I am trying the Alibaba Cloud, ECS instances and after doing some configuration I would like to persist that so that if I want to rollback the Instance after certain period I can start from the last checkpoint. What I want to understand is if Taking a SnapShot/Image on Free trial would cost me money ? or in other words if I create an image or snapshot would that be chargeable, if yes then how much would it cost to me for each snap shot or image?
Best Regards
