Session Description: In the past year, data deduplication technology has conclusively moved out of the “emerging technology” category to become one of the most rapidly adopted technologies in the IT space. The onslaught of new vendors and their offerings have added a layer of confusion at the same time that opportunities for use of the technology have migrated far beyond its original role as a backup technology. This session takes a practical look at what’s possible to achieve with data deduplication and how users can best approach applying it in their environments.
