3-2-1 rule with restic. Check it out.
I self-host FreshRSS as a container with podman behind Traefik on a raspberry pi 5 and use the web interface on desktop and FeedMe on android. Pretty happy with the setup.
Endeavouros on Laptop and main PC. Loving it.
Serial Experiments Lain, Perfect Blue and Ghost in the Shell (Original Movie)
Came here to say restic! It’s really good.
I like restic too.
TL:DR Buy a pre-installed laptop of your liking, be it windows, Mac or even Linux-based.
I guess non tech users would go into a store and buy a laptop with Windows or MacOS pre-installed. You boot it up, go through some questions and boom you are ready to go.
It appears that you are expecting that same experience with a DIY installation of an unsupported OS on some random hardware. You cannot expect it to be so smooth.
So what I really suggest is that you get a laptop that is designed with Linux in mind from scratch.
Go to tuxedocomputers.com or system76.com and just buy a preconfigured Linux based Laptop. It will work out of the box. Problems solved. Easy peasy.
