For this reason, encrypted data blocks sent to the deduplicating storage appliances appear different, even though they may contain duplicate data. Now 656MB does not equal 833MB. If we disable Veeam dedupe, Veeam will copy all 40 of the blocks to the dedupe appliance, thus copying 10MB instead of 256K, however, the dedupe appliance will deduplicate the 40 blocks, and report a dedupe ratio of 160:1.
