詳細説明

The Set-DPMDatasourceDiskAllocation cmdlet changes disk allocation for protected data. By default, System Center 2012 – Data Protection Manager (DPM) allocates disk space and volumes for the data source. The cmdlet gives you these options for changing disk allocation:

-- Specify the amount of disk space to allot to each data source in a protection group.
-- Specify the volumes to use for each data source in a protection group.

パラメーター

-AutoGrow<Boolean>

Indicates whether DPM increases the size of the replica or recovery point volume automatically when it runs out of user space.

-CustomRequirements

Indicates that you can specify replica and shadow copy volumes manually.

-Datasource<Datasource>

Specifies a share or volume in a Windows file system, Microsoft SQL Server database, Microsoft Exchange storage group, Microsoft SharePoint farm, Microsoft virtual machine, DPM database, or system state that is a member of a protection group.

-DestinationDiskPool<Disk[]>

Specifies the set of disks on which DPM allocates volumes to migrate a data source. This parameter is migration specific.

-DestinationReplicaVolume<DpmServerVolume>

Specifies the destination volume that the user allocates to migrate replicas of a data source. This parameter is migration specific.

-DestinationShadowCopyVolume<DpmServerVolume>

Specifies the destination volume that the user allocates to migrate shadow copies of a data source. This parameter is migration specific.

-ExpectedDataSizePerClientInMB<Int64>

Specifies the expected size of data that the user will back up from each client computer (in megabytes).

-FormatVolumes

Indicates that DPM formats the allocated volumes.

-Manual

Indicates that you can apply DPM settings manually.

-MigrateDatasourceDataFromDPM

Indicates that DPM migrates the data source from the current volumes to a new set of volumes.

-PassThru

Indicates that cmdlets can be part of a pipeline. Use this parameter with other DPM cmdlets to return a related object in cases where the cmdlet does not create default output.

-ProductionServerJournalSize<Int64>

Specifies the journal size of the protected server.

-ProtectionGroup<ProtectionGroup>

Specifies a protection group object.

-ReplicaArea<Int64>

Specifies the disk allocation for the replica area of the current data source.

-ReplicaVolume<DpmServerVolume>

Specifies a replica volume object. A replica volume is a volume on the DPM server that contains the replica of a protected data source.

-ShadowCopyArea<Int64>

Specifies the disk allocation for the shadow copy area of the current data source.

-ShadowCopyVolume<DpmServerVolume>

Specifies an object for a shadow copy volume. This object represents the volume that contains the shadow copy.

-USNJournalSize<Int64>

Specifies the journal size for the update sequence number (USN).

例

Example 1: Specify disk allocation for a data source

This example specifies the disk allocation for a data source.

The first command gets all protection groups from the DPM server named TestingServer and stores these groups in the variable named $Pg. You cannot edit these protection groups.

The second command gets the protection groups from the $Pg array in editable mode. It stores the editable protection group in the variable named $Mpg.

The third command gets the list of protected and unprotected data from the $Mpg array and stores them in the variable named $Ds.

The fourth command gets the current disk allocation for the second data source in $Ds.

The fifth command sets the disk allocation for the second data source in $Ds from the protection groups in $Mpg.

The sixth command saves the second data source in $Ds to the editable protection group in $Mpg.

PS C:\> $Pg = Get-ProtectionGroup -DPMServerName "TestingServer"PS C:\> $Mpg = Get-ModifiableProtectionGroup $PgPS C:\> $Ds = Get-Datasource -ProtectionGroup $MpgPS C:\> Get-DatasourceDiskAllocation -Datasource $Ds[1]PS C:\> Set-DPMDatasourceDiskAllocation -Datasource $Ds[1] -ProtectionGroup $MpgPS C:\> Set-ProtectionGroup $Mpg
