CwRsync是基于cygwin平台的rsync软件包，支持windows对windows、windows对Linux、Linux对windows高效文件同步。由于CwRsync已经集成了cygwin类库，因此安装的时候可以省去cygwin包。Cwrsync还集成了OpenSSH for windows，可以实现Linux 下Rsync一模一样的操作
cwRsync Free Edition contains a barebone distribution of Rsync for Windows. Unzip archive contents to a directory, update the supplied batch file cwrsync.cmd. That's all you need to be able to initiate rsync from your computer.
