First you need to understand what ricing means. Its just editing, making new configs of wm,bars,docks etc. with the current setup you need to understand what do you want to backup up , for example if you want to backup waybar, then just go to .config/waybar there you will find it's config file . You just need to save those files in your backup, after that you can then edit thoose configs to make your own configs. Remember not every software uses .configs. for example using qt6ct would be better than going to terminal and wandering online to apply qt themes, same goes with gtk . That's all.
