Amazon EBS Direct API Restore Process for Amazon EC2 Instances Including Amazon VPC Resources

When Amazon VPC protection is enabled, the EBS direct API restore process includes the following stages:

1. Create empty snapshots in the destination using the StartSnapshot API.

2. Write data by running the PutSnapshotBlock API.

3. Complete the snapshots using the CompleteSnapshot API.

4. Create volumes from snapshots.

5. Check and validate the network entities such as VPC, subnet, security groups, and NICs. If any entities are deleted, re-create them.

6. Attach the volumes:

   • If the instance exists, attach the new volumes to the instance.

   • If the restore is to a new instance, create a new instance with the restored network configuration and attach the restored EBS volumes.

7. Delete the snapshots.
