All EBS volumes can be copied by creating a snapshot. Existing snapshots can be used to generate other volumes that can be shared and/or attached to other instances or converted to images from which AMIs can be made. You can also generate an AMI image directly from a running instance‐attached EBS volume—although, to be sure no data is lost, you should shut down the instance first.

EBS volumes can be encrypted to protect their data while at rest or as it's sent back and forth to the EC2 host instance. EBS can manage the encryption keys automatically behind the scenes or use keys that you provide through the AWS Key Management Service (KMS).

Exercise 2.4 will walk you through launching a new instance based on an existing snapshot image.
