Why Companies look at VTLs

Backup jobs not

completing?

Tape drive utilisation low?

Tape drive quality

problems?

Aggressive recovery time

objectives (RTO)?

High operating costs of

nearline infrastructure?

… But Tape is Still Important

Best economy of scale

Best medium for long term archiving

Most energy efficient way of storing data

Less error prone than disk

52% of disk & tape users plan to increase

tape usage*

13% decrease of disk only systems in 2007*

58% of disk only users plan to start using
