If you upgrade to Amanda 2.5.x, then you can instruct Amanda to split dumps
across tapes; so you can make your partitions as large as you like, and just
use as many tapes as are required.
AFAICT, this doesn't really split the tar but tries to create separate
tars of subdirectories. Unfortunately RMAN puts it all in one directory
(There may be a way to split it -- I'm checking into that too).
Is it possible to get amanda to follow symlinks? Every file name ends
in a digit is it is trivial to do something like:
rm /empty/GIS1/*
find /NFS/euphrates_backup/GIS -name '*[1,3,5,7,9]' -exec ln -sf {}
/empty/GIS1/ \;
rm /empty/GIS2/*
find /NFS/euphrates_backup/GIS -name '*[0,2,4,6,8]' -exec ln -sf {}
/empty/GIS2/ \;
Then backup GIS1 and GIS2 as separate volumes.
Would it be better to try this trick with hard links? RMAN needs to be
able to delete uneeded files after each run.
The tricky part of this path is that if you have a single large filesystem
(and a few smaller ones), the single large one will dominate your tape usage,
resulting in an unbalanced backup window.
