Master Server - Windows 2008 R2
Media Servers Windows 2008R2 & Windows Server 2012
Netbackup Version - 7.6.1.1
Policy Config - Hyper-V using Provider auto\system advance attributes
Hyper-V Servers - Windows 2008 R2 standalone and clustered servers (Same issue on both)
I am trying to configure online backups using the hyper-v agent on 2008 R2 host with 2012 & 2012 R2 quest. Here is the error message:

These servers will backup fine when the option is selected for "enable offline backup for non-VSS VMs". I would really like to leave these server online.
Any help would be great!

This looks like an issue with VSS.
As per this TN: http://www.symantec.com/docs/HOWTO70869 this option is intended for guest operating systems that do not support VSS.
Have a look at suggestions in this TN: http://www.symantec.com/docs/HOWTO70792
such as:
The Hyper-V integration component is absent.
The VSS framework in the virtual machine does not work properly
... and more...

Have you checked that the hyper-v integration service is installed on the VMs ?
As your hypervisor OS is a lower version than the VM's OS, have you checked that online backup is supported by microsoft for this configuration ?
Also check the event logs on the VMs and Hyper-V host for entries by VSS and volsnap and other errors at time of the problem
