So far I've used three different genealogy programs. They all had one thing in common: the backup files were all stored within the Program Files directory of the computer. If you do that, if a PC tech tries to restore your PC and has to reimage it, you will lose your work as I did. The PC tech only saved My Documents. I highly recommend you create a file under My Documents to save the backup file. I also suggest that you regularly save your email address book and My Favorites under My Documents, just in case.
