resourceTypeOptInPreference

Updates the list of services along with the opt-in preferences for the Region.

If resource assignments are only based on tags, then service opt-in settings are applied. If a resource type is explicitly assigned to a backup plan, such as Amazon S3, Amazon EC2, or Amazon RDS, it will be included in the backup even if the opt-in is not enabled for that particular service. If both a resource type and tags are specified in a resource assignment, the resource type specified in the backup plan takes priority over the tag condition. Service opt-in settings are disregarded in this situation.
