MirrorMaster is probably the best and most powerful replication, backup, mirroring software for the Windows NT, 2000, XP and 2003 platforms. Allowing for multiple projects, users and levels of replications, it includes 448bit encryption and 60%+ compression for all communications. MirrorMaster may also be setup for a multiple level replication of projects, thus distributing the project (root directory) to multiple user using multiple flows (sub directories) per user.
