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.
