e/Data redundancy

Information
has gloss	eng: Data redundancy, sometimes refers to in computer data storage, is a property of some disk arrays (most commonly in RAID systems) which provides fault tolerance, so that all or part of the data stored in the array can be recovered in the case of disk failure. The cost typically associated with providing this feature is a reduction of disk capacity available to the user, since the implementations require either a duplication of the entire data set, or an error-correcting code to be stored on the array.
