Diligent Technologies provided software that would enable companies to save backup data to disk instead of tape, which was the prevalent method. This would make it faster to back up and retrieve information. The company's flagship software was ProtecTIER, a "deduplication" product that would eliminate redundant data, such as in emails sent to multiple addresses, and reduce the amount of disk space needed by 25 times or more.

Exit: Diligent, originally spun off from EMC (NYSE: EMC) in 2002, was sold to IBM (NYSE: IBM) in April 2008.
