V11 Service Pack 12


The Virtual Server Agent (VSA) for VMware provides a unified protection and recovery vehicle for all virtual machine data in your vCenter. In addition to complete protection of entire virtual machines for disaster recovery, the Virtual Server Agent provides granular backup and recovery options.

Options such as customized automatic discovery, deduplication, and reporting ensure all your virtual machine data is easily traceable and retrievable.

Note: The Virtual Server Agent may also be referred to as the Virtual Server iDataAgent.

The VSA for VMware enables you to perform backup and restores and manage virtual machine data in complex virtualized environments.

Key Features



Additional information

Agentless backups and restores

A VSA proxy manages backup and restore operations for guest VMs in your environment, eliminating the need to install agents on guest VMs.

Deployment Planning for VMware

"Incremental forever" data protection

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

Commvault uses Changed Block Tracking (CBT) to identify changes for each incremental backup.

Backups for VMware

Full integration with VMware technologies

The Virtual Server Agent builds upon VMware technologies and adds value by providing automation.

VSA uses vStorage APIs for Data Protection (VADP) for data protection, with support for all guest operating systems supported by VADP.

System Requirements

vSAN Support with the Virtual Server Agent for VMware

VDDK Support for the Virtual Server Agent with VMware

vRealize Automation Support

Capabilities for on-premises and multi-cloud environments

A modern interface provides unified support for modern storage options such as VMware Virtual Volumes (VVols) and cloud technologies.

IntelliSnap Protection for VMs on VVol or VSAN Datastores

Support for VMware Cloud on AWS

Policy-driven data protection

Policies drive operations to meet service level agreements (SLAs), with support for VMware policies and virtual machine tags.

Schedule Policies

Storage Policies

Subclient Policies

Monitoring Policies

vSphere Tag Support

Disaster recovery

Ensure that virtual machines can be recovered in the event of a disaster or other outage. DR orchestration features include planned and unplanned failovers, failback, and test boots.

Disaster Recovery for VMware

Simplified management interface

Administration of virtual machine protection uses smart defaults to reduce configuration and support self service options for end users and groups.

Virtualization Support in Command Center

Web Console

VM Lifecycle Management

Single administration point

The virtualization client serves a single point of administration for a vCenter or ESX server. All administration activities such as backups, restores, schedules, and reports can be performed from the virtualization client.

To perform backup operations, each virtualization client can include multiple proxies where the Virtual Server Agent is installed. The virtualization client also enables proxy teaming, enabling proxy failovers for fault tolerant backups. Using multiple proxies for each virtualization client makes it possible to perform backups for a large number of virtual machines in a limited backup window.

Creating a Virtualization Client

Automatic protection for all virtual machines in a vCenter

Once you configure the Virtual Server Agent for a vCenter, all virtual machines in the vCenter are automatically selected for backup. This behavior is designed to ensure all virtual machines are backed up.

Default Subclient Coverage

Application-aware backups

Protect application data without installing guest agents on virtual machines.

Application-Aware Backups

Customized discovery

To back up only specific virtual machines in a vCenter, you can define rules to discover virtual machines and automatically select them for backup. This is useful in environments where virtual machines are frequently added or removed . You can easily browse and select vCenter objects such as hosts, datastores, and resource pools as criteria for automatic discovery.

Adding Subclient Content

Customized filters

You can add filters to exclude specific virtual machines or virtual machine disks from backups. By combining discovery rules and filters, you can precisely target virtual machines for backup.

Defining Filters

Detailed status for each virtual machine backup

You can view detailed information about each backed up virtual machine on the Virtual Machine Status tab of the View Job Details dialog box. This dialog box is available from the CommCell Console when a backup job is running. It displays information such as the name of the proxy that performed the backup of the virtual machine, the size of the backup data, and the type of backup.

Viewing Virtual Machine Backup Status

vCloud backup and restore

You can protect the vCloud-specific attributes of a virtual machine and restore a virtual machine back to a vCloud.

Configuring vCloud Backup

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

Powerful snapshot management framework

The VSA snapshot management framework uses hardware orchestration to provide enhanced recovery point objectives (RPOs) and recovery time objectives (RTOs). IntelliSnap backups work in conjunction with hardware snapshot engines.

IntelliSnap backup enables you to create a point-in-time snapshot of a virtual machine by temporarily quiescing the data, taking a snapshot, and resuming live operations.

Commvault Platform Features

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



Additional information

Block-level deduplication

Deduplication enables more efficient backups by identifying and eliminating duplicate items in data protection operations.

Deduplication at the data block level compares blocks of data against each other. If a virtual machine contains blocks of data that are identical to each other, block level deduplication eliminates storage of redundant data and reduces the size of the data in storage. Deduplication dramatically reduces virtual machine backup data for copies on all media.

Changed Block Tracking (CBT) is a VMware feature that can be used to optimize backups of virtual machines by reading only the allocated and modified portions of a virtual disk. CBT is automatically enabled for virtual machines running on hardware version 7 or later.

Deduplication Overview

Built-in compression

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