Linux Access Node Support for Amazon Web Services

You can configure a Linux instance to act as a Virtual Server Agent (VSA) access node for Commvault backups and restores. You can use the Linux access node for streaming or IntelliSnap backup operations and restore operations.

Requirements

• One of the following AWS instance types:

  • CentOS 7.4, 8.0

  • RHEL 7.5, 8.0, 8.2

  • Amazon Linux instance using a 64-bit Arm processor

    When you use an AWS instance with the 64-bit ARM processor as a Linux access node for VSA, you can back up instances or restore full instances, but you cannot restore guest files.

• Mono

• Commvault Virtual Server Agent package

• If you use an on-premises deployment of the CommServe system, configure a firewall as described in Configuring a Firewall to Install the Virtual Server Agent on a Cloud VM or Instance before you deploy the Linux access node.

Deployment Options

• From AWS Marketplace AMI, you can deploy the Commvault Cloud Access Node BYOL to serve as a Linux access node and as a File Recovery Enabler for Linux. This AMI contains all of the components that are required to support Linux operations in the Commvault environment. For more information, see Deploying a Commvault Linux MediaAgent from AWS.

  For more information, see Deploying the Commvault MediaAgent.

• On a CentOS instance, install Commvault Virtual Server Agent and MediaAgent packages.

  For more information, see the following pages:

  • Installing the MediaAgent

  • Getting Started with the Virtual Server Agent for Amazon Web Services

Supported Features

• IntelliSnap backups

• Streaming backups

• Instance filters

• Volume filters

• Full instance restores (HotAdd method)

• Restore volume and attach to new or existing instance

• Live browse

• Restore guest files and folders

• Agentless file recovery using Command Center

• Live sync replication (HotAdd method) when the drivers are pre-installed on the guest VMs (including failover and failback support)

The following features are not supported when using a Linux access node. Use a Windows access node for these operations.

• Full instance restores (import method)

• Conversion from another hypervisor to AWS (import method).

• Conversion from another hypervisor to AWS (import method) is not supported when using a Linux access node to convert a Windows guest VM.

• Live sync replication (import method).

  Note

  For cross-hypervisor restores or replication from VMware to Amazon, you can use an access node that runs on Windows or Linux. If you use an access node that runs on Linux, for both Windows and Linux guest VMs, the drivers must be installed on the source before performing the backup. Otherwise, the replication operation fails. You cannot use a Linux access node for the import method.
