What is Data Protection Manager?

Microsoft System Center Data Protection Manager (DPM) 2010 is a member of the Microsoft System Center family of management products, designed to help IT professionals manage their Windows environment. DPM provides Windows backup and recovery—delivering seamless data protection for Microsoft application and file servers by using integrated disk and tape media. DPM performs replication, synchronization, and recovery point creation to provide reliable protection and rapid recovery of data for both system administrators and end-users.

For more information about DPM 2010, its features, and how it works, see Introducing Data Protection Manager 2010.

What's New in DPM 2010?

Some of the new features for DPM 2010 include:

• DPM 2010 automatically grows volumes as required.

• DPM 2010 allows you to shrink volumes so your space is used effectively.

• Support for system protection of Windows Server 2008 and Windows Server 2008 R2.

• Exchange Server 2010 databases now appear within the Database Availability Group (DAG) after creating a new protection group.

• Improved Windows SharePoint support for the following:

  • Restoring individual SharePoint list items.

  • Parallel backups of databases that are on the same instance of SQL Server 2005 in a SharePoint farm.

  • SharePoint list item search recovery. Note that you can now perform a search based on the title of the list item.

  • SharePoint tape backup.

    In DPM 2010, DPM takes the last valid backup at the database level, and then copies the backup to tape. This process creates a complete recovery point for the SharePoint farm. In previous releases, the latest farm level recovery point was backed up to tape, and might not have included all of the databases causing the copy-to-tape operation to be incomplete.

  • Recovery of items in a SharePoint farm using host-headers.

For a complete list of the new features for DPM 2010, see What's New in DPM 2010.

What languages does DPM 2010 support?

In addition to English, DPM 2010 supports Chinese Simplified, Chinese Traditional, French, German, Italian, Japanese, Korean, and Spanish, Portuguese (Brazilian) and Russian.

Back to Introduction

Does DPM 2010 support a tape-based backup and archive solution?

Yes. DPM provides tape-based and disk-based protection for your data, which can be deployed as follows:

• Disk-to-disk (D2D). A method of backup in which data from one computer is stored on the hard disk of another computer. You can use this method to back up your DPM server using your existing alternative tape product.

• Disk-to-tape (D2T). A traditional method of backing up data from one computer to a type of storage media, such as tape.

• Disk-to-disk-to-tape (D2D2T). This method combines D2D and D2T for extra protection. D2D2T provides the rapid recovery benefits of disk-based storage in the short term and archive storage for critical data using tape-based storage in the long term.

Back to Introduction

Does DPM support protection across forests?

DPM 2010 supports data protection across forests if a forest-level trust exists between the forests. To set up a forest-level trust relationship, both domains must be in Windows Server 2003, Windows Server 2008, or Windows Server 2008 R2 forest mode. Windows Server 2000 does not support forest-level trusts. For information about setting up a forest-level trust relationship, see Checklist: Creating Forest trust (https://go.microsoft.com/fwlink/?LinkId=136803), and Create a forest trust (https://go.microsoft.com/fwlink/?LinkId=136804).

What Exchange Server configurations does DPM 2010 support?

The following table lists the Exchange Server configurations that DPM 2007 supports.

Back to Introduction

Does DPM 2010 provide Windows PowerShell Integration?

DPM 2010 provides its own set of Windows PowerShell commands that can be used in addition to DPM Administrator Console to perform data protection management tasks. A DPM administrator can use DPM cmdlets to perform many of the administrative tasks that can be performed in the console. You access the DPM cmdlets through DPM Management Shell.

Back to Introduction

Can I manage my DPM servers remotely?

Yes. DPM Management Shell can be installed on computers other than the DPM server, enabling you to administer multiple DPM servers remotely. You can also install DPM Management Shell on desktop computers running Windows XP, Windows Vista, or Windows 7.

Back to Introduction

How do I determine how many DPM servers my organization will require?

There is no precise algorithm for determining the number of DPM servers you will need. The number of servers and the amount of data that a single DPM server can protect will vary based on the following factors:

• Change rate of the data sources to be protected

• The amount of space available in the storage pool

• How often the data will be synchronized

• Available bandwidth at each protected computer

• Aggregate bandwidth on the DPM server

For more information, in Planning a DPM 2010 Deployment, see Planning the DPM Server Configurations (https://go.microsoft.com/fwlink/?LinkId=179155).

Back to Introduction

How many snapshots can a DPM server retain?

A DPM server can store up to 9,000 disk-based snapshots, including those retained when you stop protection of a data source. The snapshot limit applies to express full backups and file recovery points, but not to incremental synchronizations.

