Encryption is done outboard in the drive, just like drive compression is done 
outboard in the drive.
No impact on backup or restore performance.

How much performance degradation would there if encryption is on? Although it 
is the duty of drive itself (I suppose), it might have negative influence on 
backup and even restore performance?
