How does Windows SBS 2003 R2 back up my user’s information?
By default, Windows SBS 2003 R2 creates a Group Policy that is applied to workstations that join the domain. This policy redirects the users’ “My Documents” folders to the server running Windows SBS 2003 R2 in the \\servername\Users\%username% folder. These folders are part of the automatic backup process on your server. Most Windows-compatible applications store information in the “My Documents” folder. If you have applications that store information elsewhere, instruct your users to save the information into the “My Documents” folder; this will ensure that the information is backed up on a regular basis.
