Toasted_BreakfastWhere do I even start?
It doesn’t get as easier as this (for photo storage backup):
docs.immich.app/overview/quick-start/
It has step by step guide, using very simple commands you can just copy and paste for the most part.
Since you are using linux, and you are in the fediverse I do assume you can move your way around setting up Immich with that guide.
How his looks like exactly what I needed! Thanks. Is this “self hosting”?
Think of self-hosting as - instead of depending on cloud services from other entities (google/apple/whoever), you host those services yourself by running them on your own pc or maybe your secondary pc running 24/7 (usually locally, in your own home).
Some common services might be automatic photo backup and storage (like immich), or running an adblocker for your home network, or streaming movie/music from your hard drive to your phone/TV (like jellyfin).
