How to duplicate AWS EC2 instance without any downtime?

I have an AWS EC2 instance which I want to use it for testing. I create an AMI, but the machine goes down after a while.

How do I duplicate the EC2? Is it possible?

Technically it is not possible, because the machine actually reboots when you create an AMI. The only thing you could do is copy the disk to another disk which is also very difficult to do.

AWS EC2 powers down the instance, take images, creates and registers the AMI and then reboots the instance. So there would definitely be some downtime.
