You can Download the last version of cygwin-rsyncd for Windows, or download the 3.0.9.0 version Here if you don't have an internet access
When you download and run cygwin-rsyncd, the cygwin and rsync files are installed in c:\rsyncd. A new windows service called RsyncServer is created and activated (ie: run). The c:\rsyncd directory will have an uninstall executable which will remove the service and installation files.
You will need to edit the c:\rsyncd\rsyncd.conf and c:\rsyncd\rsyncd.secrets files to set your client-specific shares, backup user name and password. You should restart the Windows RsyncServer service to get the new settings or restart your computer.
You can find the rsyncd.conf and the rsyncd.secrets files. They can be used as configuration files, but you can also write your own options in rsyncd.conf. The file rsyncd.secrets contains the master password, you can use it or change it to increase the security. Dont let in all hands this secret file.
Once rsyncd.conf and rsyncd.secrets saved on your windows client and the settings adjusted to the correct values, you need to run a .bat file to adjust the windows firewall (the TCP port 873 need to be opened and the ping incoming request must be allowed). Please use the correct version backuppc-fw-W7.bat or backuppc-fw-xp.bat files. Past the content in a file, name it with a .bat and run it as an Administrator
