time machine back up to remote macs over lan and internet
BACK UP OFTEN!!!!
Now that I have my mac mini set up as my home server I also wanted to backup its system drive to preserve all the configuration. I have an Airport extreme basestation that has a 500GB hard drive hooked up to it. I have used it to back up my mac book pro over the air and it worked just fine. When I tried to select it as the backup drive for my mac mini the time machine preference pane would crash every time. So I played arround with it and it appears that time machine is now able to backup to any afp:// file server. It is important that you mount it using the following instructions and not just click on it in the finder. It appears that apple does something differently when using the shares in finder.
Setting up time machine with a remote destination
This is done by pressing command + K in finder and using OS X built in ability to connect to different file servers
You might get prompted for user name and password. Once connected the afp source shows up in your finder.
In my case that is the airport extreme base station called chrillo.Airport with the hard drive. This could also be another mac. Now head over to your time machine preferences and the click the change drive button.
As you can see it shows up with its Ip address. In my case I used the internal Lan IP
