I's still running 2.4.2p2 and use GNU tar to back up
subdirectories since the filer volumes are larger than
a tape, and some of the directories are not worth backing
up at all (temp space, web caches, duplicated data, etc.)

Nothing special, just entries like:
amanda1.hoovers.com /mnt/filer/home/lib   high-tar
amanda1.hoovers.com /mnt/filer/home/local high-tar

I use tar, subdirectories, and exclude lists to make
reasonably-sized pieces to backup.
