System Requirements for Virtual Server Agent with Amazon
Commvault software is supported with Amazon EC2 or VPC.
Virtual Server Agent Proxy Requirements
For backups, the Virtual Server Agent (VSA) should be installed on a Windows instance hosted in Amazon and must be located in the same region as the instances to be backed up.
The VSA proxy machine must be able to connect to ec2.amazonaws.com. To route communications through an HTTP or HTTPS proxy, provide proxy information in the CommServe Control Panel, on the HTTP Proxy tab of the Internet Options dialog box. To use an HTTPS proxy, you must provide authentication details.
For restores, the VSA proxy can be an Amazon instance or an external machine.
For IntelliSnap backups and restores from IntelliSnap jobs, the VSA proxy can be an Amazon instance or an external machine.
The VSA proxy must meet the following requirements:
- Operating system must be one of the following:
- Windows Server 2008 R2
- Windows Server 2012 R2
- Windows Server 2016
- Minimum of 100 GB disk space recommended.
- Minimum of 4 GB RAM required beyond the requirements of the operating system and running applications.
For VSA proxies running on Amazon instances, the following additional requirements apply:
- Windows Server 2012 R2 instances where the Virtual Server Agent is installed must upgrade to the latest paravirtual (PV) driver.
- EBS optimized, high IOPS volume.
- For streaming backups and backup copies, if the VSA proxy used for backups and restores is running on an Amazon instance, the proxy must be available in the same user account as the instance being backed up or restored. This requirement does not apply to IntelliSnap backups.
See the following topics for user permission requirements:
- Amazon Web Services User Permissions for Backups and Restores
- Amazon Web Services User Permissions for VM Conversion
When Amazon adds a new region, Software Development Kit upgrades are required before Commvault support can be added. For this reason, Commvault support for newly added regions will be added after the new regions are made available by Amazon. See Amazon Regions for a list of regions supported by Commvault for the current service pack.
You can limit communication across Amazon regions as described in Restricting a VSA Proxy to a Specific Region.
Guest Operating Systems
Instances being backed up can have any of the guest operating systems that are supported by the Amazon platform.
In an environment with firewalls, the following requirements apply:
- To enable installation of the Virtual Server Agent to Amazon instances and communication with the CommServe system, open tunnel ports (for example, 8400 and 8403) in the security group for the instance.
- To perform backup and restore operations using a VSA proxy on an Amazon instance, open port 443 in the security group for the VSA proxy instance.
Third-party maintenance (minor) releases or service packs that are supported by the Commvault software may not be listed in our System Requirements. When possible, Commvault provides information on any known issues related to these minor releases or service packs. In some cases, these minor releases or service packs affect how the Commvault software works. Commvault software may experience changes in functionality as the result of the third-party minor release or service pack. These changes are beyond the control of Commvault. Platforms that are supported in the current version of Commvault software may not be supported in earlier versions of the software. Contact your software provider to ensure that third-party minor releases or service packs are compatible with the Commvault software.
Additional considerations regarding minimum requirements and End-of-Life policies from third-party vendors also apply.
