I have 83 backups resulting to 130% of data. So a ratio of 63:1.
Nice.
But because of performance limitation I don't

I've used a similar (tho hand-cooked) script running `rsync`.

This may not be exactly what you want, but then again it may.
I've been looking at a program called Mondo which does most
of what you're talking about (and can span CD's, if one isn't
big enough, &c.). The homepage is

Hi,
I am looking for a cheap backup system for my machine. A recent scare
regarding my hard drive ("is it a 75GXP?") forced me to think about
backup policy.
I'd love to own a Jaz drive but at the moment I can't afford one.
However, I do have a CD-RW in my machine.
This is what I want to do in

am quite happy with it.

I use bru 2000 and I am _very_ happy with it.
I also us cpio to copy my whole filesystem(/) to a different partition

You could get by with cpio but I like the tape verify and features of bru
