Backaroo is comprised of two applications: the 'Sender' and the 'Receiver'. Install the Receiver.app onto the machine which will store your backups. Install the Sender.app onto the machines that will send backups to your Receiver. The general idea is that you deploy one Receiver and lots of Senders, although you can stick both on one machine if you like (handy for testing). The Receiver application gives you a centralised view of the state of your backups.
