Not true. If you use tar as your backup program rather than dump, amanda
is quite happy to do backups of chunks of a filesystem rather than the
whole filesystem. This is the solution I'd go with if I were you.

Mhmm, is it possible to tell amanda/tar not to backup directorywise but
let's say 5% of the amount of data?

No, it's by directories, plus/minus include and exclude lists.

- Dividing the tape library into 25 tapes for RAID and 5 tapes for
HOMES - Every two weeks the whole RAID is backuped while the HOMES
get backuped daily
Problems: Amanda can not stripe a FS over multiple tapes, the tapes

Not true as of amanda 2.5.0, released yesterday (and in testing for a long
time).

I was referring to the FAQ from the amanda page where the opposite was
claimed. Good to know that this information is deprecated.

The mailing list and new wiki are a wealth of information.

Good luck.
