How to Assign Permissions to Service Accounts Used by Veeam Backup for Google Cloud Platform

To apply the necessary permissions to a service account:

• You can use a script that is automatically generated while adding the project to the Veeam Backup for Google Cloud infrastructure. Download the script and run it under an account that has permissions both to get and set project IAM policies and to create custom IAM roles (for example, it can have the iam.securityAdmin and iam.roleAdmin roles assigned). To learn what permissions and roles are required to create custom roles in IAM, see Google Cloud documentation.

• You can assign the permissions to the service account manually. Refer to: Service Account Permissions
