Gasp...why is this not in the manual?
Calibre Library->Library Maintenance->Library metadata backup status->Queue all books for backup

That is ONLY a backup of the CALIBRE shown METADATA. It exists to restore the DB ENTRIES only. If you want a FULL backup (best done to a different hard drive), use Export / Import on the Library icon.
