When recovering EBS volumes from snapshots, data loads from S3 in the background, causing slower I/O for uninitialized blocks. By setting an initialization rate on the launch template, DRS automatically applies it during recovery, enabling faster and more predictable storage performance. This is particularly useful for I/O-intensive workloads like databases where meeting recovery time objectives (RTOs) depends on consistent storage throughput. The feature is available in all AWS regions where EBS volume initialization rate is supported, with charges based on snapshot size and the specified rate. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I make EBS volumes reach full performance faster after an AWS Elastic Disaster Recovery failover? Set an EBS volume initialization rate on the DRS-managed EC2 launch template; AWS Elastic Disaster Recovery now applies it automatically when creating volumes during recovery, so storage reaches full performance on a predictable timeline instead of gradually loading blocks from S3 in the background. This is set once and preserved across rightsizing or disk changes DRS makes. _daily.dev surfaces AWS updates like this for teams tuning disaster recovery performance for databases._ ### What happens if the EBS volume initialization rate cannot be applied during an AWS DRS recovery? Recovery completes without applying the rate rather than being blocked. AWS Elastic Disaster Recovery preserves the configured initialization rate setting across template updates for rightsizing or disk changes, but if the rate cannot be applied for a particular recovery, DRS still finishes the recovery, just without that performance optimization. _Engineers designing DR runbooks track edge cases like this to avoid surprises during an actual recovery._ ### How is AWS charged for EBS volume initialization rate used with AWS Elastic Disaster Recovery? Charges are per GB, based on the full snapshot size and the initialization rate specified, following Amazon EBS pricing. This applies wherever AWS DRS support for EBS volume initialization rate is available, which spans all AWS Regions and environments where the EBS volume initialization rate feature itself is offered. _Teams budgeting disaster recovery costs on AWS can keep tabs on pricing-relevant changes via daily.dev._ ## Similar posts on daily.dev - [AWS Elastic Disaster Recovery introduces Recovery Plans for orchestrated application recovery](https://daily.dev/posts/aws-elastic-disaster-recovery-introduces-recovery-plans-for-orchestrated-application-recovery-hawrjalev) · AWS · 3 upvotes · 0 comments - [AWS Elastic Disaster Recovery is now available in the AWS European Sovereign Cloud](https://daily.dev/posts/aws-elastic-disaster-recovery-is-now-available-in-the-aws-european-sovereign-cloud-fjxuixrwx) · AWS · 0 upvotes · 0 comments - [Amazon RDS now provides visibility into storage volume initialization status](https://daily.dev/posts/amazon-rds-now-provides-visibility-into-storage-volume-initialization-status-fphgrpfa5) · AWS · 0 upvotes · 0 comments - [AWS Adds Intelligent-Tiering and Replication for S3 Tables](https://daily.dev/posts/aws-adds-intelligent-tiering-and-replication-for-s3-tables-ku8f0ksmd) · InfoQ · 0 upvotes · 0 comments --- Tags: [#aws](https://daily.dev/tags/aws) [View this post on daily.dev](https://daily.dev/posts/aws-elastic-disaster-recovery-now-supports-amazon-ebs-volume-initialization-rate-usn5mmpfn) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"AWS Elastic Disaster Recovery now supports Amazon EBS volume initialization rate","url":"https://daily.dev/posts/aws-elastic-disaster-recovery-now-supports-amazon-ebs-volume-initialization-rate-usn5mmpfn","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/aws-elastic-disaster-recovery-now-supports-amazon-ebs-volume-initialization-rate-usn5mmpfn"},"datePublished":"2026-07-14T22:04:57.438Z","dateModified":"2026-09-14T06:12:15.391Z","description":"AWS Elastic Disaster Recovery (DRS) now supports configuring the Amazon EBS volume initialization rate on DRS-managed EC2 launch templates.
