Metadata keeps filling up /var/ partition

[Huecuva]

Yeah, I've already symlinked the /var/lib/jellyfin directory to a directory on my NAS which has ample space (the NAS is the same server as the Jellyfin host, just a much bigger attached drive. The same drive where all my media is stored). I'm just wonder now if more needs to be done since /var still seems to be pretty big. Does the du command include what's in the symlinked directory and everything just gets moved automatically when the symlink is created or is there something else I need to do after creating the symlink?
