It seems like a natural extenstion for EMC and a huge market. One industry analyst estimated (to me) that EMC owns at least 60% of the VTL market - the size of which I don't now recall?- and that would be a good way to approximate the opportunity for QTM-based dedupe with EMC i.e. dedupe with complement or leap frog the VTL market. This something Data Domain just won't really penetrate...how should I think about this?

The thought process is, where it makes the most sense, deduplicate as close to the source as possilbe. This means that leverage deduplication as early in the process as possible. For example, primary storage and soruce based backup deduplication are great fits for 'as close to the source as possible' but an Oracle database with a high transaction rate wouldn't be a good fit for 'as close to the soruce as possible'. So we are trying to define use cases that give clear direction on where you get the most bang for you buck without impacting performance. Matt – Great question.

When you say, "duplicate as close to the source as possible" how does that get applied practically between source-based and target-based dedupe. If understand it correctly even the DL line has edge-to-core capability so it could be close to the source? I like your post and think this blog is great.

Of course, having had a long history with NetWorker, and now working for one of EMC's competitors, we probably wont always see eye to eye, nonetheless, I look forward to seeing more from you on your road to recovery.
