The punchline to this article... "The USB 2.0 specification states that you can use up to 127 USB devices". None of which are backed up! Don't attach a data drive to the TC USB drive
After hours on the phone I've been told that devices attached to the USB port on a TC are never backed up. Is the community in agreement? If so I am of the belief that Apple is overselling the USB functionality of the TC USB port. There are many articles in the community stating that users are moving iPhoto and iTunes libraries to external drives connected to the TC. Do these users understand they are not getting backed up by TC?
