Unison File Synchronizer is a tool that enables two copies of files to be kept on different computers through synchronization.
One of its key benefits is its ability to run on both Windows and many flavors of Unix, including Solaris, Linux, OS X, etc. This feature means that Unison works across platforms, allowing you to synchronize a Windows laptop with a Unix server, for example. Unlike simple mirroring or backup utilities, Unison can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are propagated automatically, while conflicting updates are detected and displayed.
Unlike a distributed filesystem, Unison is a user-level program that requires no modification to the kernel or superuser privileges on either host. It works seamlessly between any pair of machines connected to the internet, communicating over either a direct socket link or tunneling over an encrypted SSH connection. Additionally, Unison is careful with network bandwidth and runs well over slow links such as PPP connections. Transfers of small updates to large files are optimized using a compression protocol similar to rsync.
Unison is resilient to failure and is careful to leave the replicas and its own private structures in a sensible state at all times, even in case of abnormal termination or communication failures. It's transparent, reliable, and boasts a clear and precise specification that users can rely on. If you need a file-synchronization tool that works across platforms while remaining fast, reliable, and resilient to failure, then Unison File Synchronizer should be your go-to tool.
