Hi, The data needs to be stored somewhere, and usually we need to have a server, disk array, disks, and more data means more disks, and more disks active means more power usage , therefore higher costs, and less green IT :) So, at my point of view, deduplication is relevant for lowering costs, but in order to do that , there has to be a way to measure those costs/savings. But yes, this costs probably represent less than 20% of the total cost, but its a cost no matter what.
However, maybe im driving in the wrong road...
