Remote backup using a mac mini
Hello...I have a 2.6 Ghz Mac Mini that I would like to use as a remote, i.e. over the internet, backup for a MacBook Pro using Carbon Copy Cloner. Both systems are running Yosemite. I can see the mini when I am connected via my local network, but do not seem to be able to connect to it when I try to access via the internet. I thought that it might have to do with port forwarding, and have tried all sorts of combinations, all to no avail, so I am now at the stage whereby I feel that I have just missed something obvious. Can anybody please advise if there is a simple step by step guide somewhere that will help me achieve my objective? Many thanks.
