Data De-duplication is a method of reducing storage needs by eliminating redundant data. Only one unique instance of the data is actually retained on storage media, such as disk or tape. Redundant data is replaced with a pointer to the unique data copy. For example, a typical e-mail system might contain 100 instances of the same one-megabyte file attachment. If the e-mail platform is backed up or archived, all 100 instances are saved, requiring 100 MB storage space. With data de-duplication, only one instance of the attachment is actually stored and each subsequent instance is referenced back to the original saved copy. In this example, a 100 MB storage demand could be reduced to only one MB.
