Protecting Components in a Virtualized Environment
Source: Hewlett-Packard (HP)
Protecting data in a server virtualized environment adds another layer of challenge and complexity for the backup administrator, thus, leaving gaps in a total protection strategy. Protection is now required at two levels, first the Virtual Machine (VM) and second, the application data residing inside the virtual machine. The most widely used backup method employed in virtualized environments is placing an online backup agent inside the virtual machine. This is the standard backup method used in the physical world today. The online agent is "application aware" communicating to the application that a backup or restore is occurring.
