Virtual Server Backup is the process of copying the data, application and operating system - stored on a virtual server - within a virtualized environment to guard against the data loss. Virtual server backup can be performed using conventional backup software. By the use of a server virtualization hypervisor, a virtual server backup is build.
Virtual server backup is mainly an enterprise backup process accomplished on all virtual servers. It is necessary that the backup software is installed on each virtual machine, and backup will usually run to any conventional backup target. Although, it is the simplest approach to virtual server backup, it may lead to resource issue. You may need some additional resources to perform a backup that may include the performance of the virtual machines on the physical server being backed up. Additionally, you’ll need a backup software license for each virtual machine that needs to be backed up.
