How to backup Clustered Shared Volumes (CSVs) of Hyper-V in NetBackup 8.1.2?

Jess01 - backing-up the VHD(X) files direct from CSV is not really how you take a backup of a VM in Hyper-V - maybe you could if the VM was shutdown, but I have no idea whether that would result in a restorable/recoverable entity.  Likewise no-one backs-up VMDK direct from VMFS data-stores.

Plus you have a live, open, writeable database to deal with.

Here are some options:

1) install NetBackup Client on all Hyper-V hosts in the Hyper-V cluster - then shutdown SAP database, shutdown VM - take a NetBackup Hyper-V style (whole VM) backup of the VM (which essentially achieves what you said in your opening post) - this assumes that the SAP database lives in non-sparse files on NTFS volumes and is not abstracted in any mix of proprietary partition/volume-manager/file-system.

2) install NetBackup Client on all Hyper-V hosts in the Hyper-V cluster - then shutdown SAP database, leave VM up - take a NetBackup Hyper-V style (whole VM) backup of the VM whilst it is up and online (this is pretty much the same as option 1) - same assumptions as option 1.

3) install NetBackup Client inside the VM (i.e. no need to install NetBackup Client on any Hyper-V host) - configure NetBackup Client for SAP and take a SAP database backup - and also take a NetBackup BMR aware backup of the OS elements of the guest VM - assuming interop of NetBackup Client + NetBackup BMR Client + OS family + OS version + LUN format (GPT/MBR) + partition layout + volume manager + file-system type + file-system version + file-system size - all these elements have to be supported interop together to achieve a valid NetBackup BMR Client backup.
