title: Unable to export RDS snapshot to S3: "This operation is not currently supported"
body: <p>I am trying to export MySQL RDS to S3 following <a href="https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ExportSnapshot.html" rel="nofollow noreferrer">Exporting DB Snapshot Data to Amazon S3 - Amazon Relational Database Service</a>.</p>
  
  <p>There are two issues:</p>
  
  <ul>
  <li><p>When I am using the steps in AWS console, I am not able to see the "For Actions, choose Export to Amazon S3" option.</p></li>
  <li><p>If I use the AWS CLI,</p></li>
  </ul>
  
  <pre><code>    aws rds start-export-task --export-task-identifier my_snapshot_export \
      --source-arn arn:aws:rds:AWS_Region:123456789012:snapshot:snapshot_name \
      --s3-bucket-name my_export_bucket \
      --iam-role-arn iam_role \
      --kms-key-id master_key
  </code></pre>
  
  <p>it gives the following error:</p>
  
  <blockquote>
    <p>An error occurred (InvalidParameterCombination) when calling the StartExportTask operation: This operation is not currently supported. </p>
