You can use Commvault to perform streaming backups and recover instances or images, from the Command Center or from the CommCell Console.

OpenStack is an open source management stack that provides a consistent interface over one or more hypervisors, providing processing, storage, and networking resources through a data center or keystone node.

Key Features



Additional information

Agentless backups and restores

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


System Requirements

"Incremental forever" data protection

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



You can restore full instances or images, guest files and folders, or cinder volumes, and attach restored volumes to a different OpenStack instance.


Disaster recovery

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

Replication for Virtual Machines

Simplified operational interface

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

Command Center

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 OpenStack keystone node. You can perform backups and restores from the virtualization client, and perform other administrative tasks such as creating schedules and generating reports.

Creating a Virtualization Client for OpenStack

Automatic protection for all instances

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

Creating a Subclient

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

Automatic discovery

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

Instance Discovery and Filtering

Customized filters

To exclude instances from backups, create rules to filter instances.

Defining Filters

Instance conversion

When restoring an instance, you can choose to restore to a different hypervisor. This capability can be used to migrate instances to a different virtualization platform.

Virtual Machine Conversion


You can view information about each backed up instance, including information such as size of the data and the guest operating system.

Reports for Virtual Server Agents

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 instances 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.
