emerge --sync only updates the portage tree, that is, the set of
available packages. it has no effect on what is actually installed on
your system. /etc/conf.d, on the other hand, contains configuration files
used my various Gentoo startup scripts. the two are not related.

If you want to test packages on one system before emerging them on the
other, just do so. emerge them on the test system, when you are happy,
emerge them on the stable system. I run ~arch on my laptop and my desktop
but tend to update packages on my laptop first, on the basis that I'd
rather mess that up than my desktop. Certainly with important packages
like baselayout, I emerge them on the laptop and reboot before trying
them on the desktop.

If you want to backup the portage tree, /usr/portage less distdir and
packages is what you need; but, as already mentioned, you can simply roll
back a day by grabbing yesterday's snapshot fro one of the mirrors.
