Managing Backup Repositories
Veeam Backup for AWS uses Amazon S3 buckets as target locations for EC2 instance image-level backups, additional copies of Amazon VPC backups, indexes of EFS file systems and Veeam Backup for AWS configuration backups. To instruct Veeam Backup for AWS to store backups in a specific Amazon S3 bucket, configure a backup repository. For more details, see Adding Backup Repositories.
To communicate with the backup repository, Veeam Backup for AWS uses the Veeam Data Mover — the service running on a worker instance that is responsible for data processing and transfer. When a backup policy addresses the backup repository, the Veeam Data Mover establishes a connection with the repository enabling data transfer. To let the Veeam Data Mover access the target Amazon S3 bucket, Veeam Backup for AWS uses permissions of an IAM role specified in backup repository settings.
