Interface StartSnapshotCommandInputProtected

A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Idempotency ensures that an API request completes only once. With an idempotent request, if the original request completes successfully. The subsequent retries with the same client token return the result from the original successful request and they have no additional effect.

If you do not specify a client token, one is automatically generated by the Amazon Web Services SDK.

For more information, see Idempotency for StartSnapshot API in the Amazon Elastic Compute Cloud User Guide.

A description for the snapshot.

Indicates whether to encrypt the snapshot.

    <p>You can't specify <b>Encrypted</b> and <b>
        ParentSnapshotId</b> in the same request. If you specify both parameters, the
        request fails with <code>ValidationException</code>.</p>

    <p>The encryption status of the snapshot depends on the values that you specify for
        <b>Encrypted</b>, <b>KmsKeyArn</b>,
        and <b>ParentSnapshotId</b>, and whether your Amazon Web Services account
        is enabled for <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html#encryption-by-default">
