Performing Volume-Level Restore
In case a disaster strikes, you can restore corrupted EBS volumes of an EC2 instance from a cloud-native snapshot, snapshot replica or image-level backup. Veeam Backup for AWS allows you to restore EBS volumes to the original location or to a new location.
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:
- [This step applies only if you perform restore from an archived backup] Retrieves data from the archived restore point.
- 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.
- Removes the worker instance from Amazon EC2.
Veeam Backup for AWS does not attach restored EBS volumes to any EC2 instances — the volumes are placed to the specified location as standalone EBS volumes.
To restore an EBS volume from a backup that is stored in the archive backup repository, the archived data must be retrieved first. You can retrieve the archived data manually before you begin the restore operation, or launch data retrieval from the Restore wizard. For more information on data retrieval, see Retrieving Data From Archive.
If you plan to restore EBS volumes to an AWS Outpost, check the following prerequisites:
- An IAM role you plan to specify for the restore operation must have the following permissions: outposts:ListOutposts, outposts:GetOutpostInstanceTypes. To grant the necessary permissions for the IAM role, use the AWS Management Console.
- If the Outpost subnet is specified in the worker configuration settings, restore of EBS volumes to an AWS Region to which the AWS Outpost is connected may fail. The issue occurs if the default worker instance type is not supported for the AWS Outpost. In this case, change the default worker profiles as described in section Managing Worker Profiles.
