Use the correct media

Getting the most out of cartridges and drives

5.5

Getting the most out of cartridges and 
drives

Use mostly the matching media type (DAT 160 media for DAT 160, DAT 72 
media for DAT 72, DDS-4 media for DDS-4).

Use media for the recommended number of times (DAT 160, DAT 72 and 
DDS-4=100 full backups). Overuse of the tape will cause it to degrade and 
possibly shed tape debris in the drive. Too many new tapes can also cause 
wear of the drive as they are rougher than used ones.

Do not verify (DDS does read-after-write checking automatically).

Do not overload the server during backups. Maximize the transfer rate (run 
overnight with no other processes) and use incremental backups if conve-
nient.

Do not overuse your tape drive—it is designed for approximately three hours 
of tape pulling per day, not constant usage—and clean the drive regularly. 
See 

“Cleaning cartridges” on page 25

.

If you want to bulk erase cartridges, this should be done in a controlled 
environment. You need to make sure there are no other cartridges with 
sensitive information on them anywhere near the bulk eraser when in use. 
All data will be lost on cartridges that are bulk erased.
