Before you deploy DPM to protect client computer data verify the deployment prerequisites:

  • Read about the supported clients in DPM protection support matrix.

  • Review the release notes and The Supported and unsupported scenarios in DPM for any client protection issues.

  • Ensure that client computers you want to protect are in the DPM server domain, or in a domain with a two-way trust relationship with the domain in which the DPM server is located.

  • If Windows Firewall is configured on the client computer, the DPM protection agent installation configures the necessary firewall exceptions. If you need to reset the firewall, you can reconfigure it by running SetDpmServer.exe. If you are using a firewall other than Windows Firewall, ensure that the necessary ports for DPM are open.

  • DPM can perform backups of client computers connected over VPN. Internet connection speed must be a minimum of 1 Megabit per second (Mbps). To perform backups over VPN, you must enable the Internet Control Message Protocol (ICMP).

  • DPM can perform backups of client computers that are either physically or wirelessly connected to the LAN. For client computers that are continuously connected to the network, ensure that sufficient bandwidth is available for DPM. We recommend a minimum network bandwidth of 256 Kilobits per second (Kbps) for computers that are continuously connected to the network.

  • Each System Center 2012 – Data Protection Manager (DPM) server can protect up to 3000 client computers that are running either the 32-bit or 64-bit versions of supported operating systems.

  • If client data backup is slow you can tweak this registry setting: HKLM\Software\Microsoft\Microsoft Data Protection Manager\Agent\ClientProtection. Set the valkue WaitInMSPerRequestForClientRead to a lower value.

  • To scale up client performance you can tweak these registry keys:

    • Software\Microsoft\Microsoft Data Protection Manager\Configuration\DPMTaskController\MaxRunningTasksThreshold. Value: 9037ebb9-5c1b-4ab8-a446-052b13485f57
