Shared VHDX and crash consistent-state backup

Hi ...

I'm A DBA, the Microsoft provide support for Shared VHDX in 2012. As you know we can run Windows Failover cluster on shared VHDX. Some backup software is taking backup of these VMs under some limitation like cannot use snapshots.

One of these limitation is using VAEEM. they backup VMs in crash-consistent state which mean simply an image can be compared to the state of a VM that has been manually reset. Unlike offline backup,  I don't know  if this is O.k with Microsoft SQL server backup
