Something that we do to get most of the configuration files backed up is:

# Create list of RPM config files that have changed
 > files_rpmconfig
rpm -qac --dump  | sed -e "/^(/d" | while read -a line
do
#	echo "Line: ${line[0]} ${line[3]}"
	if false
	then
		if [ ! -r ${line[0]} ]
		then
			echo "Unable to access file: ${line[0]}"
		fi
	fi
	if [ -f ${line[0]} ]
	then
		fi=(`md5sum ${line[0]}`)
#		echo "Sum: ${fi[0]}"
		if [ ${fi[0]} != ${line[3]} ]
		then
			echo "${line[0]}" >> files_rpmconfig
		fi
	fi
done

This should backup any files that are marked as configuration files in the RPM 
packages and have changed. If you has installed tarballs etc, you will obviously
have to add any configuration files for those manually. We normally do this
during OS updates so we can quickly look back at configuration changes without
having to go and get the full backup disk.
