Amazon: System Requirements
To provide better throughput for streaming backup and backup copy operations, use a compute-optimized instance hosted in Amazon. For more information, see Amazon EC2 Instance Types.
The VSA proxy must be in the same Amazon account and located in the same region as the instances to be backed up.
Note: In a deployment that uses resources from an admin account, the VSA proxy (access node) can be in the admin account, but must be in the same region as the instances to be backed up. For more information, see Using Resources from an Admin Account.
For VM conversion and 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:
- The VSA proxy machine must be one of the following types of machines:
- Windows Server 2019
- Windows Server 2016
- Windows Server 2012 R2
- For Linux proxy support, configure a VSA proxy on a Linux instance using either of the following methods:
- Deploy an AWS Marketplace AMI to serve as a Virtual Server Agent proxy for Amazon.
- Configure a CentOS 7.4, CentOS 8, RHEL 7.5, or RHEL 8 instance with the required software.
Note: For CentOS 8 or RHEL 8 instances, to install operating system packages that are required to enable automatic installation of Mono, register the instances with CentOS or Red Hat.
- Configure an AWS Linux instance that uses a 64-bit Arm processor with the required software.
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.
For more information, see Linux Proxy Support for Amazon Web Services.
- Minimum of 100 GB disk space recommended.
- Minimum of 4 GB RAM required beyond the requirements of the operating system and running applications.
- The VSA proxy machine must be able to connect to ec2.amazonaws.com, or the regional equivalent if the Amazon account is restricted to specific regions. 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 VSA proxies running on Amazon instances, the following additional requirements apply:
- Windows Server 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.
The Virtual Server Agent requires Layer 3 network connectivity to the upstream MediaAgent on port 8403. If the MediaAgent and the access node (VSA proxy) are in different accounts or in different Virtual Private Clouds (VPCs), you can configure Amazon VPC peering as described in the AWS article VPC peering basics.
