IT organizations are well-versed in protecting their physical infrastructure and data from interruptions. Most organizations employ some level of data protection to minimize downtime and data loss in the event of a disruption. Just as introducing multiple operating systems created complexity and challenges, as these organizations incorporate virtual servers in their environment; new challenges are developing for protecting the mix as a whole. As deployments of server virtualization proliferate and new server virtualization technology becomes available, the combination of new and incumbent vendors adds another dimension to the heterogeneity of the environment. Workloads running on different operating systems and on physical and virtual servers complicate operational and disaster recovery.
