You can install a Commvault Cloud backup gateway on a Google Cloud (GC) VM to back up Google Cloud instances from one or more projects in the same region. The backup gateway is deployed within your Google Cloud environment, in a VPC (Virtual Private Cloud) that you select to host the gateway and manage its network connectivity.
Access Nodes
Planning for protection of your Google Cloud VMs with Commvault Cloud includes verifying that your environment meets the system requirements and configuring access to the resources you want to protect. This process involves setting up access nodes, which must have the Virtual Server Agent package installed, and adding a hypervisor to manage the backups. For information on how to add a hypervisor and install the access node, see Configuring Backups for Google Cloud Instances.
Access Node Network Requirements
To back up resources from one or more Google Cloud projects, you must install at least one Commvault Cloud access node on a Google Cloud Compute Engine instance.
Sizing Recommendations
Commvault recommends using the N2 machine series listed below for your access nodes:
-
n2-highmem-2, indicative cost USD$118.36/month Iowa (us-central1)
-
n2-highmem-4, indicative cost USD$253.03/month Iowa (us-central1)
-
n2-highmem-8, indicative cost USD$468.36/month Iowa (us-central1)
Additional Information
-
For the latest pricing information on the N2 machine series, refer to the Google Cloud pricing calculator.
-
For the minimum vCPU/RAM specifications to consider when selecting alternative machine series types, refer to the Storage Requirements.
Deployment
Commvault Cloud does not currently offer a pre-configured access node image in Google Cloud. You can deploy a Compute Engine instance from the Google Cloud Marketplace with your preferred, Commvault-supported operating system, and then install the Commvault Cloud software.
Access Node Location
You must have at least one (1) access node per Google Cloud Region you want to protect.
Access Node Availability
Commvault recommends deploying at least two (2) access nodes, in separate zones, to increase the availability and resilience of your Google Cloud backup and recovery operations. For information on how to set an access node group on the hypervisor, see Configuring Backups for Google Cloud Instances.
Operating System Support
Ensure you install the Commvault Cloud Virtual Server Agent (VSA) corresponding to your CommServer version.
Access nodes for Google Cloud instances must run one of the supported operating systems listed below:
Linux
-
Live browse operations using Linux access nodes are supported only for the NTFS file system.
-
Live browse operations using Linux access nodes are not supported for snapshot-based backups.
-
Restoring files with advanced encryption attributes using a Linux access nodes is not supported.
-
Install the Virtual Server Agent on a Linux machine that runs any of the following operating systems:
-
Rocky Linux 9.x, 8.x, (recommended)
-
Red Hat Enterprise Linux (RHEL) 9.x, 8.x
-
Oracle Enterprise Linux (OEL) 9.x, 8.x
-
-
End of Life (best effort support)
-
CentOS Linux 7.9, 7.8, 7.7, 7.6, 7.5, 7.4
-
Red Hat Enterprise Linux (RHEL) 7.x, see What to know about Red Hat Enteprise Linux 7 End of Maintenance
-
Oracle Enterprise Linux (OEL) 7.x, see Extend your OS upgrade timeline: Oracle Linux 7's Extended Support with expanded coverage)
-
Windows
-
A Windows access node is required only to protect compute instances that use dynamic disks, the ReFS file system, or disk encryption.
-
A Windows access node cannot perform live browse operations for EXT3, EXT4, and XFS file systems.
-
The ACL of NTFS files is preserved during cross-platform restores only if the destination client is installed with Windows.
-
Commvault supports Microsoft Windows Server Standard, DataCenter, and Core editions:
-
Microsoft Windows Server 2025 x64
-
Microsoft Windows Server 2022 x64
-
Microsoft Windows Server 2019 x64
-
Microsoft Windows Server 2016 x64
-
Architecture
Commvault Cloud supports the deployment of access nodes and MediaAgents on the following chipset architectures:
-
Arm (recommended)
-
x86-64 (Intel, AMD)
Network Requirements
-
The access node must have outbound access to the following URLs:
-
https://compute.googleapis.com
-
https://content-cloudkms.googleapis.com
-
https://cloudresourcemanager.googleapis.com
-
https://storage.googleapis.com
-
-
The access node security group must have outbound access to the CommServer and MediaAgents on TCP ports 8400 and 8403.
Network Gateway Requirements
If the access node cannot reach the Commvault Commserver or MediaAgent(s) directly, you must create one or network proxies to proxy traffic from your Google Cloud VPC to your Commvault Cloud infrastructure. To connect to the proxies and domains that are associated with your Commvault Cloud environment, see Network Connectivity.
HTTP/HTTPS Proxy Requirements
You can access the internet by configuring the HTTP/HTTPS proxy to access Google Cloud service endpoints. See, Using an HTTP Proxy to Access the Internet.
Configuring a Firewall to Install the VSA
To deploy Commvault Cloud software to an access node, when other components (such as the CommServer) are on premises, configure a firewall for an access node in the cloud between the on-premises components and the cloud VM or instance.
Storage Requirements
Commvault Cloud requires that Google Cloud access nodes meet the following minimum specification:
|
Components |
Extra Small |
Small |
Medium |
|---|---|---|---|
|
CPU/RAM |
2 vCPUs/16 GiB |
4 vCPUs/24 GB |
8 vCPUs/32 GB |
|
Front End Terabytes (FET) |
110 TiB |
25 TiB |
50 TB |
Front-End Terabytes (FET) refers to the amount of file-system data written to the compute instance(s) configured for backup. Commvault recommends not exceeding the vCPU/RAM specifications of a Medium instance. Instead, scale horizontally by adding more access nodes.
DISCLAIMER
Certain third-party software and service releases (together, "Releases") may not be supported by Commvault. You are solely responsible for ensuring Commvault’s products and services are compatible with any such Releases.
