Step 4. Specify Proxy Appliance

At the Proxy Appliance step of the wizard, you can specify the proxy appliance settings. A proxy appliance is an auxiliary instance that is necessary for transferring the data from Amazon S3 to Amazon S3 Glacier. You can specify proxy appliance settings in one of the following ways:

• Use the default settings. In that case, Veeam Backup & Replication will select the necessary settings from those available in your account, or will create for you new settings for the EC2 instance type, Amazon VPC, subnet, security group and redirector port.
• Specify the settings manually:

1. Click Customize.
2. From the EC2 instance type drop-down list, select the instance type for the proxy appliance. The EC2 instance type affects the speed and the cost of transferring the backup files to the Archive Tier of a scale-out backup repository. For information on instance types, see this Amazon article.
3. From the Amazon VPC drop-down list, select the Amazon VPC where Veeam Backup & Replication will launch the target instance. For information on the Amazon VPC, see this Amazon article. For details on the EC2 instant types used by Veeam Backup & Replication, see this Veeam KB article.
4. From the Subnet drop-down list, select the subnet for the proxy appliance.
5. From the Security group drop-down list, select a security group that will be associated with the proxy appliance. For information on security groups for Amazon VPC, see this Amazon article.
6. In the Redirector port field, specify the TCP port that Veeam Backup & Replication will use to route requests between the proxy appliance and backup infrastructure components.
7. Click OK to finish configuring the settings.
