do you think you'll ever restore the full backup ? I guess not.
What I suggest is to backup the useful files and data instead, the one you can use and restore (unlike the full dump binary).
I'd dump keys, seeprom and OTP
then vWii key, and all IOS using BlueDumpMod without fake signing (it'll save you from vWii brick !) <-- this one is what most users are needing, they rarely (never? except formatting a CBHC) brick their WiiU mode, but soooo often does on their vWii mode. Really, do that step !
Hint : look at the "I broke my ......" threads and see what users most often does wrong. they are all related to vWii.
most recent post is : I broke/
lost my vWii Miimaker channel !
If you brick your WiiU, too bad. you'll probably never fix it, so full 64GB dump is quite useless.
if you brick your vWii, you can fix it without hardware mod.
Though, the otp and keys could be used for other things (like mounting/extracting your USB HDD content on computer. I guess only very few users would do that, but it's an option)
