Step 4. Specify IAM Role
[This step applies only if you have added multiple IAM roles to the Veeam Backup for AWS appliance]
At the IAM Identity step of the wizard, select an IAM role whose permissions will be used to create the repository and to access the target Amazon S3 bucket. For more information on the required permissions that must be assigned to the IAM role, see the Veeam Backup for AWS User Guide, section Repository IAM Role Permissions.
For an IAM role to be displayed in the IAM role drop-down list, it must be added to the Veeam Backup for AWS appliance as described in the Veeam Backup for AWS User Guide, section Adding IAM Roles, and must belong to the same AWS account to which the IAM user specified at step 3 of the wizard belongs.
