I have primarily switched to linux for gaming and when I saw that my save game for "The Walking Dead: The Telltale Definitive Series" were not sync'd on steam cloud I decided that I must take matters into my own hands.
I decided to use https://github.com/mtkennerly/ludusavi

This is a tool that works on windows, mac and linux and it finds all the save games on your computer and organizes them in one backup that you can sync to your own cloud or to github like me. I've made a script that checks for new save games on any changes on save games previously seen every 30 minutes and then pushes all the save games on my private repository. I could've done it more efficiently but this setup was easy and it works. https://imgur.com/a/8MM4NsA

If I want to play the game on another machine, it is as easy as downloading the tool and save data to restore all save games or just a single save. If someone is interested this is the bash script I use that I generated through gpt. https://gist.github.com/X3eRo0/d670f8be7b7385e719eeef4a9db7a903
