Syncthing! I have selected folders (pictures, video, notes) that sync to a NAS, which I then backup elsewhere. My current phone also has an app that is one button backup (for apps + system settings). I press the button and it creates a single timestamped file, which also is placed in a folder that syncthing watches. It's truly effortless.
