Hacking Backup saves from SysNand to EmuNand without getting dirty the SysNand

[Nic2609]

So as the title says, i have a bought game that i play on my stock switch, and i wanted to backup those saves on my EmuNand.
I think the only way to do it is booting the CFW on SysNand, doing a backup with jksv of the game and then paste it on the EmuNand right?
But i heard that if you boot the CFW on SysNand instead of EmuNand you will dirty the SysNand leading to a ban in the future if you go online (i think).
Is there a safe way to backup those saves? and will it get dirty?

You really only have to worry about unofficial installed titles. If you just load up the homebrew menu in applet mode and use a save manager like Checkpoint you should be fine.

ok thanks, but what about "dirtying" the SysNand?

Just booting a save manager in applet mode isn't going to do anything. Using title installers and shit is what gets you banned real quick. If you want to be extra safe do it in Airplane mode.

ok. Whats applet mode? why are you mentioning that?

Just open the album icon to open the homebrew launcher. This is known as applet mode. Applet mode only has partial RAM access. Some homebrew requires full ram access and doing that requires booting the homebrew launcher through an installed title on the system by holding R while booting. Something as simple as a save manager can just use applet mode.

It should be file, just make sure there is no prodinfo blanking enabled for the SysNand.
Then just start any application while holding r to start the homebrew launcher in application mode, or use applet mode via album.

I use syscfw only for stuff like sysclk and sysdvr for many years now (no idea when I last bootet stock), without any ban.
The main atmosphere devs even expect you to go online with cfw, and develop atmosphere so that it's mostly safe for that.

Otherwise, if you’re afraid to dirty your SysNand like I was with the method above, in order to make sure to keep my sysNand always clean
you can use the NAND dump method.. it will backup saves and all the other in your Nand.. but i know it‘s really long to do

Or can use the method i used to backup my save of Pokémon Violet to avoid the recent Rick of data corruption after the recent update.
I used the TegraExplorer payload, navigates in the SAVE dir, in the option of the current folder I selected the copy to clipboard option. go back to the SD root (or an already created folder) and then pasted the clipboard
whit that done, you have a secure backup of your save that can be restored in the same reverse way

Just keep in mind, this save are only work whit your console, if you need the files inside the folder (for example to modify that) you need to extract them using your console’s key

You could back up your first emunand save data, then delete that one, create a second emunand, and then extract the save data from there and then just reinstall your missing games and restore your first emunand save data.

i think i will just backup the saves from the SysNand, as much as i hope that i will not get banned in the future...

Wow, NXNandManager's cool! Really more userfriendly than my way of using memloader & HacDiskMount!
