Hello,

I am having some difficulties backing up a two node Hyper-V cluster running on Win 2012.

NMM version is  2.4.1

Server version is 8.0.3.0 build 329 (both support 2012 I believe, as per compatibility matrix)

Backup command :

nsrsnap_vss_save.exe -s svhostname

or

nsrsnap_vss_save.exe

Snapsots enabled:

Rollover ALL

1 per day, retain1

Client direct is disabled. I attempted to back up a single VM off a physical node and job fails with message below :

APPLICATIONS:\Microsoft Hyper-V\CAROM2: NSRSNAPCK::success

Additionally, when running nsrsnap_vss_save -s -? the application crashes on the Hyper-V node side. Event Viewer error output is below :

Has anyone seen this kind of error before ?

Thanks,
