Specifies whether the destination snapshot should be encrypted. You can encrypt a copy of an unencrypted snapshot using this flag, but you cannot use it to create an unencrypted copy from an encrypted snapshot. Your default CMK for EBS is used unless a non-default AWS Key Management Service (AWS KMS) CMK is specified with KmsKeyId. For more information, see Amazon EBS Encryption (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html) in the Amazon Elastic Compute Cloud User Guide.
