For all the posters saying Google Photos: make sure you have a backup of your originals. Google strips most of the metadata from your images when you pull down a Takeout or use the photos API, including GPS.

You can copy your original images and videos directly to a home computer/server/desktop/raspberry pi via either SyncThing or Resilio Sync.

If you want to self-host your library, there are a bunch of options, but (being the author) I'm partial to PhotoStructure: https://photostructure.com/faq/why-photostructure/

(I've had several beta users tell me that they've "tried them all" and picked PhotoStructure, but there's some survivorship bias there!)