DPM 2010 Licensing

What types of licensing does DPM have?

DPM has standard, enterprise, and client licenses. The standard license entitles you to protect volumes, shares, and folders, as well as computer system state. The enterprise license entitles you to protect application data, such as mailboxes and databases on an Exchange Server, in addition to files. On a server cluster, DPM installs an agent on each node of the cluster. A license is used for each server node. A client license entitles you to protect desktop and laptop computers running Windows XP, Windows Vista, or Windows 7.

For more information about which license types you need for the various types of data that DPM protects, see DPM Licensing.

Back to Introduction

Where can I purchase additional DPM 2010 licenses?

You can purchase additional DPM licenses through the Microsoft Partner Program (https://go.microsoft.com/fwlink/?LinkId=71663).

Back to Introduction

Installation and Setup

What are the system requirements for running DPM 2007?

DPM Server Software Requirements

The System Center Data Protection Manager (DPM) 2010 server requires a 64-bit version of a supported operating system and requires a supported 64-bit or 32-bit version of SQL Server 2008 SP1, Enterprise or Standard Edition, for the DPM database.

The DPM server must be installed on a computer that is running the 64-bit version of one of the following operating systems:

• Windows Server 2008 R2, Standard or Enterprise Edition

• Windows Server 2008, Standard or Enterprise Edition

For more information about installing DPM on one of the supported operating systems, including important updates that you must apply, see DPM Supported Operating Systems.

DPM Server Hardware Requirements

DPM is designed to run on a dedicated, single-purpose server. The DPM server should not be installed on any of the following:

• A computer on which the Application Server role is installed

• A computer that is a System Center Operations Manager management server

• A computer on which Exchange Server is running

• A computer that is a node of a cluster

For information about the minimum and recommended hardware requirements for the DPM server. For more information about planning DPM server configurations, see Hardware Requirements.

Network Requirements

The DPM server must be deployed within a Windows Server 2008 R2, Windows Server 2008, or Windows Server 2003 Active Directory domain. The domain controllers can be running Windows Server 2000, Windows Server 2003, or Windows Server 2003 R2 Server.

DPM 2010 supports protecting servers across domains; however, you must establish two-way trust relationship across the domains prior to protecting the computers.

The DPM server requires persistent connectivity with the servers and desktop computers that it protects.

For more information about the network requirements, see Network Requirements.

Back to Introduction

Can DPM be installed from a network share?

Yes. You can run DPM Setup from a network share by using a Universal Naming Convention (UNC) path. However, you cannot run DPM Setup by using a drive that maps to a network share.

If you experience errors when running DPM Setup from a network share by using a UNC path, follow these steps:

1. Exit DPM Setup.

2. Copy the DPM installation folder to a local folder on the DPM server.

3. Restart the DPM installation from the local installation folder.

Back to Introduction

Storage Pool Configuration

What types of storage can I use with DPM 2010?

DPM 2010 supports use of any of the following sources for server storage:

• Direct attached storage (DAS).

• Fibre Channel storage area network (SAN)

• Internet SCSI (iSCSI) storage device or SAN, providing that the iSCSI storage device has received Windows Hardware Certification.

What is a custom volume?

You can assign a custom volume to a protection group member, in place of the DPM storage pool. A custom volume is a volume that is not in the DPM storage pool and is specified to store the replica and recovery points for a protection group member.

Any volume that is attached to the DPM server can be selected as a custom volume, except the volume that contains the system and program files. To use custom volumes for a protection group member, two custom volumes must be available: one volume to store the replica and one volume to store the recovery points

When should I use custom volumes?

The DPM-managed storage pool is sufficient for most business needs; however, you might want a greater amount of control over storage for specific data sources. For example, you have critical data that you want to store using a high-performance logical unit number (LUN) on a storage area network.

Back to Introduction

Can I use mapped network drives?

No, you cannot add mapped drives to a storage pool.

Disaster Recovery

Can you use a DPM server to protect its databases?

Yes, a DPM server can protect its own databases by backing the databases up to tape. We recommend that you use a unique protection group to back up the DPM server databases, make at least two copies of the backup tapes, and then store each of the backup tapes in a different remote location. For more information, see "Preparing for Disaster Recovery" in Notfallwiederherstellung.

Back to Introduction

Can DPM 2010 protect system state?

Yes. DPM 2010 can protect the system state for any computer on which a DPM protection agent can be installed.

What system state components does DPM protect?

The following table shows the protected components for each system state that DPM backs up:
