Definition
Disaster Recovery is the process of restoring systems, services and data after a failure, security incident or other event that interrupts their operation.
Human Explanation
Disaster Recovery describes how an organisation will regain access to its systems and data following a serious disruption.
Why it Matters
The faster systems can be restored, the lower the potential operational, financial and reputational losses.
Conceptual Boundary
Disaster Recovery focuses primarily on IT infrastructure and services. It is one part of the broader Business Continuity system.
Practical Perspective
A Backup is not a recovery plan. The organisation must also verify that data and systems can actually be restored within the required time.
