How do i back up my FM24 Saves?

Just wanted to know if it is possible to back up my FM24 Games, i recently had to get my new laptop fixed but lost all of my FM24 saves when i got it back. When i try to save it to cloud, it says files only up to 400MB, please could you tell me if this is enough, because i thought FM saves are bigger than this?  Thanks Jimmy

Apparently they are decreasing the size of the file able to be saved to cloud before the end of the year from 400Mb to 200MB if im correct. I have a lot of Leagues and Nations loaded so file is gonna be quite big. I'm quite new to FM,  can i pay money to increase the cloud storage or would you guys recommend buying a USB stick and if so how many GB's storage would i need for a few saves?  Thanks
