If you put a TSM tape in a library that is now controlled by NBU, then 
yes, NBU will overwrite it because it has no knowledge of the TSM 
database.

Running an inventory isn't going to help in this situation, you will need 
to keep track of when TSM expires the tape so you can recycle it under 
NBU.

If NBU put the data on tape, then no, it won't be overwritten until the 
retention period has expired.
