Protecting virtual machine disks by setting the disk protection
Select the virtual machine (VM) disks to include in virtual machine backups.
About this task
VM disks are identified by the disk number. For example, in most cases, disk 1 is the system disk.
Complete this procedure if you want to change the default backup behavior, which includes all VM disks in a backup operation. You can also change a non-default behavior that is inherited from a parent object.
