Moritz, I'm guessing you did not read or fail to appreciate that amanda
never does a level 0 of everything at the same time.  If you do daily
backup runs, and want a weekly level 0 of all your data, amanda will
nominally backup 1/7 of your 600 GB each day.  Plus incrementals
of everything else.  Even if your data is not compressible, you should
have no trouble fitting the data onto a single magazine of 120GB.

OTOH, if you mean to do a level 0 of everything, everytime you backup,
then "never mind".  Forget my comments.
