Microsoft Azure

You can use Commvault to back up and recover Azure VMs, to convert VMs to a different hypervisor, and to provision and manage VMs.

Key Features



Additional information

Agentless backups and restores

Install the Virtual Server Agent on a machine to act as a VSA proxy. A VSA proxy manages backup and restore operations for guest VMs in your environment, eliminating the need to install agents on guest VMs.


System Requirements

"Incremental forever" data protection

After an initial full backup, you can perform ongoing incremental backups to capture changes for source VMs.


Changed Block Tracking

Commvault uses Changed Block Tracking (CBT) to identify changes for each incremental backup and to reduce the time required for incremental backups.

Changed Block Tracking


You can restore full virtual machines or guest files and folders, or restore a VM disk and attach it to an existing Azure VM.


Disaster recovery

Replicate VMs to a warm recovery site to ensure that VMs are available in the event of a disaster or other outage. DR orchestration features include planned or unplanned failovers and failbacks.


Simplified operational interface

The web-based Command Center interface uses smart defaults to simplify configuration and support streamlined operations.

Command Center

Self service for end users

The Web Console provides self service options for end users and groups.

Web Console

VM provisioning

End users can use the Web Console to provision VMs based on pre-defined templates.

This feature is available only for Azure Classic.

VM Lifecycle Management

Advanced administration

The CommCell Console provides advanced options for Commvault operations.

Using the CommCell Console, you can configure a virtualization client that serves as a single point of administration for an Azure subscription. You can perform backups and restores from the virtualization client, and perform other administrative tasks such as creating schedules and generating reports.

Creating a Microsoft Azure Client

Automatic protection for all virtual machines

By default, all virtual machines are automatically selected for backup, to ensure that all virtual machines are backed up.

Default Subclient Coverage

Application-aware backups

Perform application-consistent backups without manually installing application agents on virtual machines.

From the Command Center, you can use the Auto discover applications option to automatically find applications on servers and install the agents that can back up the applications. (For more information, see Automatic Discovery of Applications in the Command Center.)

Application-Aware Backups

Cost management

Reduce costs by using storage tiering, deduplication, and power management.

Tiered Storage for Extended Retention using Cloud Libraries

Cloud MediaAgent Power Management

Automatic discovery

To back up categories of virtual machines, you can create rules to automatically select virtual machines based on specific criteria. Automatic discovery is useful in environments where virtual machines are frequently added or removed.

Automatic Discovery and Filtering

Customized filters

To exclude virtual machines from the backup, create rules to filter virtual machines.

Defining Filters

VM conversion

When restoring a VM, you can choose to restore to a different hypervisor. This capability can be used to migrate VMs to a different virtualization platform.

Virtual Machine Conversion


You can view detailed information about each backed up virtual machine, including information such as size of the data, guest operating system, and the host on which the virtual machine is running.

Reports for Virtual Server Agents

Snapshot support

Use Azure snapshots to capture virtual machine data quickly, with minimal impact on the source VM, and use the snapshot as a source for backup copies.

Commvault Platform Features

The following features are available throughout Commvault and are not limited to the Virtual Server Agent.



Additional information

Policy-driven data protection

Policies drive operations to meet service level agreements (SLAs).

Schedule Policies

Storage Policies

Subclient Policies

Monitoring Policies

Block-level deduplication

Block-level deduplication compares blocks of data during backups. If virtual machines contain identical blocks of data, block-level deduplication eliminates the storage of redundant data and reduces the size of data in storage.

Deduplication Overview

Built-in compression

Commvault storage policies automatically enable compression to reduce the quantity of data sent to storage.
