Teacher here. No professional affiliation with PCs, Linux or self-hosting. Started out with a Synology NAS and got my first experiences with Linux, CLI, Docker, etc. Switched to Unraid last fall and I self-host quite a lot of services now. 100% self-taught.

I‘ve been using a Hetzner Storage Box with Kopia via SFTP and was able to completely saturate my 500 Mbit/s upload.
