Ok but that’s a separate process to metadata editor, yes? What does the setting in metadata editor to “create NFO if missing” actually change? The backup process creates new NFOs for every single item in my library, including overwriting old ones. I have my entire library backed up to a second server, and new NFOs for every item means thousands of NFOS to sync. I just want new ones created where they don’t already exist.

It certainly is separate to the Metadata editor, and I'm not sure on the create .nfo if missing, I would guess if you went to, say a movie, with no .nfo and tried to edit metadata it would create the .nfo if missing.

The Backup process will only create what it needs to if you select Do not overwrite existing data, when you run the backup. Then when the backup spots an .nfo already in the folder it moves on to the next movie. So it should do exactly as you want.
