The Incredibly Shrinking Backup Window
Data Domain of Palo Alto, CA, is one of a new breed of storage startups that are aggressively campaigning against tape-based backups. In fact, the company gives away car bumper stickers saying, “Tape Sucks, Move On.”
Its marquee product, the DD400 enterprise series falls loosely in the “Capacity Optimized Storage” (COS) category. The basic idea is to not waste storage space by holding the same email attachment or document copy multiple times. Instead, pointers are used to replace redundant copies so that only one or two need to be stored. Further, the backup data stream is adjusted so that maximum data flows in the smallest possible unit of time.
“The compression and filtering technology built into the DD400 series reduces backups by an average of 20 times,” says Bart Bartlett, director of marketing at Data Domain.
