Backups should automatically spread across multiple tapes in case they
don't fit onto one tape. That's why we are using a tape changer.
In 2.4.X a single dump may not be larger than your tape capacity.
In 2.5.0 (currently in beta) that limitation is removed.
Hm, I cannot upgrade the software on the server until Etch is out
because I need a somewhat more stable and reliable state of things with
AMD64. An upgrade will screw up the server, and it's not a good idea to
try that now ... The system is still only a few days after the state of
Sarge, so an upgrade to Etch might be possible.
From what I've been reading, I was afraid it won't work and decided
to solve the problem once it occured.
Can I make entries in the disklist that do not represent mount points?
I could, for example, make seperate entries for some users who are
using a lot of disk space or even one for each user. But I would want
to keep an entry for /home so that I won't forget to make an entry in
the disklist for newly created users and have them in the backup
nonetheless.

Thanks! But tar -T doesn't work, I tried that out with a couple test

prometheus:/tmp/xxx#
Only the directory ./aa should have been included in the archive, but
tar cowardly includes everything, and ./aa even twice. Only excluding
(-X) works, but it doesn't work the other way round, either:
prometheus:/tmp/xxx# tar -cf test.tar --exclude "*" -T include .
prometheus:/tmp/xxx# tar -tvf test.tar
An empty archive is created by that, with no warning about contradictory
options. (It is imho rather questionable having the exclude option
override the explicit include option. That should be the other way
round.) Do the exclude and include options in the disklist or in the
dumptypes work otherwise?
To backup /home/[a-c]*, /home/[d-f]* etc., I would have to set up like
10 exclude files or so many disklist entries --- I just posted another
mail about it to the list because it doesn't have to do with the problem
of the dump sizes not corresponding to the allocated space.
Maybe I just have to try it out ... :/
