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.
- If you plan to receive email notifications on backup policy results, configure SMTP server settings first. For details, see Configuring Global Email Notification Settings.
- If you plan to create transactionally consistent backups of Windows EC2 instances, check these requirements.
