Commvault Microsoft 365 backup — overview
Commvault Cloud — the platform that absorbed the Metallic SaaS brand — brings enterprise data-protection heritage to Microsoft 365. Its defining characteristic is security architecture: backups are air-gapped and isolated from your tenant in a zero-trust design, with built-in anomaly and threat detection (Threatwise) to surface ransomware activity early.
It covers the full Microsoft 365 stack plus Entra ID and Dynamics 365, stores copies outside the Microsoft cloud in your chosen region (the UK is available), and — because it is the same platform Commvault uses for VMs, databases, files and endpoints — it can scale to protect your entire estate from one console rather than just SaaS.

Commvault M365 backup — FAQs
Is Metallic still a separate product?
The Metallic SaaS offering is now delivered under the Commvault Cloud platform. It is the same managed, cloud-delivered backup — the branding has consolidated under Commvault.
What makes Commvault’s security different?
Backup copies are air-gapped and isolated from the source tenant under a zero-trust model, and the platform includes Threatwise anomaly/threat detection to catch ransomware behaviour early — a more security-led posture than most.
Can Commvault protect more than Microsoft 365?
Yes. The same Commvault Cloud platform protects VMs, databases, file servers and endpoints, so M365 backup can be one part of a single estate-wide data-protection strategy.
