Again, the system for some reason decides to treat the data like a physical object, and it's little comfort to someone who either loses their Switch to either physical or digital complications. There does exist one way of moving Switch save data: you can move it from one Switch to another, except that it ceases to exist on the original Switch.
That's what you can expect if anything happens to your Switch - something that's much more likely with a portable system. Or, I should say, my second Zelda file, because I lost my Switch on a trip to New York and had to start over, not only with Zelda but on re-unlocking all my hard earned Mario Kart customizations. My The Legend of Zelda: Breath of the Wild file - 120 shrines, a 50 attack Master Sword and just starting The Champions Ballad - is a precious jewel now, to be protected with my life. It's a noteworthy omission in a time when most personal electronics take cloud access for granted, and it's annoying as sin. Once it's on your Switch, that's it: you can't save it to the cloud, and you can't even dump it into a microSD card for safe keeping like you can on 3DS. Cloud Saves: When you save data on the Nintendo Switch, the machine treats it almost like a physical object, immutable and capable of existing in only one place at once.
