Cool. In the process now. So Im not supposed to backup system data ever with TB? What exactly is system data? Like Wifi passwords? Bluetooth pairings?
It's not that you're not supposed to do it, there are just lots of issues tied to restoring it so it is recommended you do not do it. And stuff like that would fall under it but it includes any settings that are tied to apks located in your system partition (apps you download are in data).
