Published: January 31, 2017

Updated: July 18, 2017

Applies To: System Center 2012 R2 Data Protection Manager

Keep these requirements and considerations in mind when you deploy System Center 2012 R2 Data Protection Manager (DPM).

If you’re evaluating your environment, see System Requirements for System Center 2012 R2

First things first

Decide how you want to deploy DPM:

  • As a physical standalone server—You can deploy DPM as a physical standalone server to backup on-premises data. Note that physical DPM servers can’t be deployed in a cluster, but you can manage multiple physical servers from a single console by installing Central Console on System Center Operations Manager.

  • As a Hyper-V virtual machine—You can run DPM as a virtual machine hosted on an on-premises Hyper-V host server, to back up on-premises data. For a list of considerations in this environment see Install DPM as a virtual machine on an on-premises Hyper-V server.

  • As a Windows virtual machine in VMWare—From DPM 2012 R2 with Update 5 onwards You can deploy DPM to provide protection for Microsoft workloads running on Windows virtual machines in VMWare. In this scenario DPM can be deployed as a physical standalone server, as a Hyper-V virtual machine, or as a Windows virtual machine in VMWare.

  • As an Azure virtual machine—From DPM 2012 R2 Update 3 onwards you can run DPM as a virtual machine in Azure to back up cloud workloads running as Azure virtual machines. For information about this deployment see Install DPM as an Azure virtual machine.

In all deployments you’ll need the following:

  • Instance of SQL Server installed and running for the DPM database. The instance can be collocated on the DPM server or remote.

  • Disk to be used as dedicated space for DPM data storage.

  • DPM protection agent installed on computers and servers you want to protect using DPM.

SQL Server database

DPM uses SQL Server as a database to store backup information for workloads, servers, and computers it protects.

Requirement Details
Version SQL Server 2014 with all service packs and updates - Standard or Enterprise 64-bit (from DPM 2012 R2 with Update Rollup 6 onwards)
Note: The DPM 2012 R2 Setup program does not support SQL Server 2014 for hosting the DPM database. Therefore, we don't recommend upgrading SQL Server 2012 to SQL Server 2014 after you install DPM 2012 R2.

SQL Server 2012 with all service packs and updates - Standard or Enterprise 64-bit

SQL Server 2008 R2 with all service packs and updates - Standard or Enterprise 64-bit
RAM 4 GB minimum, 8 GB recommended
Disk 1 GB minimum, 3 GB recommended
Required features Database Engine Services, Reporting Services
Collations SQL_Latin1_General_CP1_CI_AS
Dynamic ports Supported
AlwaysOn Not supported
Installation Install SQL Server on a remote server, or on the DPM server. It must be installed and running before you install DPM.
Remote installation - Install in the same domain and time zone as the DPM server.
- Installing SQL Server on a domain controller isn’t supported for DPM.
- Read about Setting up a remote SQL Server instance.
- If you’re deploying DPM as an Azure virtual machine you can specify an Azure virtual machine running SQL Server as a remote SQL Server instance. You can’t use an on-premises SQL Server, and using an Azure SQL Database isn’t currently supported.
Clustered SQL Server Supported

DPM server

Requirement Details
Hardware See Hardware.
Software Windows Server 2012 R2, Datacenter and Standard editions

Windows Server 2012, Datacenter and Standard editions

Windows Server 2008 R2 with SP1, Standard and Enterprise editions
Installation prerequisites Microsoft .NET Framework 4.0

Windows Installer 4.5 or later versions

Microsoft Visual C++ 2008 Redistributable

Windows PowerShell 3.0

Windows Single Instance Store (SIS)

Microsoft Application Error Reporting

Setup automatically installs these if they aren’t already installed.
Limitations You can install DPM on the operating system volume or on a different volume.

DPM 2012 UR11 is not supported on Windows Server 2008 R2.

VHDX are not supported on Windows Server 2008 R2.

VMware protection fails for DPM installed on Windows Server 2008 R2.

 DPM is designed to run on a dedicated, single-purpose server. Don’t install DPM on:

- A server running the Application Server role
- An Operations Manager Management server
- A server running Exchange
- A server running on a cluster node

DPM isn’t supported on the Turkish language version of any of the supported Windows Server versions.

