when I am backing up the Plex Media Server folder under /var/lib/plexmediaserver/Library/Application Support/Plex Media Server, I am getting the errors similar to the following one (with different paths) on some files under ./Plex Media Server/Metadata folder.
cp: cannot create symbolic link ‘./Plex Media Server/Metadata/TV Shows/a/d3d4266c0f4dbb7801056a11f73a093e4cef98c.bundle/Contents/_combined/seasons/4/posters/com.plexapp.agents.thetvdb_5c63a7f8fe5950c250f9a0c73b5ea020ee364add’: Function not implemented
Tip!: In many cases, you may find it beneficial to “zip” or “tar” (or similar) the contents of the data directory. The larger your library, the more useful this may be for you as it could otherwise take a very long time to process thousands of individual small metadata files.
