We just started running into a strange issue with our automated backups. I noticed they stopped running a few nights ago and after digging into the logs I have found the error but I cannot find what it means. The backups stop on one course with the error:
Default exception handler: error/setting_already_added Debug:
Error code: setting_already_added

I am not sure what to make of this. If I execute the automated_backups.php by hand (instead of cron, but the user is the same) it works just fine and the course that is causing this error even gets backed up without issue. Just wondering if anyone here might have an idea as to what is going on here. Thanks!
