Then add a Custom ICMP rule with Protocol as Echo Request. For source, add Anywhere so that you can ping from any machine you want. Check out this screenshot for a better understanding.
I ran a test that measures latency between EC2 instances in different regions. The table below shows the average time in milliseconds it took for an EC2 instance in region A to receive a ping response from an EC2 instance in region B. My sample size is 1,000 requests per each calculated value. Try to edit the 'Security group' of your aws ec2 instance by allowing the access or create a new one and add an instance. As everything is denied by default, security groups decide to make it available on the internet based on the service we need. inv_trick.yml uses host variables from the ec2_instances group defined in the inventory file and "forwards" them to the ec2 module. Both designs create a dynamic_group in the playbook from the ec2 results. The final play in the playbook then runs the ping task to demonstrate that tasks can be performed on the newly created dynamic_group.

This method of EC2 backup involves more steps than taking EBS snapshots.
