The benefits of deduplication and where you should dedupe your data

To identify duplicates, data can be examined in different ways depending on the technology used. For example, file-level dedupe—also called single-instance storage(SIS)—will identify identical files, store a single copy and replace subsequent identical copies with a pointer to the unique version stored. Examples of file-level deduplication include Novell Inc.’s GroupWise and Microsoft Corp.’s Exchange (although SIS isn’t supported in Exchange 2010) email programs. EMC Corp. also provides file-level deduplication on its storage arrays, including Clariion, Celerra and its new VNX series.
