DX-Series System

The DX-Series system solves these problems by separating the backup
target (servers) from the backup archive (tape libraries). The DX-Series
system takes advantage of high speed hard drives to greatly reduce the
time required for backup/restore functions and also improve confidence
in completing the backup in the time allowed. The data stored on the
DX-Series system can then be migrated to a tape library without utilizing
valuable network resources.
The DX-Series system consists of the DX30 and DX100 devices. Both are
backup devices based upon high speed disk drives instead of tape drives.
