Snapshots can be used to create a backup of critical workloads, such as a large database or a file system that spans across multiple EBS volumes. Multi-volume snapshots allow you to take exact point-in-time, data coordinated, and crash-consistent snapshots across multiple EBS volumes attached to an EC2 instance.

How does EC2 work with EC2 instances?

Instances communicate with the Run Command API to retrieve commands to execute and return results, and with the EC2 API to get volume attachment information and create EBS snapshots. To grant permission to call the APIs, I launch the instances with an IAM role for EC2 instances.

What does run command do in AWS EC2?
