Screen Saver files not copied over?
 

Before I left my vacation home, I changed my screen saver pictures and screen saver instructions. I then did a full erase and backup. When I got to my main home, I booted from the external and did a smart update to the home HD, but the screen saver data did not change to the new settings.

I believe the screen saver preferences are stored "by host", and so your other Mac would have its own settings.
