Inventorying tape slots
It checks all the slots of the tape library to see if they are occupied and reads in media information
from all the tapes. The whole process may take a while, depending on the number of tapes and
the tape drive speed.
Erasing a tape
The quick-erasing function overwrites the tape header only. It takes much less time than erasing a
tape, which wipes out all data in the tape. To quick-erase or erase a tape, please click the radio
button in front of the slot and click the Quick Erase or Erase button.
Retensioning a tape
To retension a tape is to wind the tape evenly so that it is properly tensioned. Use this feature only
when there are errors accessing the tape. To retension a tape, please click the radio button in
front of the slot and click the Retension button.
Scanning a tape for backup indexes
If the backup index files are missing, the NAS server will not be able to restore the data. In this
case, please insert the tapes and scan them for backup indexes. The NAS server will copy the
backup indexes from the tapes. To scan a tape, please click the radio button in front of the slot
and click the Scan button.
Defining a Media Pool
A media pool is a group of tapes managed as a unit. You must define a media pool before
assigning any backup schedules.
To define a media pool, please go to the Backup ÆTape LibraryÆMedia Pool menu and click
New Pool.
