Databases - We have all the customers databases from the morning of March 28th, so only changes made that day will be lost. This includes everything on your site except files/attachments/photos. Roster, Calendar, Announcements, Custom Pages, Email Lists, etc.
Files - The files section, attachments, and photos. We are waiting for the drives to be attached to the new device to get access to theses. Same timestamp of the morning of March 28th. These are terabytes (TB) of data, so they can't be moved around easily.
