Question Did I do the backup correctly?

    I follows this guide (https://guide.sdsetup.com/#/safetyprecautions) and backed up my Nand according to it. After that I installed some nsp Files. Now I came across this guide (https://gbatemp.net/threads/backup-...-your-biskeys-tseckeys-keys-txt-guide.513386/) and it backups way more files than the guide I used. Did I mess up now or do I have the most important files to restore it once I want to get back to a clean Switch? Right now im doing the second tutorial (and skipping the files I already backed).

    If your plan is to restore your Switch to a pre-hacking state, you technically only need the rawnand otherwise known as raw eMMC GPP (if you want to be real cheap, you can backup eMMC SYS). However if you are changing firmware when restoring the NAND (in case the NAND dump doesn't match the firmware you are currently running), then you will also need to restore a boot0/boot1 that matches the firmware of the NAND dump you are restoring since those are also firmware-specific. Outside of AutoRCM (and SX OS EmuNAND), boot0/boot1 are unaffected by any hacking so you can and should back those up.

    All of the keys however that guide has you backup are completely optional and only needed for very specific circumstances.

    Following happened:

    Did a backup before I did anything on my switch, saved it on external hard drive. Hard drive isn't working anymore.
    Did a backup again after two nsp files installed.
    Now I found on my bin a rawnand.bin and it could be the version before I installed anything onto it. Is there a way to check if it is the clean nand?

    Outside of restoring it then checking if you get banned, not really. Also if the firmware of your rawnand.bin differs from your current firmware, you will need to restore a dump of boot0/boot1 that matches the firmware of the rawnand.bin otherwise, the console will be soft-bricked.
