Unison is a file-synchronization tool for OSX, Unix, and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.

Unison is ideal for real-time synchronization across multiple platforms, while GS RichCopy 360 Enterprise excels in high-speed data transfer and advanced backup features. Both tools have their strengths, with Unison focusing on synchronization and GS RichCopy 360 on backup and file management.
