Veeam Backup for AWS does not install agent software within instances to retrieve data, instead, it uses native AWS capabilities to backup resource data. During every backup session, Veeam Backup for AWS creates a cloud-native snapshot (for an EC2 instance and RDS resource) or a cloud-native backup (for an EFS file system) for each AWS resource added to a backup policy. The cloud-native snapshot is further used to create a snapshot replica (for an EC2 instance and RDS resource) in another AWS Region or another AWS account and an image-level backup (only for an EC2 instance), the cloud-native backup (for an EFS file system) is further used to create a backup copy in another AWS Region. To protect Amazon VPC configurations, Veeam Backup for AWS retrieves configuration data through API and saves this data to the configuration database. You can also instruct Veeam Backup for AWS to store copies of VPC configuration backups in a backup repository.
