AWS Config adds the ability to specify a data retention policy for your configuration items

AWS Config now enables you to delete your data by specifying a retention period for your configuration items. When you specify a retention period, AWS Config retains your configuration items for that specified period. You can choose a period between a minimum of 30 days and a maximum of 7 years (2,557 days). AWS Config automatically deletes configuration items older than your specified retention period. If you don’t specify a retention period, AWS Config continues to store configuration items for the default period of 7 years (2,557 days).

This capability is available in all commercial AWS Regions where AWS Config is offered and in the AWS GovCloud (US) Region. To see the full list of supported Regions, see AWS Regions and Endpoints in the AWS General Reference.
