Resilience in AWS Backup

AWS Backup takes its resilience — and your data security — extremely seriously.

AWS Backup stores your backups with at least as much resilience and durability as your resource’s original AWS service would give you, if you backed it up there.

AWS Backup is designed to use the AWS global infrastructure to replicate your backups across multiple Availability Zones for durability of 99.999999999% (11 nines) in any given year, provided that you adhere to the current AWS Backup documentation.

The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. AWS Backup stores your backups across Availability Zones. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures. For more information, see AWS Backup Service Level Agreement (SLA).

Furthermore, AWS Backup empowers you to copy your backups across Regions for even greater resilience. For more information about the AWS Backup cross-region copy feature, see Creating a Backup Copy.
