Backing up Air over network to iMacs external HD.

[Qwerty11]

So I think this is the solution I want to go with. I already have my iMac Time Machined to a USB external HD. How do I set my Air to backup to this drive as well? I can view my iMacs HD over the network, but haven't figured out how to access the external drive yet.

I have this exact setup. Turn on file sharing and set it up and you should be able to see the time machine drive when you go to "select disk" on the Air.

It's been a long time since I set that up, of course...
