CST VerdictShort answer
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 facing ransomware threats need FortKnox because its air-gapped virtual vault makes encrypted backups genuinely unreachable during active attacks, not just theoretically so. The immutable snapshots with retention locks address NIST PR.DS and RC.RP functions that most backup tools treat as afterthoughts, while integrated threat scanning before restore prevents you from recovering compromised data. Skip this if your organization can tolerate a longer recovery window; the isolation model trades some restore speed for the certainty that your backup tier stays isolated even when production infrastructure is already encrypted.
