I have the same system with 2 web servers and i use rsync over ssh. I
like it because you can backup the modification into a specific dir.

An example that i use :

/usr/local/bin/rsync --delete-after --backup
--backup-dir=/change/`date +%Y-%m-%d_%Hh%Mm` -av
/var/web/www/production/ rsyncman at geronimo:/www/ > /tmp/result
