Before you create a backup policy, check the following prerequisites:
- Backup infrastructure components that will take part in the backup process must be added to the backup infrastructure and properly configured. These include S3 repositories and worker instances.
- Make sure you added an IAM role that has permissions on EC2 instances you plan to back up. For information on how to add IAM roles, see Adding IAM Roles.
- If you plan to receive notifications on the backup policy results, make sure you configured SMTP server settings. For details, see Configuring Global Email Notification Settings.
