Veeam Backup for AWS performs RDS backup in the following way:
- Veeam Backup for AWS creates a storage volume snapshot of the processed DB instance (that is, a DB snapshot) or of the processed Aurora DB cluster (that is, a DB cluster snapshot).
The snapshot is assigned AWS tags upon creation. Keys and values of AWS tags contain encrypted metadata that helps Veeam Backup for AWS identify the related snapshot. For the Aurora DB cluster metadata saved in AWS tags also contains information on every DB instance launched in the cluster.
- If you enable snapshot replication for the backup policy, Veeam Backup for AWS copies the snapshot to the target AWS Region and AWS account specified in the backup policy settings.
Snapshot replication is not supported for Aurora multi-master clusters.
