It should be noted that journaling on the HFS volume should be off or the Raspberry pi will not be able to write to it. When I set this up @ home, I formatted the disk in OS X first with journaling off, and then connected it to the RSBPi. Very effective, cheap backup solution. You can also then use crashplan to upload your backups to the cloud as the RSBPi receives them.
