I do this for backing up our various servers. I have one machine that is running Rsync as a daemon 
and the linux box's PUSH there updates to it. I then use autofs to mount shares on various windows 
machine and rsync these to the server, sort of pulling. Seems to work fine.

To do the passwordless bit have a look at this page as a start

http://www.hantslug.org.uk/cgi-bin/wiki.pl?LinuxHints/SSHwithoutPasswords

But this page was what I used

Basically this is what you have to do

generate sshkeys on the machine you wish to rsync FROM

       ssh-keygen -t dsa -b 4096

       (just hit enter for all the questions)

       chmod 0644 ~/.ssh/id_dsa.pub

       copy ~/.ssh/id_dsa.pub to rsync server into /root/.ssh

       cat id_dsa.pub >> authorized_keys