Disks and storage

Requirement Minimum Recommended
Disk DPM requires:

- Disk for DPM installation—system files, installation files, prerequisite software, database files
- Disk dedicated to the storage pool
DPM installation DPM installation location: 3 GB

Database files drive: 900 MB

System drive: 1 GB

The system drive disk space is required if SQL Server is installed on the DPM server. If SQL Server is remote, you’ll need considerably less disk space for the system drive.		 On each protected volume you’ll need a minimum of 300 MB of free space for the change journal. In addition you’ll need space because DPM copies the file catalog to a temporary DPM installation location for archiving. We recommend that the DPM installation volume has 2–3 GB of free space.
Disk for storage pool 1.5 times the size of the protected data 2-3 times the size of the protected data
Logical unit number (LUN) Maximum of 17 TB for GUID partition table (GPT) dynamic disks

2 TB for master boot record (MBR) disks

Requirements are based on the maximum size of the disk that appears in the operating system.
Limitations DPM storage pools must be dynamic.

You can’t install DPM on the disk used for the storage pool.

You can attach or associate custom volumes with protected data sources. Custom volumes can be on basic or dynamic disks but you can’t manage the space on these volumes in the DPM Administrator console.

You can back up to tape with iSCSI attached tape libraries. We recommend a separate adapter for that connection. If you’re running DPM 2012 R2 with Update Rollup 3 or later you can also use virtual tape libraries with a virtual fibre channel adapter. For more information see Compatible tape libraries.
Virtualized DPM When DPM is running on a virtual machine it can use this storage:

- .VHD disk that meet the configuration requirements listed in Installing DPM in a virtual environment.
- Passthrough disk with host direct attached storage (DAS)
- Pass-through iSCSI LUN attached to a host.
- Passthrough Fibre Channel LUN attached to a host.
- iSCSI target LUN connected directly to the DPM virtual machine.
- Fibre Channel LUN connected to the DPM virtual machine using a Windows Server 2012 Virtual Fiber Channel (VFC) controller.

Protected workloads

Requirement Details
Protected workload size limits DPM can protect up to 600 volumes. 300 replica volumes and 300 recovery point volumes

At the maximum size protected sources are typically spread across approximately 75 servers and 150 client computers.

To protect this maximum size, DPM needs 120 TB per DPM server, with 80 TB replica space with a maximum recovery point size of 40 TB.
.NET framework All protected computers need at least .NET Framework 4.0 installed before you install the DPM protection agent.
Protected workloads Review the DPM protection support matrix for an up-to-date list of protected workloads.
Prerequisites DPM protection agent must be installed on protected computers. For more information, see Set up the protection agent.

Protected volumes must be at least 1 GB in size with NTFS formatting.

Server operating systems protected by DPM must be 64-bit.

Networking

Requirement Details
Domain The DPM server should be in a Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, Windows Server 2008, or Windows Server 2003 Active Directory domain.
Domain trust DPM supports data protection across forests as long as you establish a forest-level two-way trust between the separate forests.

 DPM can protect servers and workstations across domains within a forest that has a two-way trust relationship with the DPM server domain. If there’s no two-way trust DPM can provide protection for computers in workgroups or untrusted domains. For more information see Back up and restore workloads in workgroups and untrusted domains.
Network configuration If you’re protecting data over a wide area network (WAN), you’ll need a minimum bandwidth of 512 kilobits per second (Kbps).

 DPM doesn’t support disjointed namespaces.

Remote management

Requirement Details
Central Console Use the Central Console to administer multiple DPM servers from a single location.

Install it on a server running System Center 2012 Operations Manager. You’ll also need to install the Operations Management agent on the DPM server. See Install Central Console.
DPM Management Shell Install the DPM Management Shell on a client computer to directly manage one or more DPM servers using Windows PowerShell. Install it from DPM Setup.

The DPM Management Shell can be installed on computers running Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows 7, Windows 8, Windows 8.1. The computer must be running at least Net Framework 4.0.
Remote Desktop Connection Set up a Remote Desktop Connection to manage a single DPM server.

The DPM Administrator console can’t be installed on a remote computer.

The DPM Management Shell can be installed on computers running Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows 7, Windows 8, Windows 8.1. The computer must be running at least Net Framework 4.0.
