In addition to what everyone else said, if you put a tape in the robot and do not do an inventory in NetBackup, when NetBackup attempts to mount the tape that it THINKS is there, it will read the header of the tape and realize that the media-id on the header of the tape doesn't match what it thinks is in the library, so it will freeze that tape and not use it. NetBackup does several checks to make sure it doesn't write over a tape that is not expired.

Subject: [Veritas-bu] NBU overwriting data on Tape
Hi
We are planning to move from TSM to NBU. We heard draw back that NBU can
accidently overwrite data on tape if tape library inventory is not run
after putting full tape in library.
If that is true, how can we avoide ?
Your help is very much appreciated.
