I find it useful to make a copy of /etc as there are bits of
customisation there, it's rarely very large so space isn't an issue,
just copy the whole lot.

If you have any databases (mysql etc.) they're in /var which can be a
bit of a pain to backup, but those databases aren't anywhere else.

Finally if you have any custom software additions in /usr/local you need
to back them up.

That's the way I do it when I want a good 'clean out'.
