Abstract: Back-Up (B/U) data is made immediately available to users on a networked client-server system by standard file sharing protocol methods using the user accessible Back-Up and Restore (B/U/R) process of the present invention. Implementations of the invention first extract file data and file meta-data from user files during a B/U by a B/U application. The B/U/R invention process uses the extracted file data and file meta-data to build a B/U file structure containing the backed up user files on a B/U storage device. The B/U file structure is constructed so that it is responsive to File Sharing Protocols common to the clients (users) of the system. Thus, once a user's file is backed up by the B/U/R process of this invention, it is immediately accessible to the user from the B/U storage device in the event of client's data loss, corruption or a server system crash.
