What do these do exactly? I was planning to restore my nand in the future to before I used SXOS, but don't have these, only have the 29.1GB rawnand.

As far as the end user is concerned, it's good to have these backed up for the following reasons:
- They're needed if you're restoring a NAND backup from a different system version than the one you're currently on (e.g. downgrading).
- In case you corrupt BOOT0/1 and can't restore them (e.g. AutoRCM)
it's completely normal.
All the 0's in the data just get stripped during the compressing.

Backup BOOT0 and BOOT1 with AutoRCM enabled (boot data corrupted) can lead to any problem in the future in case i need to use my backup to restore my potentially soft bricked Switch?
I was wondering if anyone could advise me, I made two backup's of my NAND (and Boot0/1) however both times when I compressed them they come to nearly 22.7GB and the 7-zip file when compressed is 22GB. anyone suggest how I can compress it down to what everyone else seems to be able to compress it to?
guys, the compressed size of your nand backup depend on what is actually on your switch, so all raw backup will be max size available on your nand (29.1GB), but if you have nothing on it if will just remove all the "empty space" in it, to leave only the really used space, when you compress it
so if your switch is full with stuff, your compressed nand will be big anyway
there is no "magic compressing algorythme"

sorry My post bit unclear, overheating here at the moment, WinRAR is 22.7GB 7-Zip is 22.0GB
This is where I'm totally confused, my NAND is empty, well there's a few files that Mario Odessdy installed but it says that is only few MB in size, other than that everything is on my SD card
To explain this more simply, the archiving app just sees all of those useless '0's in the full NAND backups and skips them and keeps any actual info left. This is why compression is so useful on ROM dumps or even some of your untrimmed XCIs, you don't need to be storing blank space if you can help it.
It's also why the size that people end up with will vary big time based on how much free space was left empty on the NAND for the archiving app to 'skip over'...

If you had previously installed things, there's a good chance the Switch isn't going to set the NAND back to 0's when it's deleted (Waste of a write cycle), it's just going to flag that area as free. You most likely have had up to 22GB in use throughout the NAND in the past.sorry My post bit unclear, overheating here at the moment, WinRAR is 22.7GB 7-Zip is 22.0GB

Ah ok, that might explain it, when I had first got my sd I downloaded my games that must have been what caused the space to be "used", would there be a way to free or "zero-out" on the switch side? I know may seem like waste of a write cycle but the extra space I could save on the backup I could store my sd too

@Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.+1 -

They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".

@SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme -

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."+1 -

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