Hey guys,

I evaluate the free edition of Vembu and try to backup a CentOS VM running on Hyper-V. The backup always fails with the error:

"Snapshot initialization failed ,as volume could not be added to Snapshot Set"

If I make a manual checkpoint in Hyper-V manager I can create it successfully, but not with Vembu. Is there something that needs to be installed on the CentOS VM? The HV integration services are installed:
