How are you accessing Jellyfin? Local only, via VPN and/or reverse proxy? Anything else you have changed on the system in general?

Borg an Restic should both be able to do that. I personally use Borg on my Storagebox and have scripts on all my devices that push periodic backups.

True, but it’s still in beta and Pangolin has other useful features like built in geoblocking and authentication.

Arch for Gaming/Desktop, Debian for Server/Proxmox/VPS.

This. I just moved from Nginx Proxy Manager + Headscale/Tailscale to Pangolin and it’s incredibly easy.

Yes, but I also want to run the client in a container and the docs recommend to run the container using network_mode: host. And I suspect this creates a conflict in networks. So I want to have Netbird server, Netbird client and Nginx Proxy Manager all in containers share the same network.
