Step 3. Select IAM Role to Access S3 Resources
At the Account step of the wizard, select an IAM role whose permissions Veeam Backup for AWS will use to access the target Amazon S3 bucket.
For an IAM role to be displayed in the IAM Role list, it must be added to Veeam Backup for AWS as described in Adding IAM Roles. If you have not added the necessary IAM role to Veeam Backup for AWS beforehand, you can do it without closing the Add Repository wizard. To add an IAM role, click Add and complete the Add Account wizard.
