I’m a good chemist, but not IT advanced. Started using Debian out of the box last year on miniPC. Running Jellyfin only on that local machine. Don’t understand coding, but copy/ paste terminal instructions from trusted sites. Have 1TB music, films and documents. Want to move all photos from Google.
To move your photos from google I recommend Immich. Is available as a docker container, or yunohost though don’t use the official yunohost version there is a better version that supports HEIC and some other formats. You can find that here though
https://codeberg.org/Loowiz/immich-docker_ynh
It is still easily installed using yunohost but upgrades are manual
But for gods sake use proper backups. The tendency for immich to break things is the reason I nowadays recommend photoprism to people who start with selfhosting - it’s worse in a lot of ways but way more stable most of the times.
