AWS Elastic Disaster Recovery vs Commvault Microsoft 365 Backup: 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 Microsoft 365 environments need Commvault Microsoft 365 Backup because air-gapped recovery isolates your backups from ransomware that compromises production, a gap most native M365 tools don't address. The service restores up to 2TB per hour and covers Exchange, Teams, SharePoint, and OneDrive across Commercial, GCC, and GCC High tenants, meaning you're not managing separate vendor contracts. Skip this if your priority is eDiscovery over recovery speed; the search capabilities exist but aren't the competitive advantage here.
