What Software R U Using for System Backups

Well, heretofore, I was using Redo Backup to backup the Linux Mint 19.2 (Cinnamon) installation on our Samsung Notebook; however, since the installation, Redo Backup has been acting wonky - it keeps running after the timer indicates that it's supposed to be finished. I manually stopped the program and there IS a backup file created, but I'm hesitant to test it because I have a working system right now.

What software are you guys using to back up your Linux Mint install images (and please don't recommend Timeshift - I prefer something more geared to the neophyte). :)

Thanks, guys! ;-)
