This is explained in the rsync documentation, read the man page for more info. 
You either need to use rsync with a remote shell such as rsh (boo, hiss) or 
ssh (yeah), or you need to use rsyncd and rsyncd.conf. Ultimately you will 
need something to connect to, be it sshd, rsyncd or what ever.

Do you want everything mirrored exactly all the time (real time)? If so, your 
best bet may be to rely on whatever your application can provide. Using 
rsync, the "target" will almost certainly lag behind the "source", 

Could you be more specific with what you are trying to do?
