destinationRegion

The destination Region to use in the PresignedUrl parameter of a snapshot copy operation. This parameter is only valid for specifying the destination Region in a PresignedUrl parameter, where it is required.

The snapshot copy is sent to the regional endpoint that you sent the HTTP request to (for example, ec2.us-east-1.amazonaws.com). With the CLI, this is specified using the --region parameter or the default Region in your Amazon Web Services configuration file.
