Thank you, BetterRed.

'calibredb backup_metadata' does nothing.
'calibredb backup_metadata --all' returns an error message (attached below).
In both cases, I get the prompt back way too soon for any significant work to have been accomplished on the Calibre database.

Any other ideas would be most welcome.
