Hello Alester,
www.Linux-Backup.net has lots of tips, scripts and useful information.

Can you be more specific?
I'm not sure exactly what admin rights you have, but here is a script that gives you tape usage info.
The following commands are pumped into nsradmin to obtain the raw tape drive usage data:

 show name; NSR operation; statistics
 print nsr device

The following nsradmin session shows the output of these commands:

$ /usr/sbin/nsradmin
Networker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> show name; NSR operation; statistics
nsradmin> print nsr device
name: /dev/rmt/0cbn;
NSR operation: Write;
  statistics: elapsed = 2460, errors = 0, last rate = 923,
  max clients = 4, file marks = 6, rewinds = 0,
  files skipped = 24, records skipped = 0,
  current file = 19, current record = 223,
  seek files = 2, seek records = 0,
  estimated kb = 0, amount kb = 23808,
  file amount kb = 23808, sessions = 4;

Also, here is another link with a vast list of scripts to use.  There is one that will create a log report showing usage, etc.
