How Restore to Amazon EC2 Works

The workflow of the restore process depends on the location of machine backups:

Restore from Repositories in Amazon S3

To restore a machine from backups located in external repositories or object storage repositories, Veeam Backup & Replication requires a proxy appliance. A proxy appliance is an auxiliary Linux-based instance. During the restore process, Veeam Backup & Replication uses the proxy appliance to upload disks of a backed up machine to AWS.

The restore process includes the following steps:

  1. Veeam Backup & Replication creates a proxy appliance in Amazon EC2.

During the restore process, the Veeam backup server communicates with the proxy appliance over the SSH protocol. A network redirector routes requests between Veeam Backup & Replication components and the proxy appliance.

  1. Veeam Backup & Replication hot-adds disks of the backed up machine to the proxy appliance.
  2. Veeam Backup & Replication creates a target instance in Amazon EC2.
  3. Veeam Backup & Replication removes machine disks from the proxy appliance and attaches them to the target instance.
  4. When the restore process is complete, Veeam Backup & Replication removes the proxy appliance from Amazon EC2.

Restore from Backup Repositories

To restore a machine from backups located in backup repositories, Veeam Backup & Replication performs the following steps:

  1. Veeam Backup & Replication uploads disks of a backed up machine to Amazon S3:
  1. Veeam Backup & Replication creates a target instance in Amazon EC2.
  2. Veeam Backup & Replication uses AWS CLI to import disk data from Amazon S3 to the target instance.

As part of the import process, AWS installs the needed storage and network drivers and services to make the restored machine accessible in Amazon EC2.

  1. [For Microsoft Windows machines] AWS installs or updates the Microsoft software licenses if you selected to obtain licenses from Amazon AWS.
