Trying to restore a backup of a course from one Moodle instance to a second Moodle instance with the same codebase (2.0.2+, set up a week or two ago) fails at step 2 with the following error message:
- line 242 of /backup/util/helper/backup_general_helper.class.php: backup_helper_exception thrown
- line 177 of /backup/util/ui/restore_ui_stage.class.php: call to backup_general_helper::detect_backup_format()
- line 56 of /backup/restore.php: call to restore_ui_stage_confirm->display()
The backup in question is a partial course backup (a couple of topics), without user data, deliberately excluding all quizzes (given the unresolved issues with quiz question backups noted previously in this forum), taken from a file-system repository that I set up so I could FTP the large backup file (120MB) to the new instance. Any help or advice that might be offered would be greatly appreciated.
