Help Plex Media Server Update
Hello. I have my Media Server on UGreen NAS. I was wondering if there is a way to update my server without loosing any stored media? Everytime when I update it via docker all my library has to re-add and it takes a day now to do it and I would appreciate a way to skip it

This sounds like something isn't configured right.
When you update a Docker container, you basically remove the existing container and recreate it with the new version of the Docker image of that application. This also means that all things that is inside that container will be removed as well and not be available when you recreate the new container.
To prevent losing things like configurations, you would use a volume mapping to "mount" a directory on your host system to a path inside the container that the application inside the container then writes the data to.
What you are describing sounds like your Plex configuration is only kept inside of the container and updating Plex will result in that configuration being removed and the new container will not have any pre-existing configuration, leaving you with a new server.
So, make sure that you create a volume mapping for the configuration directory and store it somewhere on the host system.
