Backup function for hidden Partition EmuNAND

[Big_BO$$]

Dear Sirs and Madames,

is it possible to add a function to copy EmuNAND from the hidden partition? To create a backup. And then reinstall this backup later on a hidden partition.

Excuse my bad english, google translate helped me: D

best wishes

There is currently no way to do this on the switch, and to do this is redundant, since the partition is already on the SD card. Makes much more sense to plug it into a linux computer and use a tool like DD or Partclone or any other partition cloneing app, and make the backup that way.

I guess it would be nice to be able to back it up to your pc or something in case your sd card ever fails

Use dd for windows http://www.chrysocome.net/dd (or dd in linux)

For windows, plug SD with an USB adapter
dd --list ans search your SD
...
\\?\Device\Harddisk3\Partition0 -> is my SD Card Partition0 (Hidden EmuNand)
...
dd if=\\?\Device\Harddisk3\Partition0 of=first1024.bin bs=1024 count=1
dd if=\\?\Device\Harddisk3\Partition0 of=boot0.bin bs=1024 skip=1 count=4096
dd if=\\?\Device\Harddisk3\Partition0 of=boot1.bin bs=1024 skip=4097 count=4096
dd if=\\?\Device\Harddisk3\Partition0 of=rawnand.bin bs=1024 skip=8193 count=30535680 --progress

For restore ou for a new SD KEY

dd if=first1024.bin of=\\?\Device\Harddisk3\Partition0 bs=1024 conv=notrunc
dd if=boot0.bin of=\\?\Device\Harddisk3\Partition0 bs=1024 seek=1 conv=notrunc
dd if=boot1.bin of=\\?\Device\Harddisk3\Partition0 bs=1024 skip=4097 conv=notrunc
dd if=rawnand.bin of=\\?\Device\Harddisk3\Partition0 bs=1024 skip=8193 conv=notrunc --progress

just use checkpoint and backup save game files and copy to PC. at most 100mb vs backing up whole emunand 32gb.

NSPs can just reinstall no problems.
