Resilience in Resource Groups

Amazon Resource Groups performs automated backups to internal service resources. These backups are not user-configurable. Backups are encrypted, both at rest and in transit. Resource Groups stores customer data in Amazon DynamoDB.

The Amazon global infrastructure is built around Amazon Web Services Regions and Availability Zones. Amazon Web Services Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between Availability Zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures.

Even a complete loss of user resource groups would not result in a loss of customer data, because most customer data is replicated across Amazon Availability Zones (AZs). If you delete groups accidentally, contact Amazon Web Services Support Center.
