I did this podcast a few months ago, but it's now available on searchstorage.com. It's always interesting to hear what I said a few months ago to see if I still agree with it.
I listened to it to see if I still agree with myself. I'd say there are two areas that have changed a bit. The first is that I'm starting to think about backup verification instead of having an extra copy on tape for risk mitigation. There's also now the first dedupe filer for primary data. (In the podcast I mention that the story isn't as compelling in primary storage. I stand by that, but it looks like NetApp's still got a pretty good story on the NearStore dedupe product.)
