Verify that your environment meets the requirements for protecting Azure Stack Hub VMs with Commvault.
Azure Stack Hub Version
Azure Stack Hub 2002 and more recent versions are supported.
To protect Azure Stack Hub virtual machines, you must upgrade your CommCell environment to Commvault version 11.20 or a more recent release, and you must upgrade all of your Azure Stack Hub virtual machines to Azure Stack Hub 2002 or a more recent release. Using previous versions of Azure Stack Hub with previous versions of the Commvault software is possible. However, with those previous versions, a known Microsoft issue with snapshots of unmanaged VMs can cause data corruption. To avoid data corruption, you must upgrade both your CommCell environment and your Azure Stack Hub environment.
You must have at least 1 access node for Azure Stack Hub.
For best results, deploy access nodes on virtual machines in the Azure Stack Hub cloud. For faster backups, deploy access nodes on an Azure Stack Hub VM that is compute-optimized.
If you have existing access nodes that are used to support Azure Classic or Azure Resource Manager, use different proxies for Azure Stack Hub.
Azure Stack Hub access nodes must meet the following requirements:
Must run one of the following operating systems:
Microsoft Windows Server 2022 Editions
Microsoft Windows Server 2019 Editions
Microsoft Windows Server 2016 Editions
Microsoft Windows Server 2012 R2 Editions
Must have a minimum of 100 GB disk space.
Must have a minimum of 4 GB RAM, beyond the requirements of the operating system and any other running applications. For more information, see Sizes for virtual machines in Azure Stack Hub in the Microsoft documentation.
Must have Azure PowerShell installed and Azure Stack Hub tools downloaded.
If deployed on a virtual machine in Azure Stack Hub, must have a public IP address.
