Virtual server backup is primarily an enterprise backup procedure performed on all virtual servers. It is like typical server backup except that in this case, the server is virtualized. Typically, most server virtualization hypervisors have a built-in component for data backup procedures or a third-party application is installed on each virtual server instance. The virtual server hypervisor or the external backup application connects with a local or remote backup storage device to initiate and execute the backup process. Depending on the capabilities of backup software, a virtual server can be backed up as an entire virtual machine image/snapshot or as an incremental file level backup.
