I know that the FAQ says to just use dump to make backups but what if

across OSs and file system types? Is there any more-or-less universal
format?
tar(1) with gzip(1).
Re Amanda: for me, its likely too complex since I only have two boxes
and one is a desktop only. Right now it runs its own backup script to
create a tarball then the main box rsyncs that over to it.
see? works fine.
Amanda basically does that, without using ssh and without some kind of
security (this may have changed recently). It also keeps a reference
database for which file is stored on which tape, and a index on each
tape of the contents.
Well, right now, I just do full backups. Incrementals get rather
tedius. Especially since they find new files but they don't notice a
file that has been deleted. So I don't need a list of what files are in
which tarball but rather just what date it is. A simple log: this tape,
this date, this tarball.
All in all, pretty smart design. The best thing out of the features
AMANDA provides is this tidbit: everything is in gtar to keep things
as a standard.
As long as the archive format that it tells tar to use is compatible
with whatever version of tar you go to use in 20 years; but that's
another topic.
Thanks,
Doug.
