Hacking How often do you backup you nand?

Every update when a fuse gets blown - you should make a back so you can restore.
Basically every time you add a game/install an nsp - data gets written to the nand and changes bytes 00 to something else. You can look at a clean nand dump in a hex editor and see what bytes are changed. Then compare it to an updated nand image where you installed some stuff.
In a dumped sx os nand - you can make a clean nand using a hex editor - then test your clean nand by putting it in the emunand folder and testing it works.
I do it like this:
Dump an updated nand (6.1.0 for now).
Don't touch boot1/boot2
Edit:
full.00.bin - jump to address 53362000 - edit everything under this address - make bytes 00
full.01.bin - full.06.bin - change all bytes to 00
full.07.bin - from - address 00 to 47cdfdff - change all bytes to 00 (don't touch anything under 47cdfdff).
Now copy all modded files to sxos - emunand folder and boot into emunand.
Open ChoiDujourNX and update emunand to 6.1.0 (ex-fat) - and in the options uncheck prevent fuse burning (auto rcm), check System initialize (full factory reset). Then start installation.
Now shutdown the switch and remove the sd card - make a backup of emunand folder - this is now your clean nand you can restore from.
Now test the modded nand files in by booting into emunand - it the switch boots properly and functions properly - this would work as a new clean nand backup.

I have two extra 4tb drives that have all of my consoles install able files and hdds. It's a boon to have especially if you're inexperienced
Be aware of another thing: Your Nand has your saves. So if you restore a Nand from along time ago all of your saves made since that time are gone. Of course, you could just backup your saves seperately.
All good information, thanks guys.
For backing up my nand, should I stick with hekate ctcaer or use sx os? Or does it not matter?

I done it the first time Homebrew came out when I was on 4.1.0, I burned a fuse updating to 5.1.0 but still keep that backup as it may potentionally be useful one day (though unlikely) as from what I've heard if you're using RCM and skipping fuse checks it's still works (unless I've been misinformed) it just doesn't work on stock.
So on 5.1.0 I done the exact same again, incase I ever needed to wipe everything dodgy done on the console and go 99.999% clean.
I managed to dodge the fake NSPs making the round over the months but before Smash comes out... I'm making another backup as there is sure to be plenty of fake ones making the rounds. I've gotten lucky far too much so far, you should make a backup before/after updating without burning fuses and also if you have a lot of changes, do it before installing a newly released well desired game NSP as well, you don't want to lose everything and worst case scenario, end up with a brick.

Twice, one after unboxing, and one after (fuseless) updating to v5.1.0. I will make another backup before trying some of the dangerous stuff (i.e downgrading)

You should only need to have two back ups.
One of a clean out of the box nand. This one you keep however long you have your console.
Second is a copy of the nand you have your current official firmware on. This one you will throw away after you update you console and create a new nand backup if you choose to update your firmware.
Aside from that you do not need to make daily or weekly unless you are severely tinkering with you switch.
But you might want to use checkpoint to backup you save data daily?

I was wondering, I still have my old 2.3 backup but since I have updated to 6.1 and so burned the fuses it's useless right? I should only have the latest backup everytime I update the console?

Or, I also heard that if you use flash memory, it can act as more "RAM" at least windows tell me when I stick a flash drive into it. -
