In case of a disaster, you can restore corrupted EBS volumes of EC2 instances from a cloud-native snapshot, snapshot replica or image-level backup. You can restore EBS volumes to the original location or new location. When you perform restore to a new location, you can specify the target AWS region, Availability Zone and other settings for restored EBS volumes.
Veeam Backup for AWS does not attach restored EBS volumes to EC2 instances. Restored EBS volumes are placed to the specified location as standalone EBS volumes.
How Volume-Level Restore Works
To restore EBS volumes from cloud-native snapshots and snapshot replicas, Veeam Backup for AWS uses native AWS capabilities.
To restore EBS volumes from image-level backups, Veeam Backup for AWS performs the following steps:
- Launches a worker instance in the AWS region where the restored EBS volumes will reside.
- Creates empty EBS volumes and attaches them to the worker instance.
The number of empty EBS volumes equals the number of volumes you selected to restore.
- Restores backed-up data to the empty EBS volumes on the worker instance.
- Detaches EBS volumes with restored data from the worker instance.
- After the restore process is complete, Veeam Backup for AWS removes the worker instance from Amazon EC2.
