You're doing a 100TB log backup in 50 seconds? That's simply amazing right there.

But the question I have is, with an 800TB database (which is about 800 times the size of the largest database I've dealt with), how is it possible that you have a 100tb log? That means you're moving 1/8 of the data through the log at any one time. On any scale system, that's excessive.

I'm excited to see what people have to say about this one.
