@Zakary_1: I think the clue is in Kovid's post:

That file contains lines like:
Code:
"bookmarks_E:\\Library\\Testing\\Aaa Zzz\\EPUB FontTest (447)\\EPUB FontTest - Aaa Zzz.epub": "calibre_current_page_bookmark*|!|?|*0*|!|?|*/2@0:0\n",
If you restore the library to a new location, the file path for the book will be different. When you open the book in the new library, it will not be able to find records to match the new path.
There is an option to store the bookmarks inside the files. That will mean they move with the books as you move the file. It will mean the files actually get changed. And there is a possibility that this could cause problems with some reader app. But, if the bookmarks are important to you, this might be the best choice.
