I use GNU tar exclusively for backing up my RS/6000's.... it supports
large block sizes, incremental dumps, stay-in-one-partition (good for
backing up / without everything under it), multi-volume archives, 
sparse file compression (good for databases), reading a list of files
to archive, volume labels, interactive processing, verification, 
reading a file that is a list of files to exclude, and compress-on-the-fly
(by doing a popen to compress(1))... among other things.  The distribution
also includes an implementation of rmt, the remote mag tape server.... 
I've not seen anything yet that comes close to it, especially for the price...
that and a couple shell scripts less than one screenful each, and I can
pop a tape in my Exabyte and leave, returning the next morning to 
find my five-system subnet all appropriately backed up and (with the
help of another program with appropriate SCSI calls) the tape 
out of the drive.
