Disaster recovery (DR) is the set of policies, tools, and procedures that enable an organization to restore critical systems, data, and operations following a disruptive event. The term covers a wide spectrum of incidents: natural disasters such as floods and earthquakes, technology failures including server crashes and ransomware attacks, human errors, and deliberate sabotage. What unites these events is their capacity to interrupt the normal functioning of an organization and cause measurable harm.
A common misconception is that disaster recovery and business continuity are the same discipline. They are related but distinct. Business continuity planning (BCP) focuses on keeping essential functions running during a disruption, while disaster recovery focuses specifically on restoring technology systems and data after a disruption has occurred. In practice, the two programs work together: BCP defines what must keep operating, and DR defines how to bring systems back online to support those operations.
Disaster recovery planning sits within a broader organizational resilience strategy. Senior leadership, IT departments, operations teams, legal counsel, and human resources all have roles in shaping and executing a DR program. Without cross-functional ownership, recovery plans tend to be technically sound but organizationally incomplete, failing at the moment they are needed most.
Organizations of all sizes need DR planning. A small professional services firm losing access to its client database for three days faces a different scale of impact than a regional bank losing payment processing capability, but both face real consequences. The principles of DR planning scale to fit the organization's complexity, risk profile, and regulatory environment.
Requirement: ISO 22301 (Business Continuity Management Systems)
ISO 22301 is the international standard that specifies requirements for planning, establishing, implementing, operating, monitoring, reviewing, maintaining, and continually improving a documented management system to protect against, reduce the likelihood of, and ensure recovery from disruptive incidents. Organizations seeking certification must demonstrate that their DR and BCP programs are integrated, tested, and governed at the executive level. Compliance with ISO 22301 signals to regulators, clients, and partners that resilience is treated as a strategic management function rather than a technical afterthought.
- Disaster recovery restores systems and data after a disruptive event; it differs from business continuity, which focuses on keeping functions running during disruption.
- DR planning requires cross-functional ownership across IT, operations, legal, HR, and leadership.
- DR principles scale to organizations of all sizes and risk profiles.
- ISO 22301 provides the international governance framework for integrated business continuity and disaster recovery management.
