Unfortunately, I have not been able to really narrow down the problem. By disabling parts of the courses in the backup process, I’ve once been able to get an error message “Can not create local file pool file, please verify permissions in dataroot and available disk space”. However, that didn’t really help me too much either. Furthermore, it seems that multiple parts of that course cause that problem. I’ve found a part that causes it even if I just backup that part of the course, however just excluding that part does not solve the problem, thus there must be at least two of them.
