•
Labeling and rotation of the tapes.
Use a tape handling routine that is easy to follow. Use a tape
labeling routine that assures you can find the correct tape for a
particular day and for the files needed. Use a tape rotation
strategy that provides for several generations of files and server
configuration backups, and for periodic off-site storage.
Maintaining Tape
Drives
Tape drives must be cleaned regularly with a cleaning cartridge to
maintain the integrity of your backup data. If you installed the
HP SureStore tape drive, clean them as advised in the “Cleaning”
section in the electronic
User’s Guide
on the
HP SureStore Tape
CD-ROM
that accompanies your HP tape drive. If your
HP SureStore DAT drive was preinstalled, use the instructions in
this section.
Recommended Cleaning Frequency
CAUTION!
❏
You should also clean the tape heads if the media caution signal
(flashing amber Clean light) is displayed on the tape drive.
Cleaning Cartridges
CAUTION!
❏
Use only an HP cleaning cartridge to clean the tape heads.
Do not use swabs or other means of cleaning the heads.
The cleaning cartridge uses a special tape to clean the tape heads.
A cleaning cartridge can only be used 50 times or as instructed on
the cartridge packaging. When the cartridge runs out of tape,
discard it and use a new one.
Cleaning Procedure
1. Insert a cleaning cartridge into the tape drive. The drive
automatically loads the cartridge and cleans the heads.
The cartridge ejects at the end of the cleaning cycle,
approximately 30 to 60 seconds. If the cartridge ejects in less
than 20 seconds, it has probably expired. In this case discard it
and repeat this step with a new cartridge.
2. Remove the cleaning cartridge from the tape drive and mark it
with the number of times it has now been used.
