Requirements for backing up Hyper-V pass-through disks
Note the following requirements:
Consult your Microsoft documentation for pass-through configuration requirements.
Consult your VSS provider documentation for snapshot preconfiguration requirements. For example, the disk array clones or mirrors must be synchronized with the disk array source device before the backup is started.
NetBackup may require certain OS and array configuration, depending on the guest OS and the array. For details, see the disk arrays chapter of the NetBackup Snapshot Client Administrator's Guide.
For backups using a VSS provider type of Hardware, pass-through disks should be added as SCSI disks.
NetBackup client software must be installed on the virtual machine.
To use Snapshot Client for local snapshot or alternate client backup, Snapshot Client must be licensed on the virtual machine.
For alternate client backup, the virtual machine and alternate client must be running the same operating system, volume manager, and file system. For each of these I/O system components, the alternate client must be at the same level as the primary client, or higher level.
For complete requirements on alternate client backup, refer to the Policy configuration chapter of the NetBackup Snapshot Client Administrator's Guide.
Note:
The requirements for the NetBackup for Hyper-V feature do not apply to backups of the disk arrays that are configured as pass-through disks. The NetBackup for Hyper-V feature (using the Hyper-V snapshot method as described in other parts of this guide) does not back up pass-through disks.
