First of all, props to Jeff for this blog post. He put himself in an embarrassing situation, but handled it gracefully, without excuses. Well done. That said

First of all, props to Jeff for this blog post. He put himself in an embarrassing situation, but handled it gracefully, without excuses. Well done. That said, I don't think the post is defensive at all. It's not that Jeff made "one stupid mistake" and everybody is jumping on him-- it's that Jeff has been dispensing advice about best practices, including backups, and failed (spectacularly) on a very basic point.
