What kind of crap server is that? How on earth do I connect to it or set up a connection so I can access it from anywhere?
The nature of self hosting is that you’re doing the things yourself. With a service like Google photos you don’t even think about this stuff because someone else manages and figured the things out already for you.
This is good, lets you see if you are up for it when things don’t work out of the box exactly like you wanted. If it’s too much then I suggest you use a managed service.
Otherwise, then I suggest you begin with checking out tailscale. Tailscale is not exactly a selfhosted service but it’s the easiest path for SECURE remote access I can think of.
But as the other reply said, do you really need remote access? I mean, you can simply do the backups when you are connected to your home network…
Being tethered to USB each time even if you want to copy or view 1 photo will get incredibly annoying.
Immich will also give you lots of useful features like albums, tags, filtering, face detection (local), and supports multiple devices and users (do you have enough USB ports? :p) . These small features will turn more and more useful as your library grows.
You can first keep Immich working in your local network while you figure out tailscale, flexibility is a strong suit here.
