I want to backup my Linux system (with rsync).
What is recommended to backup and what not?

Of cause, all the personal stuff should be saved but what about the "normal" system
stuff of the OS?

Which of the files, dirs and settings should be backuped?

And the same question on what NOT to backup? Is there more to exclude than /proc?

Besides personal stuff, I also save /etc.

After I switched to Ubuntu, I try to keep manual changes to /etc
minimal and manage /etc with a "night script".

I also store some system files in /etc that I edit manually, under my
CVS, so I have a copy of them.

That way rebuilding of a system is very easy. I had a laptop die on
me, and rebuilding it was a breeze.

Definitely /etc, or at least the bits of it that you've customized.

Is one language more powerful than another? Compare, for example,
English with Yiddish. Sure, it's hard to describe a carburetor in
Yiddish, but try describing a schlemiel in English. (Stoll 1995)

I use BRU, not rsync, but the same results can be obtained with a
combination of _find_ and _cpio_. I have it do a full backup every night
when I am asleep.

I only exclude _core_ files. I back up the following file systems on my machine:

FILES="/ /boot /home /home/boinc /homeB /opt /usr /usr/local /usr/src /var
/mnt/valinuxl/etc /mnt/valinuxl/home"

You probably will not have all of these.

I happen to back up onto magnetic tape.

I find it easier to back up everything to one place than to have to reload
lots of disks, pick up updates from the Internet, sometimes from places that
no longer exist, etc.
