ExaGrid vs IBM

ExaGrid Systems, Inc. is a disk-based backup hardware company that was founded in 2002 and is headquartered in Westborough, Massachusetts, with several satellite offices throughout the United States, Europe and Asia. The company serves customers in a variety of major industry sectors. The ExaGrid system is a turn-key disk backup with data deduplication appliance that works with existing backup applications. ExaGrid combines the use of compression and byte-level data deduplication to minimize the amount of data stored. This works by using standard data compression for the most recent backups, along with saving only byte-level changes from backup to backup for all previous backups. This approach can reduce the disk space required for disk-based backup storage by 20 to 1.
