Given a running Plex Media Server on an Ubuntu 16.04, what information would I loose, if I backup just…
/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases
…instead of the whole folder…
/var/lib/plexmediaserver/*
Or in other words, what kind of information is exactly contained in
/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases?
I created a script I can use to backup all data and all metadata.
Keep in mind you will need to change {destination} and the source of your data.
I run this script once in a while to create a backup. The next time you run it it will be faster.
I am not sure what all is contained in the 2nd part of the script. It is not that big. I have used it to restore my server on a different Ubuntu install. It works great. It will save all metadata and all settings. It may not be the best method. But it works for me.
I have had issues in the past trying to back it up when the server is running. So now my script will stop the server for a short time as the backup is made.
