Many MirrorClients work with a MirrorMaster or multiple MirrorMasters to do backup, replication, mirroring, project management or document management type operations on files and directories. MirrorMaster is probably the best and most powerful replication, backup, mirroring software for the Windows NT and 2000 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. It has been tested using multiple machines mixed with MirrorMaster and MirrorClient programs or services replicating a project containing data (4Gb) 900 folders and 2500 files.
