About Hyper-V pass-through disks with NetBackup
This topic describes how to use NetBackup to back up Hyper-V pass-through disks. Hyper-V pass-through configuration allows a virtual machine to directly access physical disks. With pass-through access, a virtual machine can use large storage devices such as disk arrays. Access to a pass-through disk is faster than to a fully virtualized disk (vhd or vhdx file). A pass-through disk can be locally attached to the Hyper-V server or configured on a Fibre Channel SAN.
For assistance in setting up pass-through devices, refer to your Microsoft documentation.
The devices that NetBackup supports for pass-through are the same as for a physical (non-hypervisor) environment: the device vendor however must support the device in a virtual environment.
Note:
The NetBackup for Hyper-V feature and Hyper-V snapshot method (as described in other chapters of this guide) do not back up pass-through disks.
