amadmin has all sorts of neat reports. Check out the man pages.
For example:
amanda$ amadmin ds1 balance
due-date #fs orig KB out KB balance

I think the totals are the before and after compression sizes of
the planned level 0's for the next dumpcycle.
For individual file systems, see your "curinfo" dir. Under "host/filesys"
there should be a file named "info". The line beginning "stats: 0", eg.
stats: 0 635750 321824 208 1029397183 12 DS1-10
has the last uncompressed (635750KB) and compressed (321824) sizes.
You should be able to get them all with "grep '^stats: 0 ' curinfo/*/*/info"
