Backaroo
Once you’ve downloaded Backaroo, you’ll see it’s actually just 2 simple apps: a ‘Sender’ and a ‘Receiver’. The Sender goes onto machines that will send backups, and the Receiver goes onto the machine that will store them. Senders transfer backups to the Receiver, and the Receiver displays the central status. It’s thousands of times more efficient than Time Machine in many situations. It has more features, it’s more configurable, more secure, and has wide OS compatibility. Backaroo uses rsync at it's core.
