feature

AWS Elastic Disaster Recovery (DRS) now allows configuration of the Amazon EBS volume initialization rate, enabling recovered volumes to achieve full performance faster. This feature helps I/O-intensive workloads, like databases, meet recovery time objectives by ensuring predictable storage performance during drills and full recoveries. It is available in all AWS regions and environments where the EBS initialization rate is supported, with charges based on snapshot size and specified rate.

  • Configure EBS volume initialization rate for faster recovery performance

    AWS Elastic Disaster Recovery now supports configuring the Amazon EBS volume initialization rate via EC2 launch templates. This allows recovered volumes to reach full performance faster by controlling the background data loading rate from S3, which is beneficial for I/O-intensive workloads like databases.

Enhancements (1) ›
  • Initialization rate preserved across DRS updates

    The specified EBS volume initialization rate is preserved by AWS DRS across updates made for rightsizing or disk changes on the launch template. If the rate cannot be applied during a specific recovery, DRS will proceed without it, ensuring recovery is never blocked.

Notes (1) ›
  • Availability and Pricing

    AWS DRS support for the EBS volume initialization rate is available in all AWS Regions and environments where the EBS volume initialization rate is offered. Charges apply per GB based on the full snapshot size and the specified rate.
