I've got a SD card that has only my NAND backup on it from about 6-8 months ago. I did this with BootMii. I'm still on 4.2U atm and just wondered if this is still the best viable option for the foreseeable future in-case I screw something up... which I know I won't do.
Also another question, how often do you 'update' this NAND backup or is once enough?
