Redundancy: The duplication of critical components or systems in order to provide backup in the event of a failure or outage. Redundancy is used in disaster recovery planning and business continuity planning to ensure that critical systems and functions can continue to operate in the event of a disaster. Examples of redundancy include having multiple servers, having backup power generators, and implementing data backups.
