I have raid 5 to protect against hdd failure and I run syncthing and duplicati on immich and other folders for on premise and remote backups.
What I’m curious about is how people make stuff like Immich and nextcloud available to other people outside their network? When I need to access something remotely I vpn in. I know I don’t have the knowledge to have my server connected to the open internet in a secure manner. I don’t think someone like family members would ever want to bother with anything other than a link and a login page so only me and my partner use these services.






Not trying to tell you to parent better, shit’s hard, but I see two possible things that might help.
First, any device he uses should be filtered from the open internet on router level with a white list of approved things he can access.
And second, you really need to talk with him about it. Why it’s a bad idea to text numbers of the floor, how cards are gambling and how specifically gabling will ruin his life and about addiction and how almost everything on the internet is designed to create it and abuse it. These would be long and not just once conversations with examples and reiterations because the subjects are complex and he will need a long time to process and absorb all that.
Good luck!
