optionGroupName
The name of an option group to associate with the copy of the snapshot.
Specify this option if you are copying a snapshot from one Amazon Web Services Region to another, and your DB instance uses a nondefault option group. If your source DB instance uses Transparent Data Encryption for Oracle or Microsoft SQL Server, you must specify this option when copying across Amazon Web Services Regions. For more information, see Option group considerations in the Amazon RDS User Guide.
