Configuring Worker Instance Settings

To perform image-level backup or to restore backed-up data, you must first configure worker instance settings.

Specify an IAM role for worker instances.
Configure network settings for AWS Regions in which worker instances will be launched.

By default, Veeam Backup for AWS uses the Default Backup Restore IAM role to launch worker instances. The role is preconfigured and has all the required permissions to launch worker instances within the initial AWS account.

You can specify a different IAM role, for example, if you want Veeam Backup for AWS to launch worker instances in another AWS account. Before you specify the necessary role, make sure it is added to Veeam Backup for AWS as described in section Adding IAM Roles.

To specify an IAM role for worker instances, do the following:

Switch to the Configuration page.

Navigate to Workers > General.

Click the link to the right of Worker IAM role.

In the Choose IAM Role window, click the necessary IAM role, and then click Apply.

Important

It is not recommended that you change the specified IAM role. Otherwise, all configured worker instance settings will be automatically removed as soon as you specify another IAM role.

After you specify the IAM role, it is recommended that you check whether permissions of the specified IAM role are sufficient to launch worker instances. For information on how to check IAM role permissions, see Checking IAM Role Permissions. To learn what permissions must have the IAM role used to launch worker instances, see Service IAM Role Permissions.

Configuring Network Settings

For each AWS Region in which worker instances will be launched, you can configure network settings:

In the Worker network settings section, click Add.
Complete the Add Region wizard.

At the Region step of the wizard, select an AWS Region and Availability Zone for which you want to configure network settings.
At the Network Settings step of the wizard, select an Amazon VPC and a subnet to which you want to connect worker instances, and specify a security group that must be associated with the instances. For more information on Amazon VPC, subnets and security groups, see AWS Documentation.

Veeam Backup for AWS will apply the specified network settings to all worker instances that will be launched in the AWS Region and Availability Zone selected at the Region step of the wizard.

Important

Consider the following:

By default, Veeam Backup for AWS uses public IPv4 addresses to communicate with worker instances. If the public IPv4 addressing attribute is disabled for the selected subnet, Veeam Backup for AWS will display a warning at the Summary step of the wizard. In this case, you must either enable public IPv4 adressing for the subnet, or configure the sqs, ssm, ec2messages and ssmmessages endpoints for it to let Veeam Backup for AWS use private IPv4 addresses. To learn how to configure endpoints, see AWS Documentation.
If you select an Outpost subnet, backup and restore operations in the AWS Region to which the AWS Outpost is connected may fail to complete successfully. The issue occurs if the default worker instance class (c5.large) is not supported for the AWS Outpost. To work around the issue, contact Veeam Customer Support.

At the Summary step of the wizard, review summary information and click Finish.
