Another interesting thought. We had thought about this one.

My testing has shown that we can create between 50K and 75K files per hour. 10 Million files at 50K files is a long time: 200 hours. Won't matter how many TB of disk pool you have... Kelly J.

Does anybody has experience with that kind of storage-pool for about 40 TB of backup data ? Does anybody use for example a "Data Domain DD460" or other systems using COS to reduce the amount of data. Thanks for help Chris
