Hello.
At location 1 I have two seperate domains, both being backed up by their own DPM 2007 server.
Now i need an external backup of those DPM servers at location 2.
Is is possible to set up one DPM 2007 server at location 2 , and use it to replicate data from both DPM servers at location 1?
Or would i have to setup two virtual servers with DPM at location 2, and replicate separately?

DPM's secondary protection (replication) is essentially turning on the DPM agent on each primary DPM server, and treating them like clients.  If the two DPM servers are members of domains that are in the same forest, and you establish trusts, your should be fine.

Thank you for your answer.

I should have made this clear. But the two DPM servers at location 1 are not in the same forrest.

In that case i assume the only option is to setup two virtual DPM servers at location two, and connect each of them to each DPM server at location 1?

Yes, that's the only option - no cross-forest support in DPM 2007.

If your virtualization platform is Hyper-V, virtualized DPM is supported under certain circumstances:

http://support.microsoft.com/kb/957006/
"Microsoft System Center Data Protection Manager  

Microsoft Systems Center Data Protection Manager 2007 is supported when it is  running inside a virtual machine as long as the DPM storage pool disks are made  available directly to the DPM virtual machine as one of the following:
Pass-through disks
iSCSI target disks
FC SAN target disks
You can also perform backups for the virtual  machines by either using a DPM agent that is installed on the host computer or  by installing the DPM agent into the virtual machine directly. "


Vendors like VMware participate in SVVP, which as far as I can tell validates MS operating systems running on 3rd party virtualization platforms, but I don't see specific references to DPM 2007, so some additional legwork is probably required to qualify say DPM 2007 running on ESX 3.5 for example.

Hope this helps

Wait, I stand corrected.  DPM 2007 SP1 adds cross-forest support assuming proper trust relationships:

If for some reason you still decide to virtualize, the SP also adds support for esx 3.5.
