Provides multithreaded folder backup and mirroring. You can set up multiple synchronization tasks from multiple source directories to multiple targets. This only copies files that differ from source to target. The program can even process these jobs in parallel. All file systems are supported, using conventional or Universal Naming Convention file names, allowing access to all local and LAN directories.
