(1) Hmm, I don't erase DVD+RW media before re-writing it, maybe that's a
difference with the -RW media? I've only done direct backups so far,
without compression. And no differentials at all (it's easy, and I can
mount them directly to pull files off of.)
I'm interested in what you find.
On the quantity of source code you seem to retrieve, do the projects use
cvsup? Sounds like a lot more work than there ought to be. :)
