AWS Backup supports new options for customizing backup selections
AWS Backup now supports service opt-in, enabling AWS customers to opt into (or out of) AWS Backup support for supported AWS services at the account level. Service opt-in provides an easy-to-configure solution to ensure that AWS Backup service coverage reflects exactly what you need. It will also make it easy for customers to opt-in when AWS Backup introduces support for a new service, without having to change tagging strategies. Service opt-in is available in all regions where AWS Backup is available except BJS (Beijing) and ZHY (Ningxia).
