I read that it is possible to set up a network based “Time Capsule” service for use with “Time Machine” in OS X. This requires setting up Apple File Sharing (AFP) with Ubuntu Linux. This was a bit of a pain to set up. Got it working after a couple hours of struggle.

• Set up netatalk to share a folder
• Add the .com.apple.timemachine.supported file
• Create the sparsebundle on your mac and copy it to the NAS

Below are some links and more info

I hope to type up a complete howto when I get time. In the mean time, heres some of the links I used to get it working:

Here is a little trick to prevent the netatalk package from updating in Ubuntu:

echo “netatalk hold” | sudo dpkg –set-selections

Also, during my journey, I came across this “Time Machine”-ish software for Linux. It may be worth checking out for automated Linux backups.
