In case of a disaster, you can restore an entire EC2 instance from a cloud-native snapshot or image-level backup. You can restore one or more EC2 instances at once, to the original location or new location. When restoring to a new location, you can specify an AWS region, VPC, instance type and so on.
How Entire EC2 Instance Restore Works
To restore EC2 instances from cloud-native snapshots, Veeam Backup for AWS uses native AWS capabilities.
To restore EC2 instances from image-level backups, Veeam Backup for AWS completes the following steps:
- Launches a worker instance in the AWS region where the target EC2 instance will reside.
- Creates empty EBS volumes and attaches them to the worker instance.
The number of empty EBS volumes equals the number of EBS volumes attached to the backed-up EC2 instance.
- Restores backed-up data to the empty EBS volumes on the worker instance.
- [For restore to a new location] Creates a target EC2 instance in the specified AWS region.
- Detaches EBS volumes from the worker instance and attaches them to the target EC2 instance.
- After the restore process is complete, Veeam Backup for AWS removes the worker instance from Amazon EC2.
