Advanced Digital Information Corp. (ADIC) has accelerated its move away from its core tape business by acquiring Australian startup Rocksoft. (See ADIC Buys Rocksoft.)
The $63 million that ADIC paid for Rocksoft in a deal announced Tuesday night gives it de-duplication technology, which has been showing up in disk-backup products over the last several years. De-duping is a way to reduce the footprint and bandwidth required to store and transmit data. (See Data Compression: The Squeeze Is On!.)
ADIC corporate marketing director Steve Whitner says Rocksoft's technology will likely find its way into all of ADIC's disk products, with the Pathlight virtual tape library (VTL) "a perfect place to put this."
De-duplication -- also known as commonality factoring or single instancing -- compresses data that appears in more than one place, either before or while it's being read to disk. Diligent Technologies has used de-duplication software in its virtual tape libraries since last year, and Data Domain recently added a VTL product based on the de-duplication software it has sold on backup appliances since 2003. (See Data Domain Adds VTL Option.) Asigra and Avamar also use de-duplication in backup software.
What these de-duplication vendors have in common is a strong desire to drive a nail into the coffin of tape libraries, or at least reduce tape to an archiving medium. (See Diskers Enjoying Tape Woes.)
