Commvault provides protection and recovery for Microsoft Hyper-V virtual machine environments. It integrates with the Hyper-V infrastructure to enable agentless backups, application-aware protection, and fast VM or file-level restores. Policy-based automation, deduplication, encryption, and immutability help protect Hyper-V virtual machines from accidental deletion, corruption, ransomware, and other cyberattacks.
