I was actually talking to my dad the other day. He asked me if there is a way for him to replicate his hard drive to me without touching cloud providers. The contents are family photos & videos, plus paperwork. I couldn't find a simple solution.

Syncthing will do a 1 to 1 connection if possible, else it will use a relay server. Traffic is encrypted. Open source. After the initial setup of marrying the devices together, it's just a matter of starting the application. Pretty much what you want?

Doesn't it still need a public relay server? I understand that's nitpicking, since even with tailscale, I need someone in the cloud to handle the IPs.

There are community-contributed relay servers that you can use. Check out the syncthing website, they explain how all of this works. It's a very good piece of software.
