Configurations for backing up pass-through disks
You can use either of the following NetBackup configurations to back up Hyper-V pass-through disks:
Without Snapshot Client.
Install a NetBackup client on the virtual machine. You can configure NetBackup to back up virtual machine data as if the client was installed on a physical host. Note that without Snapshot Client software on the virtual machine, the features of Snapshot Client are not available.
With Snapshot Client (explained in this appendix).
Install a NetBackup client on the virtual machine, as well as a license for Snapshot Client. Configure either a local snapshot backup or an alternate client backup.
To use a VSS hardware provider for the disk array, the off-host alternate client method is required.
