtime when a disaster occurs
- Prevents data loss and ensures backups are intact
- Facilitates a quick and orderly restoration of systems
- Reduces potential financial losses from outages
- Maintains compliance with industry regulations
- Protects critical infrastructure and IT assets
- Maintains the reputation and brand image of the company
Without a plan, the organization risks going out of business if a disaster destroys its infrastructure and interrupts operations for an extended period. A disaster recovery plan demonstrates due diligence and preparedness.
Who is responsible for creating and maintaining the disaster recovery plan?
The disaster recovery plan is usually created by a team of individuals in an organization, often led by the Chief Information Officer (CIO) or IT Director. Key team members involved can include:
- Business managers and application owners
- IT infrastructure staff
- Data center staff
- Security staff
- Communications staff
- Risk management staff
- Operations staff
It’s critical to involve both IT staff and business leaders in the planning process. This ensures the plan reflects the needs and requirements across the organization.
Once created, maintaining and updating the disaster recovery plan is an ongoing process. The plan should be reviewed and tested frequently, such as annually or biannually. The tests assess the plan’s effectiveness and look for gaps or areas of improvement. IT leaders are often accountable for facilitating regular plan updates and working with stakeholders to test procedures.
What are the key elements included in a disaster recovery plan?
A comprehensive disaster recovery plan will include the following key elements:
Emergency response procedures
The procedures outline immediate actions to take at the onset of a disaster, like shutting down equipment and evacuating employees from the affected site. This includes assembling a response team and notifying key stakeholders.
Impact analysis
An impact analysis evaluates the potential effects of a disaster, such as which systems, networks, and facilities will be impaired. This helps prioritize recovery actions.
Recovery strategies
The plan will define strategies to recover impaired systems and infrastructure. Common recovery strategies include data backups, alternative work sites, equipment replacement, and use of third party services.
Implementation plan
An implementation plan details the tactical steps to execute the recovery strategies. It specifies roles, responsibilities and procedures for restoring infrastructure, systems, data, and business operations in a step-by-step sequence.
Testing plan
Testing the plan with periodic exercises exposes gaps and weaknesses to improve the plan. The testing plan outlines the scope, frequency, and types of testing to validate the recovery strategies.
Maintenance schedule
The schedule outlines when to review and update the plan, including assigning responsibility for maintenance procedures. Plans should be updated at least annually or when significant system changes occur.
Contact information
The plan includes a complete call tree with contact details for internal team members, technology partners, vendors, and other external organizations that provide recovery support.
