Ahsay Backup Amazon S3 vs Commvault Microsoft 365 Backup: Side-by-Side Comparison (2026)

Ahsay Backup Amazon S3

Mid-market and enterprise teams backing up S3 data should pick Ahsay Backup Amazon S3 for its immutable backup enforcement and multi-destination redundancy, which actually lock you into the 3-2-1 rule rather than just suggesting it. The tool covers NIST RC.RP incident recovery execution cleanly with restore drill capabilities built in, reducing the gap between backup and tested recoverability. Skip this if you need native ransomware detection or behavioral analytics layered into backup operations; Ahsay is backup-focused, not a detection tool.

Commvault Microsoft 365 Backup

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.
