For my small library photos, keepass passwords, etc around 30gb, I use syncthing, which will backup on my pc, on my parents pc (they live in another country), on my sisters pc and on my phone. They also use this triangular mode to backup their stuff. Syncthing is setup to only sync through tailscale or home routers network.
I was in a vacation and I couldn't connect to a remote pc. And since then I set up wireguard in all routers and I also changed syncthing LAN only.

Also why you sync through LAN only?
