Review the Prerequisites and Considerations

Verify that you have met the following prerequisites and considerations:

Important: Verify If you have created a Virtual Standby (VSB) proxy on the Google Cloud. For more information about how to create a VSB proxy on Google Cloud, see Create a Virtual Standby to Google Cloud Policy.

Prerequisites

• You have a valid recovery point to create a Virtual Standby machine. The recovery points can be from one of the following tasks:
• Agent-based Windows Backup
• Host-Based Agentless Backup
• Replicate
• Replicate from a remote Recovery Point Server
• Install the system volume on the first disk. Verify that the system volume and boot volume of the source machine are on the same disk.
• Verify if you have the minimum permission to perform required VSB tasks. For more information, see Minimum Permission Required for VSB tasks.
• Virtual Standby is not supported for Linux sources. To view a list of supported operating systems, databases, and browsers, see Compatibility Matrix.
• Configure the VPC firewall setting on Google Cloud to open the related ports for inbound access, including TCP 8014 and TCP 4091.
• Verify if the Google Cloud account can access Google Cloud. Arcserve UDP does not provide the account.
• Specific Google Cloud API permissions are required for Google Cloud users to achieve control and interaction with Google Cloud for VSB to Google Cloud. For more information, see Configure IAM Granular Permissions for Service Accounts with VSB to Google Cloud.

Considerations

• Ad-hoc VSB is supported only when your backup destination is Arcserve UDP Recovery Point Server but not Local disk or shared folder.
• The system and boot volume on the source node in VSB to Google Cloud plan must be on the first disk due to Google Cloud limitation.
• The customization to TCP/IP setting cannot apply to the first network interface on Google Cloud instance due to Google Cloud limitation.
• The external IP address assignment is only available for the first network interface on Google Cloud instance.
• The customization to TCP/IP setting is only applicable to the scenario when Direct Access or VPN is configured between primary site and the Google Cloud network. Otherwise, the customization makes the Google Cloud instance inaccessible.
• Note: As a best practice, we recommend excluding files from antivirus scanning to make sure the Virtual Standby works properly. For more information, see Exclude files from Antivirus Scanning.
