Backup - Disk Dynamic Hyper-V Windows 2012 via Client

Good morning Mariane, can you help me?

I'm having trouble backing up a client that has dinamic disk.

My environment:

Master: 7.6.02 OS: Linux red. hat 6 - Veritas Cluster
Medias Servers: 07/06/02 - Linux red. hat 6
Client Windows 2003 (Virtual Machine) - Hyper-V Cluster 6.3.9 ....

I run the backup via client installed on this virtual machine and returns error 156.
The netbackup supports not do the same with backup client installed to dinamic disk ???

Thank you very much
