Unison
Overview:
Unison is a file-synchronization tool for 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 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). However, there are several points where
it differs: Unison runs on both Windows and many flavors of Unix
(Solaris, Linux, OS X, etc.) systems. Moreover, 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. Conflicting updates are detected and displayed. 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. 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. It 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. It 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. Unison has a clear and precise specification. Unison is free;
full source code is available under the GNU Public License.
