Backup and restore

I have a WIMP Server (Windows 2003, IIS 6, PHP 5.1.4, MySQL 5.0.22) and have been trying to migrate some data from my previous years install to the current install. I have a course that has a variety of categories and questions in them; however, they do not seem to be part of the backup. These questions are not used in any quiz as the teacher was just playing with them to get started with Moodle; however, it seems that they are not getting backed up. I did not see a questions check box to indicate to backup the questions. With the separation of questions from the quiz module it seems like something might be missing here. Any suggestions or insights would be appreciated as to what might be causing these questions not to be backed up. Thanks - Anthony
