Scorm backup is created incorrectly unless the backup is done with user data and files. The backup does not contain needed files in moddata/scorm

This is probably the same problem that was reported in MDL-3570.

To fix this it is necessary to modify /mod/scorm/backuplib.php, starting in line 79, there should be
if ($status) {
if (backup_userdata_selected($preferences,'scorm',$scorm->id))

{ $status = backup_scorm_scoes_track($bf,$preferences,$scorm->id); }

$status = backup_scorm_files_instance($bf,$preferences,$scorm->id);
}

instead of
if ($status) {
if (backup_userdata_selected($preferences,'scorm',$scorm->id))

{ $status = backup_scorm_scoes_track($bf,$preferences,$scorm->id); $status = backup_scorm_files_instance($bf,$preferences,$scorm->id); }

}
