So, setting up an entire server might be overkill for the amount of data I truly want to never lose (passwords, some pictures, some important documents, maybe some music if there is space left) , but asking a relative i see every once in a while to just keep a drive or even a USB stick in a desk somewhere is probably the easiest and reliable option.

Thanks for the suggestion !

okay, but why did they used a guy beatboxing to illustrate their statement ?

Good point, I did not check if my router has already some built-in system that could let me connect to my home network with trusted devices from outside

Tailscale is very tempting, on one hand it should provide a pretty good layer of security without too much thinking and it is “free”, and on another hand, it’s a business solution, so it is probably not really free…

Thanks for the answer anyway confirming that Tailscale is pretty easy to setup !

Okay, so that’s pretty much the setup I had in mind. Good to know there is not much need for an extra step for security, thanks for the answer !

Well, I guess that would still be vulnerable to DDOS attacks, but that would just prevent me from accessing my cinnamon apple-pie recipe from my self hosted recipe manager for some time. A bit mean, but not catastrophic.

I wondered if there would be some other attacks that could compromise my machine with only a wireguard setup, but that’s a good sign if there is nothing obvious.
