Secondary DPM Configuration

Hello All,

I am currently trying to configure a secondary DPM (both are 2012) to protect our primary server.

I am not receiving any errors but am not sure what configuration decisions to make.

Currently our Primary DPM is configured to protect itself. With the addition of a Secondary DPM, should I stop that?

When I attempt to protect the PDPM's C: from SDPM, It discovers the mount points for all of the replicas protected by PDPM, and asks to add these, should I?

After passing those messages, I am advised that the source (C:) cannot be protected because it is protected on the primary server.

my PDPM currently protects its own C: and system state.

Should I unprotect C: on the primary so I can do it from the Secondary, and do I need to add those mount points?

I have been unable to find a good configuration guide online, other than paraphrasing of  "protect the bits you want", which is not technical enough!

Thanks.
