Synopsis
Sometimes you have to write something based upon your experience and not so much on existing research. Whilst in the small hours of the morning your mind wanders and you start to think about things. One of those things was the recent update to the Grid format that I did for Moodle 4.0 and the struggle I had with understanding the Backup and Restore API, its complex and seems to have some quirks. And yet it is a part of an even more complex system, being Moodle itself.
