DP 7.03 vs. HyperV 2012 R2, offline backup

Hello,

have anybody experience with backup MS HyperV 2012 R2 using HP Dataprotector (7.01 - 7.03)?

We have two HyperV farms (3nodes for 2012, 2nodes for 2012 R2).
Farm 2012 is backuped by HPDP using MS Volume Shadow Copy Writers integration. Each VM can be backuped ONLINE.

We would like use same method for 2012 R2 farm, but each VM is backuped OFFLINE (enter to save mode, creating snapshot, enter to running mode).

Is it possible to backup VM on HyperV 2012 R2 ONLINE?

OS on every VM is from Microsoft.

Thank you for your help.
