Why Use Hierarchical Storage Management (HSM)

1.   Lower the cost of Data Storage

Typically 80-98% of data stored does not change - Optical and Tape Storage is much cheaper than Hard Disk

2.     Improve System Performance

Archiving old unchanging data from a hard disk to optical disk or tape improves overall system performance

3.     Reduce Backup Time

With HSM, reduced amounts of hard disk data are backed up.

Backup is faster and more efficient so increasing system availability
