Step 8. Specify Proxy Appliance
At the Proxy Appliance step of the wizard, you can specify the proxy appliance settings. A proxy appliance is an auxiliary Linux-based instance. The proxy appliance is non-persistent. Veeam Backup & Replication automatically deploys the appliance in Google Compute Engine only for the duration of the restore process and removes it immediately after that.
The proxy appliance is required if you restore machines from backups stored in external repositories or object storage repositories, and is recommended to use if you restore machines from backup repositories. During the restore process, Veeam Backup & Replication may require the proxy appliance to upload disks of a backed-up machine to Google Compute Engine.
When configuring the proxy appliance, mind the following:
- If you want to restore from backups in an on-premise object storage repository, the proxy appliance machine must have access to the source object storage repository. To provide access to object storage repositories, you can use VPN or Google Dedicated Interconnect. For more information, see the Google Cloud documentation.
- To upload one machine disk to Google Compute Engine, the proxy appliance requires 1 GB RAM. Make sure that the type of Google Compute Engine instance selected for the proxy appliance offers enough memory resources to upload all machine disks. Otherwise, the restore process may fail.
- The VPC route table must contain a route from the IP address of the Veeam Backup & Replication server to an active Google Cloud internet gateway. For more information on internet gateways and how to create route tables, see the Google Cloud documentation.
To specify proxy appliance settings, do the following:
- Select the Use the proxy appliance check box.
- Click Customize.
- From the Machine type list, select the instance type for the proxy appliance.
- From the VPC list, select the VPC network for the proxy appliance.
- From the Subnet list, select the subnet for the proxy appliance.
- In the Redirector port field, specify the port that Veeam Backup & Replication will use to route requests between the proxy appliance and backup infrastructure components.
- Click OK.
