Regarding MSDP Encryption option

Hi All,

We are looking forward to have MSDP configured in our environment (Media Server working as Storage Server with 64TB of dedup pool) and use compression and encryption features of MSDP

Also for long term retention of the data, we going to move a copy of data to tapes. We are looking forward to have SLP ( with backup operation and child duplication operation to send to tapes). 

So when my data is pushed to tapes is it encrypted? If not, how can I encrypt my data to the tapes ? I cant use encryption on the policy level since that will hamper my deduplication ratios

Looking forward for your responses. thanks in advance.
