DPM 2012 backup of SQL Server VMs

I've been unable to find anything on this and would like to know what the best practice DPM configuration is for using DPM to backup Virtual machines running SQL Server.

My hunch is that it's BMR + SQL Server + volume data in the VM directly rather than using Hyper-V 'Backup Using Child Partition Snapshot', I'm not sure what DPM would do with the SQL Server databases in the latter scenario.

Is there a way to backup just the SQL Server databases using the SQL directly in VM agent and just the rest with the Child Partition Snapshot at the Hyper-V host level?

(In case it matters versions are: SCDPM 2012, SQL Server 2008 R2, Windows Server 2008 R2)

Thanks in advance.
