    ResourceTags.N No Array of ResourceTag Array of tag key-value pairs
    DcnRegion No String If you create a disaster recovery instance, you need to use this parameter to specify the region of the associated source instance so that the disaster recovery instance can sync data with the source instance over the Data Communication Network (DCN).
    DcnInstanceId No String If you create a disaster recovery instance, you need to use this parameter to specify the ID of the associated source instance so that the disaster recovery instance can sync data with the source instance over the Data Communication Network (DCN).
