What is a key feature of AWS's disaster recovery strategy?

A key feature of AWS's disaster recovery strategy is the regular data replication across regions and availability zones. This approach enhances data durability and availability by ensuring that copies of data are stored in multiple locations. In the event of a failure or disaster in one region or zone, the data can be quickly and easily accessed from another, minimizing downtime and data loss. This broad geographic distribution is crucial for businesses that require high availability and resilience, allowing them to operate continuously even during outages or natural disasters.

The practice of regular replication helps maintain up-to-date copies of data, which can be essential for recovery processes. It supports various disaster recovery models, such as pilot light, warm standby, and multi-site active deployments, providing organizations with flexible options based on their specific needs and budget.

In contrast, the other options lack comprehensive features or do not align with AWS's best practices for disaster recovery. For example, relying solely on single region backup storage does not provide the needed redundancy, while user-managed backup solutions alone may not ensure timely recovery without automation and management features that AWS offers. Automatic data deletion policies are not a primary focus of disaster recovery but rather part of data lifecycle management.
