I think this is the play. I’ll likely just get an enclosure for the two 4TB drives I have and can always buy an external drive in the future and get them to plug it in.
I don’t have any experience in setting up wire guard so I’ll have to look into that. I was thinking to use syncthing since that skips the need for that, but I think someone in the thread mentioned that may not be ideal in case of file corruption.
Do you just have raspbian on the pi?
