Redundancy for data and logs needs to be consistent with the organization's data retention plan and continuity of operations plan. ” “ [d]uplication of system components (e.g., hard drives), information (e.g., backup tapes, archived files), or personnel intended to increase the reliability of service and/or decrease the risk of information loss. ” General[edit | edit source] Redundancy is “ [t]he existence of more than one means for accomplishing a given function. Each means of accomplishing the function need not necessarily be identical. ” Technology[edit | edit source] Redundancy refers to “ [a] [r]epetition of parts or subsystems to assure operation if original (primary) part or subsystem fails. ” “ additional or alternative systems, sub-systems, assets, or processes that maintain a degree of overall functionality in case of loss or failure of another system, sub-system, asset, or process. ” References[edit | edit source] ↑ NISTIR 7628, Vol. 1, at B-2 n.34. ↑ Practices for Securing Critical Information Assets, Glossary, at 57. ↑ Department of the Army, Supervisory Control and Data Acquisition (SCADA) Systems for Command, Control, Communications, Computer, Intelligence, Surveillance, and Reconnaissance (C4ISR) Facilities, at B-4 (Jan. 21, 2006) (full-text). ↑ Department of Defense, Glossary of Defense Acquisition Acronyms and Terms (14th ed.
