Hi,

We have implement this kind of solution with VNX5500 and DPM2012 RC.

And we run into a LOT of problems !

Here is first what you need in order to start your configuration:

The EMC Hardware provider : se7310-WINDOWS-x64-VSS.exe

The Unisphere CLI :NaviCLI-Win-32-x86-en_US-7.31.30.0.90-1.exe

Have the local protection license/Snapview Snapshot license for VNX

Create a RLP for your SNAP Space

Best Practice:

If Boot On San do NOT install the EMC Hardware Provider on C:

Create your RLP in dedicated disk

Do not install Powerpath fot this kind of configuration

Now useful document :

Home > Support > Technical Documentation and Advisories > Software ~ T-Z ~ Documentation > VSS Provider

Primus emc107717 and emc202636 for RLP

Now just a resume of different kind of error we encounter :

ou have also some registry key in order to tune your DPM server.

One of the most important one is the MaxAllowedParallelBackups which ios set to 3 by default starting DPM2010.
