The gradebook items added through GBPV2 are not included in the automated or manual backups of Moodle. This is fairly major since backups of a course are missing a major portion of the gradebook if GBPV2 is being utilized. At first glance it appears to be related to the fact that the events are not added like other items. This item it not added to the modules table which is used to parse through the course and backup items.

If GBPV2 were modified to act like a full module (with an ID in the table as well) then the backup and restore would probably work as well. I would like to suggest that GBPV2 become part of the 1.84 core code as well. Thanks, Brian
