![]() Once Unison has scanned the directories,you can specify the way it should handle conflicts with the options available under the Actions menu. Pressing the Go button performs the sync.Īlthough the basic operation of Unison is pretty straightforward, it offers a few advanced features, including a powerful and flexible conflict-resolution mechanism that provides a comprehensive set of options. Unison then checks both directories and displays all the files to be synchronized. Simply specify the paths to the directories you want to keep in sync and you are done.Įnter Second Directory.As you can see, Unison supports synchronization via SSH, which is a handy feature for syncing remote machines. When you run it in GUI mode for the first time, you’ll be prompted to create a new synchronization profile. If you want to open goto Applications->Internet->Unison Unison is free full source code is available under the GNU Public License. Unison has a clear and precise specification. It is careful to leave the replicas and its own private structures in a sensible state at all times,Įven in case of abnormal termination or communication failures. Transfers of small updates to large files are optimized using a compression protocol similar to rsync. It is careful with network bandwidth, and runs well over slow links such as PPP connections. Unison works between any pair of machines connected to the internet, communicating over either a direct socket link or tunneling over an encrypted ssh connection. Unlike a distributed filesystem, Unison is a user-level program: there is no need to modify the kernel or to have superuser privileges on either host. Conflicting updates are detected and displayed. Updates that do not conflict are propagated automatically. Unlike simple mirroring or backup utilities, Unison can deal with updates to both replicas of a distributed directory structure. ![]() Moreover, Unison works across platforms,allowing you to synchronize a Windows laptop with a Unix server, for example. Unison runs on both Windows and many flavors of Unix (Solaris, Linux, OS X, etc.) systems. Unison shares a number of features with tools such as configuration management packages (CVS, PRCS, Subversion, BitKeeper, etc.),distributed filesystems (Coda, etc.), uni-directional mirroring utilities (rsync, etc.), and other synchronizers (Intellisync,Reconcile, etc). 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 a file-synchronization tool for Unix and Windows. ![]()
