Multiple save games at same world

I lost a world at day 30 because a freeze glitch. The game need a another method of save. You need to create multiple slots to save the game, so that if a file break happens, we can create multiple copies of the same world, just like many other open world games do. Please add this to the game as this is very important. I’ll show you a screenshot of an example of a game that performs the multiple save method.
Sorry if I wrote something wrong, because I’m Brazilian and I don’t speak English as a native language.

The reason you can’t (on console anyway) is to prevent save spamming, otherwise a bunch of the achievements would be redundant
