I just spent the past couple weeks replacing dvd covers with custom DVD covers and adding movie trailers for all 418 dvd (536 disc) collection.

When I do a backup will that back up my custom covers as well or do I need to save the image folder? Also to keep the movie trailer window do I need to save the trailer.html file as well as my custom layout or will just saving the layout do?

I would hate to have to do all this work again if I ever had to reinstall Windows.
