Despite the availability of multiple backup appliances supporting deduplication, Data Domain has continued to win customers at a steady pace. As of March 2009, the company had more than 2,900 customers and recruited hundreds of value added resellers. Its proven deduplication technology, integrated replication, and aggressive campaign to eliminate tape garnered it a tremendous amount of mind share and put it on most customers’ short lists. So it comes as no surprise that they were acquired by a major storage vendor.
That it was acquired by NetApp does come as a bit of surprise. NetApp does have its own successful VTL that supports deduplication. But then again, NetApp didn’t introduced deduplication in its VTL until the Fall of 2008 (the last of the major storage vendors to do so) and it typically sells its VTL into its own customer base. With Data Domain, NetApp now owns one of the toughest competitors in the backup appliance market and it gives the company a system that it (and the hundreds of NetApp channel partners around the globe) can sell into non-NetApp environments.
