The backup button is for the entire mysql database file, all of your content (Anything added into the CMS) - with your site though Bob, we have a TON of extra stuff that isnt in the CMS (Things in the custom IDX etc) so I think with a site as complex and advanced as yours, its best to get Aaron to manually backup all data. - I will be in new york at the SES all next week, but if you send him an email he will be in normal office hours.
