AWS Elastic Disaster Recovery vs Keepit Backup for Microsoft Entra ID: 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 security teams managing Entra ID across multiple tenants need Keepit Backup for Microsoft Entra ID because it stores identity data outside Microsoft's infrastructure, eliminating the risk of a single compromised tenant taking your backups with it. The immutable storage architecture with ransomware prevention directly addresses NIST RC.RP recovery requirements that most identity backup tools skip. Skip this if your organization treats Entra ID recovery as a nice-to-have rather than critical path; the API-only integration requires intentional deployment planning that doesn't suit teams wanting zero-touch setup.
