You don't need to use backups, much less a full reinstall. However, several packages must be reemerged and a couple ones must be uninstalled before you switch to systemd. Obviously, you need to do the opposite to revert back to OpenRC. Which packages must be reemerged and which ones must be uninstalled depends on what do you have installed. It is mostly handled by portage, though, so you don't need to worry about it. If you unpack a stage3 tarball for a new installation, the only thing you need to do to get systemd is to "emerge systemd" and change your init line in your boot loader. Portage will uninstall udev for you, and OpenRC will remain, but it would do nothing. The more things you add to your system, the more packages will be affected by the change, in either direction. Also, systemd requires more kernel configure options enabled than OpenRC. To change back, usually you will only need to unemerge systemd, emerge udev, and perhaps USE=3D"-systemd" emerge -uDNvp @world. Be warned that the best thing to do is to do it from a LiveCD; if you boot with systemd, and uninstalled it, I don't think the shutdown would be clean.
