Linux Mint

Welcome to the club! Make sure to set up automatic Timeshift snapshots, just in case you break something badly, you'll be glad you have a recent daily or weekly backup instead of a manual one from months ago.

Also, a friendly reminder, Timeshift is not a backup of your data. It snapshots your systems settings, especially critical functions which allows you to restore functionality, but you still should have your actual user data backed up somewhere else.

Another tip: familiarize yourself with Timeshift in the terminal. The GUI works great, but if you break your system badly enough, your desktop environment won't load. (Don't ask me how I know.) In that case, Timeshift is awesome because it will still run fine if you only can access it from the terminal. The commands are easy, and you don't have to memorize. Just type timeshift --help and it will list out all the commands you'll need to know.
