The perominence of these virtual systems, that assume the major part of the workload is increasing day by day, making the systems the most critical part of the companies. Taking all these into consodiraiton, companies need a powerfull disaster recovery management to supply bussiness continutiy and to avoid data loss or lock of access in a possible disaster situtaion.
