auto discovery

The daily process by which DPM automatically detects new or removed servers on the network and discovers changes to protected file servers, such as the addition, removal, or renaming of shares and volumes.

backup shadow copy

A shadow copy of a replica created by the DpmBackup command-line tool. In DPM, backup shadow copies are used to archive replicas to tape.

consistency check

The process by which DPM checks for and corrects inconsistencies between a protected volume and its replica. A consistency check is performed only when normal mechanisms for recording changes to protected volumes, and for applying those changes to replicas, have been interrupted.

data source

In DPM, a share, volume, folder, or file that is a member of a protection group.

Details pane

The lower left pane in DPM Administrator Console. The Details pane provides detailed information about an item selected in the Display pane.

A log that stores DPM alerts as Windows events so that the alerts can be displayed in Microsoft Operations Manager (MOM).

DPM database (DPMDB.mdf)

The SQL Server database that stores DPM settings and configuration information.

DPM File Agent

Software, installed on a file server, that records changes to protected data in a synchronization log, and transfers the log from the file server to the DPM server.

DPM File Agent service

The component of DPM that synchronizes replicas of protected volumes with the data sources. The DPM File Agent service receives changes to protected data from the file servers and applies the changes to the replicas on the DPM server.

DPM Management Pack

A licensed set of processing rules, filters, and alerts, which can be imported onto a MOM Management Server to enable an administrator to centrally monitor data protection, state, health, and performance of multiple DPM servers in Microsoft Operations Manager (MOM).

DPM service

The core component of DPM. The DPM service manages all core DPM operations, including replica creation, synchronization, and shadow copy creation.

DPM Writer service

A service that manages backup shadow copies of DPM replicas, and backups of the DPM and Report databases, for purposes of data archival. The DPM Writer service is invoked by the DpmBackup command-line tool.

DPMADSchemaExtension

A command-line tool that enables a schema administrator to configure Active Directory for the purpose of enabling end-user recovery.

DpmBackup

A command-line tool that enables an administrator to archive the contents of a DPM server by using tape backup software that is not specifically designed for use with DPM.

DPMDB.mdf

The file name of the DPM database, the SQL Server database that stores DPM settings and configuration information.

DPMDBReaders group

A group, created during DPM installation, that contains all accounts that have read-only access to the DPM database. The DPMReport account is a member of this group.

DpmPathMerge

A command-line tool that removes extraneous path information from data that has been restored to a DPM server from tape.

DPMReport account

The account that the Web and NT services of SQL Server Reporting Services use to access the DPM database. This account is created when an administrator configures DPM reporting.

DpmSync

A command-line tool that provides disaster recovery functionality for DPM. DpmSync restores the DPM database and the Report database, and synchronizes the DPM database with the state of the storage pool and the installed DPM File Agents.

end-user recovery

A feature that enables an end user to independently recover data by retrieving a shadow copy. This feature requires the shadow copy client software.

file agent

See definition for: DPM File Agent

FsPathMerge

A command-line tool that removes extraneous path information from data that has been restored to a protected file server from tape.

MICROSOFT$DPM$

The name that DPM Setup assigns to the SQL Server instance used by DPM.

MICROSOFT$DPM$Acct account

The low-privilege account under which DPM runs its SQL Server and SQL Agent services. This account is created during DPM installation.

Microsoft$DPMWriter$ account

The low-privilege account under which DPM runs the DPM Writer service. This account is created during DPM installation.

MSDPMTrustedMachines group

A group that contains the domain accounts for file servers that are authorized to communicate with the DPM server. DPM uses this group to ensure that only file servers that have the DPM File Agent installed from a specific DPM server can respond to calls from that server.

MSSQL$MICROSOFT$DPM$ service

See definition for: SQL Server service (MSSQL$MICROSOFT$DPM$)

network bandwidth usage throttling

A performance optimization in DPM that limits the percentage of network bandwidth that protection and recovery jobs can consume.

on-the-wire compression

A performance optimization in DPM that reduces the size of data transferred during replica creation and synchronization, thereby increasing the rate of data throughput without negatively affecting network performance.

protection

In DPM, the process of protecting data from loss or corruption by centrally creating and maintaining replicas and shadow copies of the data. DPM is designed to provide short-term disk-based backup, to support rapid and reliable recovery of data.

See Also: recovery

protection group

A collection of data sources that share the same protection configuration and schedule.

See Also: data source

protection group member

A data source within a protection group. A protection group member can be a share, volume, or folder.

recovery

In DPM, the process by which an administrator or end user recovers previous versions of shares, volumes, folders, or files from the shadow copies on the DPM server.

See Also: protection

recovery collection

The aggregate of all recovery jobs associated with a single recovery operation.

replica

A complete copy of the protected data on a single volume. Each volume in a protection group is associated with a replica on the DPM server.

replica creation

The process by which a full copy of data sources, selected for inclusion in a protection group, is transferred to the DPM storage pool. The replica can be created over the network from live data on the file server or from a tape backup system. Replica creation is an initialization process that is performed for each volume when the volume is added to a protection group.

replica volume

A volume on the DPM server that contains the replica and shadow copies for a protected volume.

Report database (ReportServer.mdf)

The SQL Server database that stores DPM reporting information.

ReportServer service

The local report service that manages, executes, renders, schedules, and delivers DPM reports.

ReportServer.mdf

In DPM, the file name for the Report database--a SQL Server database that stores reporting information.

restore
