From the startup menu there is an option to backup to an SD card. However there isn't a SD card slot on the device. I could almost live with having to take the cover off but it's a royal pain to remove.
Even with the cover off you can't insert a SD card unless you remove the circuit board from the case.
I'm going to see if I can file a slot but that won't really help in this case.
Has anyone figured out if you can boot from USB?
