The purpose of an IT disaster recovery plan is to ensure that an organization can quickly restore operations following a disruptive incident, such as a data breach or natural disaster. This plan outlines the procedures for recovering critical systems, data, and applications while minimizing downtime and loss. It typically includes strategies for data backup, system redundancy, and communication protocols. By having a well-defined disaster recovery plan, organizations can safeguard against financial losses, protect their reputation, and maintain business continuity during crises.
