As I was saying in my requirement list, one of the main objectives is to have integration with NetBackup OST. Now, only few vendors have that - DataDomain, Sepaton, FalconStor, Quantum, Copan (OEM of FalconStor), Diligent/IBM
I had taken each of these individually and compared their features as to what they claim they can do and can they meet my requirements. Based on that FalconStor came out on top of the list.

Thanks so much for this great post! I have been trying to learn all about data deduplication so I can understand it better. It is so awesome how this chart works and can provide you with that information! I know it can be a confusing subject for most. Can you tell me where I can find more information on this?
