Our church presently has a peer-to-peer network of 12 PC's, all running XP (mixture of Home and PRO), and 3 networked printers. One of the PC's (XP PRO) is used as a "server" and contains a database accessed by the other workstations. Also, this PC is a collection point for backups of "My Documents" folders from each of the other PC's. Each PC runs an application (GoodSync) each time the user logs off, which propagates changes from the workstaion to the "server". Our present scheme of maintaining confidentially on the backup files/folders on the "server" is to set up a login on the server for each user with the same loginID and Password as on their individual workstations. Sharing is enabled with only the owner having access to the backup files on the server. Each evening the "server" moves file/folder changes to an offsite backup facility (Mozy). We replace one or two PC's each year. This year we would like to replace the "server" PC with a Windows 7 machine. Since this will be our first experience with Windows 7, we would like to know what to expect. Security, confidentially and stability are very important. What are the issues we will face in order to make this system work reliably? I would appreciate recommendations and comments.
