AWS Elastic Disaster Recovery

Overview

AWS DRS can recover applications from physical servers, VMware vSphere, Microsoft Hyper-V, and other cloud providers. Recovery launches can use the latest server state or a selected earlier point in time, and target EC2 instances in another Availability Zone or AWS Region. After recovery, teams can replicate data back to the primary site and fail back when ready.

Non-disruptive drills let teams exercise recovery and failback while replication continues. Point-in-time recovery can also help restore an operational copy from before a security incident. These capabilities address recovery and validation, but AWS DRS does not provide failover orchestration, so teams needing coordinated failover should account for that gap.

Key features

Replication, recovery, and failback

Continuous replication supports recovery launches from current or earlier server states. AWS DRS supports workloads on supported Windows and Linux versions, including Oracle, MySQL, SQL Server, and SAP. Failback is supported, and recovery runbooks are available; failback orchestration is also supported.

Network and launch controls

Network recovery can replicate subnet CIDRs, security groups, route tables, internet gateways, and network ACLs. Post-launch actions can run AWS Systems Manager commands or automations, including predefined options such as installing a CloudWatch agent. These controls help carry infrastructure context into recovery, while requiring teams to plan their AWS target environment.

Security and connectivity

Replication data is encrypted in transit with TLS 1.2 and can use Amazon EBS encryption at rest. Replication can travel over VPN, AWS Direct Connect, or VPC peering, giving teams private connectivity options for data movement.

Scale and support

AWS DRS supports up to 300 servers replicating into one staging account, or up to 3,000 servers in one target account using multiple staging accounts. That distinction makes account design relevant as deployments grow. AWS recommends Business or Enterprise Support for production workloads, a cost and support consideration for teams running critical recovery plans.

Pricing

The AWS Elastic Disaster Recovery plan is 0.03 USD per month, billed at $0.028 per source server per hour. It includes continuous data replication, test launches, recovery launches, and point-in-time recovery. Additional AWS resource charges apply, so the per-server replication rate is not the full cost of operating recovery capacity. There is no free plan.

This paid plan suits teams that want the listed replication and recovery functions together rather than a reduced tier. Teams should account for source-server hours and AWS resources used in recovery, and production teams should consider the recommended Business or Enterprise Support.

Platforms

AWS DRS is a hybrid deployment with API, Linux, web, and Windows platform support. Its recovery destinations are EC2 instances in another Availability Zone or Region, making AWS the destination for recovered applications even when the source infrastructure is elsewhere.

Who it's for

AWS DRS fits organizations with Windows or Linux applications and databases that need recovery on AWS, including teams moving from physical, VMware, Hyper-V, or other cloud environments. It is particularly suitable when teams value ongoing replication, point-in-time recovery, failback, and non-disruptive drills and can manage AWS networking, support, and resource costs.

It is a weaker fit for teams seeking failover orchestration or recovery that does not land on AWS. The staging-account scale model also deserves attention for large fleets: beyond 300 servers in one staging account, reaching the stated 3,000-server scale requires multiple staging accounts.

Pros and cons

Pros

• Continuous replication includes test launches, recovery launches, and point-in-time recovery, supporting both routine drills and recovery from an earlier server state.
• Recovery spans physical, VMware, Hyper-V, and other cloud sources, while targeting EC2 across Availability Zones or Regions.
• Failback, runbooks, network-setting replication, and Systems Manager post-launch actions support the return path and recovery setup.
• Private connectivity options and encryption in transit, with optional EBS encryption at rest, address important data-transfer controls.

Cons

• Failover orchestration is not included, leaving coordinated failover to other processes or tools.
• Additional AWS resource charges mean the source-server rate does not capture the full cost.
• Scale into one staging account is capped at 300 servers; larger deployments use multiple staging accounts to reach the 3,000-server target-account limit.
• AWS recommends Business or Enterprise Support for production use, which teams should include in their operating plans.

Alternatives

Disaster Recovery Software is a useful starting point for comparing options across the category.

• Trilio Site Recovery is worth considering for teams seeking a Linux, API, self-hosted option; its Technology Preview / Early Adopter Program is subscription-based.
• Axcient x360Recover may suit teams seeking broader endpoint platform coverage, including macOS and Windows, and a free trial; its Direct-to-Cloud rates vary by endpoint type.
• StorPool Disaster Recovery Engine is an alternative for teams looking for a Linux, self-hosted storage-oriented option with pay-as-you-grow pricing based on saved data.
• Zerto is another paid option, with a free trial and an Enterprise Cloud Edition covering disaster recovery, backup, and long-term retention.
• Veeam Agent for Mac is a macOS alternative with a free edition, but that edition is limited to one backup job and excludes direct backup to object storage.
• Veeam Recovery Orchestrator has free NFR and evaluation licenses, as well as a free trial; its NFR license is for demonstration, training, and education, not commercial use.
• Veeam Kasten for Kubernetes offers a free plan capped at five nodes and an Enterprise Trial for 500 nodes over 60 days, making its stated scope Kubernetes-specific.
• Datto Endpoint Backup for Windows uses consumption-based pricing tied to storage used and supports Linux, macOS, web, and Windows.

Verdict

AWS Elastic Disaster Recovery is a strong choice for teams that need to recover supported workloads onto AWS and want continuous replication, point-in-time recovery, drills, and a supported failback path. Its main trade-offs are the lack of failover orchestration and the additional AWS resource charges; teams that need coordinated orchestration or a non-AWS recovery destination should look elsewhere.
