This may appear like a feature request, but it becomes more of a necessity when backing up an academic institution's courses. The grade history becomes part of the record that needs to be saved, and while it CAN be saved during a manual backup, a toggle doesn't exist on this page to trigger it:
admin/settings.php?section=backups

Can you create a field in the mdl_backup_config table that allows for Grade Histories to be backed up from the automated site backup system?

Thanks very much for your help.
