Using roles for restore testing - Amazon Backup
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Using roles for restore testing

Amazon Backup uses Amazon Identity and Access Management (IAM) service-linked roles. A service-linked role is a unique type of IAM role that is linked directly to Amazon Backup. Service-linked roles are predefined by Amazon Backup and include all the permissions that the service requires to call other Amazon services on your behalf.

A service-linked role makes setting up Amazon Backup easier because you don’t have to manually add the necessary permissions. Amazon Backup defines the permissions of its service-linked roles, and unless defined otherwise, only Amazon Backup can assume its roles. The defined permissions include the trust policy and the permissions policy, and that permissions policy cannot be attached to any other IAM entity.

You can delete a service-linked role only after first deleting its related resources. This protects your Amazon Backup resources because you can't inadvertently remove permission to access the resources.

For information about other services that support service-linked roles, see Amazon Services That Work with IAM and look for the services that have Yes in the Service-Linked Role column. Choose a Yes with a link to view the service-linked role documentation for that service.

Service-linked role permissions for Amazon Backup

Amazon Backup uses the service-linked role named AWSServiceRolePolicyForBackupRestoreTesting – Provides backup permissions to conduct restore testing.

The AWSServiceRolePolicyForBackupRestoreTesting service-linked role trusts the following services to assume the role:

  • Amazon Backup

The role permissions policy allows Amazon Backup to complete the following actions on the specified resources:

  • Action: list, read, and write on all resources Amazon Backup supports.

    See the policy AWSServiceRolePolicyForBackupRestoreTesting in the Amazon Identity and Access Management console for a list of specific permissions.

You must configure permissions to allow an IAM entity (such as a user, group, or role) to create, edit, or delete a service-linked role. For more information, see Service-Linked Role Permissions in the IAM User Guide.

Creating a service-linked role for Amazon Backup

You don't need to manually create a service-linked role. When you conduct restore testing in the Amazon Web Services Management Console, the Amazon CLI, or the Amazon API, Amazon Backup creates the service-linked role for you.

Important

This service-linked role can appear in your account if you completed an action in another service that uses the features supported by this role. To learn more, see A New Role Appeared in My IAM Account.

If you delete this service-linked role, and then need to create it again, you can use the same process to recreate the role in your account. When you conduct restore testing, Amazon Backup creates the service-linked role for you again.

Editing a service-linked role for Amazon Backup

Amazon Backup does not allow you to edit the AWSServiceRolePolicyForBackupRestoreTesting service-linked role. After you create a service-linked role, you cannot change the name of the role because various entities might reference the role. However, you can edit the description of the role using IAM. For more information, see Editing a Service-Linked Role in the IAM User Guide.

Deleting a service-linked role for Amazon Backup

If you no longer need to use a feature or service that requires a service-linked role, we recommend that you delete that role. That way you don’t have an unused entity that is not actively monitored or maintained. However, you must clean up your service-linked role before you can manually delete it.

Cleaning up a service-linked role

Before you can use IAM to delete a service-linked role, you must first delete any resources used by the role. You must delete all restore testing plans.

Note

If the Amazon Backup service is using the role when you try to delete the resources, then the deletion might fail. If that happens, wait for a few minutes, then try the operation again.
