Resilience in Amazon Backup

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

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

Amazon Backup is designed to use the Amazon 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 Amazon Backup documentation.

Amazon Backup encrypts your backup plans at rest and continuously backs them up. You can also restrict access to your backup plans using Amazon Identity and Access Management (IAM) credentials and policies. For more information, see Authentication, Access Control, and Security Best Practices in IAM.

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. Amazon 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 Amazon Backup Service Level Agreement (SLA).

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