Hacking Question eMMC user backup fails

[Bl4ckeagle]

Hello Community

I hope I'm on the right sub forum.

Since about two days I'm trying to get the full nand backup(eMMC RAW GPP) but the verification failes of the backup(the thing with the green bar)
So i tried the other 3 options,[boot,sys,user] everything but the user works without a problem.
My question is: do i need the user "partition" or is it just good to have & is there are read up to understand the different "partition"?
Thanks all of you


I'm using the 3.0 payload, alltough I just saw that the 3.1 is released and i will try it in 5 min.
Switch is on 3.1
SD card is a 128GB from Sasmsung Evo, U1 XC 1.

Update:
As @CrAzYLiFe said, it seems to be a bug in 3.0, alltough it took 2,3 hours it worked

Think it was a bug with 3.0, 3.1 should work

I've found the SD card drivers in the homebrew community to be a bit flaky.
I typically had to run the full eMMC backup 4-5 times before it would verify.

Similar problems in the early to medium days of 3ds stuff too.
