AWS Elastic Disaster Recovery vs Cohesity NetBackup Appliances: Side-by-Side Comparison (2026)

Teams running mission-critical applications on AWS who need sub-hour recovery times without buying dedicated disaster recovery infrastructure should start here; AWS Elastic Disaster Recovery eliminates the capital expense of standby hardware by recovering directly into AWS at scale, and the free tier lets you test failover before committing. The service handles continuous replication of on-premises and cloud servers, so your RTO is limited by your network throughput, not your backup window. Skip this if your applications live outside AWS or if you need orchestrated failover across multiple cloud regions; Elastic Disaster Recovery is AWS-centric by design. Mid-market and enterprise teams managing ransomware risk at scale need Cohesity NetBackup Appliances because the Isolated Recovery Environment (IRE) actually isolates backups from the production network instead of just claiming to. Support for 800+ workloads means you're not swapping backup vendors when you adopt Kubernetes or migrate workloads, and the multi-layer security architecture addresses both PR.DS and PR.IR under NIST CSF 2.0. Skip this if your primary concern is point-in-time granularity for databases; Cohesity prioritizes recoverability and ransomware resilience over transaction-level recovery windows.

Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
