In case of a disaster, you can restore corrupted EC2 instance volumes from a cloud-native snapshot or image-level backup. You can restore volumes to the original location or new location. When restoring to a new location, you can specify an AWS region, Availability Zone and other settings for restored volumes.
Veeam Backup for AWS does not attach restored volumes to EC2 instances — restored volumes are placed as standalone EBS volumes to the specified location.
How Volume-Level Restore Works
To restore EC2 instance volumes from cloud-native snapshots, Veeam Backup for AWS uses native AWS capabilities.
To restore EC2 instance volumes from image-level backups, Veeam Backup for AWS completes the following steps:
- Launches a worker instance in the AWS region where the restored 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 from the worker instance and transfers them to the target location:
- [For restore to the original location] Veeam Backup for AWS places the restored volumes as standalone EBS volumes to the original AWS region and Availability Zone.
- [For restore to a new location] Veeam Backup for AWS places the restored volumes as standalone EBS volumes to a specified AWS region.
- After the restore process is complete, Veeam Backup for AWS removes the worker instance from Amazon EC2.
