Assuming that you want to pull directory c:\backup on Windows machine to /var/backup on Linux machine:

On Windows machine :

• Install Cwrsync Server

• Start RsyncServer service

• Add a new module to the configuration file rsyncd.conf :

path = /cygdrive/c/backup
read only = true
transfer logging = yes

On Linux machine :

• Use the command below to initiate rsync:

rsync -vrt windows_machine::backup /var/backup

NB! Keep in mind that the recipe above is suitable for operations within a secure network.
