Not a problem at all. Well the version is 1.8 that was the name of the package I had downloaded. I am not sure what kind of debugging information you are looking for? I had moodle in a test environment and installed moodle on a different server using the backup from moodle. It only restored the users, and nothing else. Everything else we just re-entered. It was a clean installation then installing the moodle backup file. I am not sure what you mean by 3rd party blocks please explain.
