parentSnapshotId

The ID of the parent snapshot. If there is no parent snapshot, or if you are creating the first snapshot for an on-premises volume, omit this parameter.

You can't specify ParentSnapshotId and Encrypted in the same request. If you specify both parameters, the request fails with ValidationException.

The encryption status of the snapshot depends on the values that you specify for Encrypted, KmsKeyArn, and ParentSnapshotId, and whether your Amazon Web Services account is enabled for encryption by default. For more information, see Using encryption in the Amazon Elastic Compute Cloud User Guide.

If you specify an encrypted parent snapshot, you must have permission to use the KMS key that was used to encrypt the parent snapshot. For more information, see Permissions to use Key Management Service keys in the Amazon Elastic Compute Cloud User Guide.
