If you're using hardware compression, yes.  But, in that case, you need to 
lie to amanda about how big your tapes are (i.e., don't set tapelenth to 
20GB (the native capacity), set it to something between 1 and 2X larger, 
depending upon how much your data compresses).

If you want to continue using software compression (let's amanda be more 
accurate), then turn off compression at your tape drive.

Priority -- it's all there in the amanda.conf.
