Commvault provides protection and recovery for Microsoft Azure Virtual Machines. It uses Azure-native APIs to create VM snapshots, protect Azure VM resources, and restore data at the file, disk, or VM level.
You can protect Azure workloads by using Commvault-hosted infrastructure or self-managed infrastructure. Azure VM protection supports policy-based automation, immutable storage options, cyber resilience workflows, and recovery across subscriptions and regions.

In-place restores can recreate the following Azure networking resources:
-
Virtual networks (VNets)
-
Subnets
-
Network security groups (NSGs)
-
Route table associations
-
NAT gateway associations
-
DDoS protection associations
-
Service endpoints

Restore limitations
Review the following restore limitations when planning Azure VM protection:
-
Guest file restore isn't supported for:
-
VMs that use Azure Disk Encryption (ADE)
-
Unix VMs that use Ultra Disks or Premium SSD v2 disks
-
-
Confidential VMs that use customer-managed keys (CMKs) can't be restored to a different Azure subscription or Azure geography.
-
Confidential VMs can't be restored to a different region from a snapshot copy. To restore confidential VMs to a different region, use a backup copy or streaming copy.
Platform limitations
The following Azure platform limitations can affect backup and restore operations:
-
Azure currently supports only crash-consistent snapshots for confidential VMs.
-
Azure snapshot restrictions for Ultra Disks and Premium SSD v2 disks can affect backup and restore operations.
-
Virtual Machine Scale Sets (VMSS) that use Uniform orchestration mode have Azure platform limitations that can affect backup and restore operations. For full compatibility, use Flexible orchestration mode.
