Performing EC2 Backup

One backup policy can be used to process one or more instances either within one AWS account or within an entire AWS Organization. The scope of data that you can protect in an AWS account is limited by permissions of an IAM role that is specified in the backup policy settings, whereas the scope of data that you can protect in an AWS Organization is limited by permissions of an IAM role that is specified in the organization settings.

Before you create an EC2 backup policy, check the following prerequisites:

• If you plan to create image-level backups of EC2 instances, backup infrastructure components that will take part in the backup process must be added to the backup infrastructure and configured properly. These include backup repositories and worker instances.
• If you plan to receive email notifications on backup policy results, configure email notification settings first. For more information, see Configuring Global Notification Settings.
• If you plan to create transactionally consistent backups of EC2 instances, check the requirements for application-aware processing and guest scripting.

To schedule data protection tasks to run automatically, create backup policies. For each protected EC2 instance, you can also take cloud-native snapshots manually when needed.
