    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.

      sync is not backup

      Also why you sync through LAN only?

        It's tailscale or local LAN. syncthing allows you to specify multiple addresses for the same peer

        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.

      So you delete a file by mistake and it replicates within seconds? Not exactly a backup. And a malware will do that to all of your files.

        Yes, but I setup syncthing's file versioning to 25, in case of keepass, for example. Also, I set it up that only my PC can send, all other PCs, smartphones, can only receive. Sure, there are still many ways to attack this system, but I still prefer it.

          As long as you have different credentials on all of your machines. I have witnessed first hand that once a malware infects a machine, any machine with shared credentials in the vicinity is infected within seconds.
