Flash expert schools Mr. Backup

A few weeks ago, Mr. Backup (W. Curtis Preston) said he didn't understand why people used flash for backups. He said it was overkill. A few days later, Howard Marks of Vast (friend of the pod) took issue with that statement, and asked for the chance to defend Vast's title, so to speak. Howard is a friend of the pod and we were happy to say yes. We also take the opportunity to get an update on Vast, and discuss their data reduction techniques in more detail. Bonus points if you get the cover art reference.
