rsync 4 Windows

В мире юниксовом хорошо известна тулза rsync. Резервные копии, просто копирование, синхронизация и подобные ништяки. А что в MS Windows? А в ней, родимой, есть DeltaCopy

DeltaCopy uses the rsync as-is - meaning the binaries for rsync that are available on Linux/UNIX operating systems are recompiled on Windows using CYGWIN libraries

…

DeltaCopy uses the rsync protocol to transfer files. This protocol listens on TCP/IP port 873 by default.

rsync protocol by itself does not offer a secure channel of communication. However, when bundled with SSH, rsync can be performed securely with encryption.

…

Using DeltaCopy users can backup/restore files from an rsync daemon running on any platform. DeltaCopy server is typically used on Windows that runs rsync daemon in the background. Linux/UNIX comes built-in with rsync binaries and therefore, DeltaCopy is not required.

…

DeltaCopy uses CYGWIN libraries to run rsync on Windows. Windows ACL is not compatible with UNIX Posix permissions. Due to this compatibility users often run into permission issues on the server-end.
