I don't remember if all the instructions worked precisely without a few tweaks, as the Raspberry Pi software has changed a bit since this was written. But at the very least it's worth just perusing the article to see if this is something you'd like to tackle. I have a Raspberry Pi 4 with a (Western Digital, yeah I know) USB3 hard drive, that is a file server for my family's home network. I have not set up automatic backups, but do it manually by SSH'ing into the RPi periodically. The Pi 4 doesn't seem to like powering two drives at once, so I plug the drives into a powered USB3 hub. There may be better ways of doing this, but of course mental inertia has set in, since it works and has been trouble free.
