Did you possibly miss the "allow for individual CD browsing for specific
files" perhaps? Or maybe I was not clear: I would very much like to be
able to pop one cdrom of the set of backups into the drive and be able to
ls, cp and less (for example) the files on that particular cdrom. A few
pieces of tarball is not really what I'm looking for.

Thanks anyway

Ciao

Search for cddump. AFAIK, it is no longer maintained, but I'm using it
just fine.

No, but you didn't say how. With the --new-volume-script you could write
a script that outputs a file listing, which is then stored alongside the
archive.

Apparently, you weren't.

That is something completely different. It's rather easy to write a
small script for that. I've done such a thing for Perl once.

0: Y=1, X=the first file
1: Create a directory for CD Y if it doesn't exist
2: Take a look at the size of file X
3: Does it fit on CD Y?
4a: (yes) -> put it in dir for CD 1
4b: (no) -> increase Y and go to 1
5: Let X = the next file
6: Go to 1

The problem with the world is stupidity. Not saying there should be a
capital punishment for stupidity, but why don't we just take the
safety labels off of everything and let the problem solve itself?

Not quite the same, is it?

At least we cleared that up.

Thanks, the concept is simple. However I'd prefer a more robust solution
than I would be able to come up with in the n hours I could spend on
writing my own. Hence my original post.

Thanks anyways.

Writing your own programs can be just as robust or even better as/than
those built by someone else. Then again, I don't know your programming
skills

Eeps. Once again, de-contextualising my post doesn't do much
constructive. I can code fairly well, but to do anything reasonably
robustly will take time - and that is not something I have too much of
right now.
