Abstract (en)

[origin: WO9849626A1] A mirroring system (14) for a network (9) operates to backup work product from workstations (13, 15, 17) on the network to one or more file servers (19), and also performs updates of changes in master copies of work environment to workstations (13, 15, 17) from the one or more file servers (19). In some embodiments the mirroring system (14) checks for network traffic level, and only initiates data transmission if traffic is at or below a preset level. As backups and updates occur, a status list (29) is maintained to track the update and backup revision levels at each workstations (13, 15, 17) on the network. In some embodiments, workstations (13, 15, 17) failing to backup or update are listed and reported.
