Using one server as the master and two as slaves, you can either have a push approach or a pull approach. In the push approach, you have a script that forces a synchronization of the local contents with the contents on each of the two slaves. In the pull approach, you have a script on each of the two slaves that at regular intervals synchronizes with the master. The push approach makes more sense in that you get instant propagation, but requires that a script be run after the upload has been committed. For both, I highly recommend the use of rsync or an rsync-enabled tool. rsync with key-based SSH is a great way to automate secure synchronization between a master and multiple slaves. --> Jijo -- Federico Vicente C.
