I have used NoF 10 to build a website including the guestbook component. I have taken a security backup of the entire website via my web host's backup/restore facility, which appears to zip up all files into zip file and downloads it to my PC. However I am not sure if this backup will include the guestbook entries, as I would have imagined these to be saved in some sort of database but I cannot find one. Are they perhaps saved just as text files somewhere? How can I confirm that they have been included in my backup?
