What is deduplication and how does it work? (Backup to Basics series)

In our latest episode of the Backup to Basics series, we talk about what I think is the most important invention in my career: deduplication. Without dedupe, much of what we do in backup and recovery, and disaster recovery, would simply not be possible. Without dedupe there really is no disk backup market; there is no cloud backup market. I'd be out of a job! What is dedupe, anyway, and how does it work? What are the different kinds of dedupe and does that matter? You should learn a lot about this important topic.
