In this paper we are going to reinforce Business Benefits of Cloud Computing, concentrating in backup technology referring to live migration technology. We have compare the time of live migration during a backup transition by using different hypervisors such as: ESX-I, XEN, OpenVZ and Hyper-V on a Cloud, which means that different Data Storage in different locations. Also we have improve the performance of live migration on such Hypervisors by implemented a program code in C called C_Software. It is implemented in User Space and it is part of each operating system which setup over those hypervisor. This means that it is independent from the type of Hypervisor. We are focused on Cloud Technology. From those experiments we can check that live migration is reduced in all Hypervisors mostly in XEN.
