Backups and all that (was: missing libncurses.so.5 and other lib*)

Actually I have been meaning to ask: what exactly do you backup?
Everybody and every doc says "backup the important stuff", but what
exactly in the system is important? Currently I backup the following:

/boot/loader.conf
/etc
/usr/X11R6/etc
/usr/local/etc
/usr/local/share/config
/var/db/pkg
/home/<user>
/root

Is this sufficient?
