I'm not a fan of the per-TB licenses either, however my understanding of the NetBackup Deduplication license is that you pay per TB up front instead of on the back end, which means you don't have to pay for the DR copy (or other copies.) I haven't priced this out yet, but it will be interesting to see the 2 x DataDomain versus 1 x NetBackup Deduplication + 2 x DAS comparison. In my case we're considering converting a ton of D2D DAS hardware to this model which means I'm going to need crazy Eddie pricing from EMC to compete with sites that already have storage.

One of the selling advantages of the PureDisk appliances is that you only buy the de-dupe licenses once. All hardware eventually gets old. When that happens, you can buy another PureDisk appliance and re-use your existing de-dupe licenses. You could build your own appliance with off-the-shelf hardware and re-use the licenses. With a DD, when you upgrade the hardware, you're re-buying the software again since the prices are not separate. When you're doing the cost comparisons, factor in not only the initial purchase but also subsequent purchases. I despise per-TB licenses too (as somebody else pointed out), If I had a choice, I wouldn't buy them and would tend to avoid the PureDisk licensing model specifically for this reason. .../Ed
