Contingency planning establishes communication systems, recovery thresholds, and employee roles and responsibilities to prepare for disasters. Disaster recovery plans provide step-by-step procedures for recovering critical systems after natural disasters like fires or human-caused incidents like cyber attacks. An effective plan identifies recovery teams, actions, and procedures to allow essential functions to continue operating and eventually restore regular services. It also includes off-site backups, training, risk analysis, and communication strategies to facilitate rapid response and recovery.
