I am so sick and tired of hearing "storage is cheap." Storage is absolutely, positively, NOT CHEAP. Apparently just because the physical hard drives have reduced in price, everybody thinks that means loading up your data center with hard drives is cheap. It's not. Hard drives require power -- a lot of power because they spin. Power is not cheap. Hard drives get very hot when densely packed. Cooling is not cheap. Hard drives take up a lot of physical space, even at high densities. Do you have spare rack space you can blow on hard drives? I don't!

Deduplication should have been the very first feature implemented in DPM 2012.
