On the same tape?  For dependability reasons, amanda won't do that 
because she has no way of knowing when next restarted, where on the 
tape and how much of it has been used.  In between sessions, 
someone may have ejected the tape and re-inserted it, which would 
rewind it.  If amanda then does an incremental on the same tape as 
your only full, the full is over-written and lost.  Not a pleasant 
scene with the boss if you should need to do a full recovery 3 
hours after that incremental was done.

Tape is cheap when compared to the cost of lost data and the cost of 
regenerating that lost data from scratch.

Consider if the lost data is your only full, uptodate copy of your 
accounts receivable...  Buy the tapes.
