Thanks for your help.
Ok I am familiar with backing up databases and think I understand now.
So in the event of a server catastrophe, I can upload my base site again from dreamweaver then add the recovered database... how? My exp has been with Joomla! where I reinstall the entire site with an established database and the pages are restored. But how are the pages to a SiteAssist site restored in such a scenario?
Are the new pages added to the site map?
If I update the structure of the site with new or revised menu additions, will this effect the pages added to the CMS/blog portion?
