All you need is one of these adapters, and you can dump the eMMC chip from whatever imaging app you want, Linux on a PC would be my go-to choice.
No i didn't misunderstand - i know that's how it works but doesn't the dump include the whole nand? I.e. complete 1 to 1 copy of your whole NAND. Isn't that the point? Sure they changed this on 3DS though so you could just dump the SYSNAND (2.7G) as a backup though.
Sure ;-) I know how to dump eMMC NAND's. I just want to dump it with the Linux I've got already running on my switch using dd without having to use any other external parts.
Ah, okay. I wasn't sure what your end-game was. I think you'll need a 64GB microSD card as a minimum then, just like the Wii U.
Why are you guys making this so complicated. You have a full operating system on your switch with all sorts functions. Just set up a Samba share on your host PC and dump the Nand over wireless to your UNC path. No need to dump to an SD card and carry it over to the PC like we are troglodytes.

Network dumping is so fucking slow though, no thanks. The Switch is soft-capped at 50 Megabits /sec which crawls for a 32GB dump.
Supposedly kate has a payload that turns the switch into a usb stick & you can just back up the emmc that way.
So if you can't easily back it up now, then soon you will.

if you get linux running, read the nand from /dev/mmcblk1.

The only problem I see with this statement is a soft cap is not possible when the switch is running a completely different operating system apart from the traditional boot loader. It's also been mentioned here the issue is with the eMMC speeds of the flash controller:

This means, you will be getting, most likely, WORSE speeds dumping to an SD card as that is now bottlenecking at the card controller / flash chip.
In other words, network dump is your best bet.

Nope. Not yet. But I can see them coming even from SciresM him self in the future
For Now, you have to create payload that can do it
Damn. I had my fun seeing Linux run on my Switch so I'm going to hold off an anything exploit related until stuff starts coming out. Knowing how powerful the exploit is, I don't want to risk anything until I back up my NAND. (I'm sure running Linux won't somehow corrupt your NAND, but JUST in case)
That is not for NAND recovery. There is no public payload for NAND recovery yet.
Yep, thanks!
@ktemkin Sorry to disturb you, but when is the mass storage payload scheduled for release?
I overlooked the OS doing the softcap, and you're right. I must have been tired.

A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."+2 -

anyways, we need to re-normalize physical media+1
if i didn't want my games to be permanent, then i'd rent them -

Agreed, that why I try to buy all my games on disc, Xbox anyways. Switch games (which I pirate tbh) don't matter much, I stay offline 24/7 anyways.

@BakerMan - you can still "own" digital media, arguably easier and better than physical since you can make copies and backups, as much as you like.
The issue is DRM -
@
cearp:
You can buy drm free games / music / ebooks, and if you keep backups of your data (like documents and family photos etc), then you shouldn't lose the game. but with a disk, your toddler could put it in the toaster and there goes your $60
