Have you tried looking at the manpage of the rsync command? Go to the shell of cygwin or ssh to DH, type "man rsync" - there is really good help there. Alternatively, you could google for the same, for most commands it's somewhere online as well.
When I rsync my files I use "rsync -rvlp --progress source user@server:/dir/on/server" . Sometimes I add --address=192.168.x.x if I want to bind to a specific address, because my home computer has multiple network cards on different connections.
Also, add -z if you want to compress the files on-the-fly first to save bandwidth. And finally, if you want to test what's going to be transfered without it actually doing it, add -n.
Hope it helps.
EDIT: Forgot to say, you don't need to configure anything, just run the command from your home computer and watch the files go!
