Apple Time Machine backups to Ubuntu network drive

Apple's Time Machine is an awesome utility but gets frustrating when you have to use an external drive. An easier was to do these back ups is using a network drive. Fortunately, the netatalk package installed on an Ubuntu server can provide the functionality you want.

I am using Ubuntu 9.10 on my server. As a note, this is actually a MythBuntu server but functionality should be the same on any other Ubuntu 9.10 server/workstation.

First, as of this writing, the netatalk 2.0.5 packages are not available in karmic's repositories so let's add a debian repository by adding the following to /etc/apt/sources.list:
deb sid main

Now let's install the netatalk package:
sudo apt-get install netatalk

Create a directory for time machine backups:
mkdir /home/user/timemachine

Now we need to edit the /etc/netatalk/AppleVolumes.default file and add the following line:
/home/user/timemachine timemachine options:tm

And restart netatalk:
sudo /etc/init.d/netatalk restart

Now on your mac, open finder, select the Go menu and "Connect to Server". Fill in your server's ip address prefixed by afp:// (for example, afp:// and you should be prompted for a volume to mount. Select "timemachine", of course. Once that volume is mounted, go to time machine preferences and select that disk and you're all set. If you don't see your network drive as an option then open up terminal and issue the following command:
defaults write TMShowUnsupportedNetworkVolumes 1

As a note, you may want to now go and remove the extra line from your /etc/apt/sources.list file so that future apt-get commands don't rely on debian's repository and not it's own
