I’ll have a look into NFS, that might be the way to do it in the short term

I struggle to understand the material on btrfs but I’ll give it another go at some point, thanks for the rec :)

Duplicacy looks really cool! Thanks for the rec. Will have to look into getting a NAS at this point I think!

Thank you! I think restic is the way to go it seems, the docker config seems reasonable. Now to find another hard drive to mount and point it to. Hetzner is very reasonably priced too!

I went through the same thought process as you a while ago, also with CasaOS. I ended up using the *arr suite, Jellyseer and then this container via Portainer https://haugene.github.io/docker-transmission-openvpn/. All the instructions are on there for whichever provider you go with, and all it took was making sure the env variables and permissions were in the right place.
