Resilience and disaster recovery in Amazon DynamoDB

The Amazon global infrastructure is built around Amazon Regions and Availability Zones. Amazon 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.

If you need to replicate your data or applications over greater geographic distances, use Amazon Local Regions. An Amazon Local Region is a single data center designed to complement an existing Amazon Region. Like all Amazon Regions, Amazon Local Regions are completely isolated from other Amazon Regions.

For more information about Amazon Regions and Availability Zones, see Amazon global infrastructure.

In addition to the Amazon global infrastructure, Amazon DynamoDB offers several features to help support your data resiliency and backup needs.

On-demand backup and restore

DynamoDB provides on-demand backup capability. It allows you to create full backups of your tables for long-term retention and archival. For more information, see On-Demand backup and restore for DynamoDB.

Point-in-time recovery

Point-in-time recovery helps protect your DynamoDB tables from accidental write or delete operations. With point in time recovery, you don't have to worry about creating, maintaining, or scheduling on-demand backups. For more information, see Point-in-time recovery for DynamoDB.
