Detailed Description

The Set-DPMDatasourceDiskAllocation cmdlet modifies disk allocation for the protected data.

Using the -Manual parameter you can specify the amount of disk space to allot to each data source in a protection group.

Using the -CustomRequirements parameter you can specify the volumes to use for each data source in a protection group.

If you use neither parameter, DPM will assign the default disk space and volumes for the data source.

Parameters

-AutoGrow<Boolean>

Indicates whether the replica or recovery point volume size should be increased automatically when the user space threshold is exceeded.

Aliases	none
Required?	true
Position?	2
Default Value	none
Accept Pipeline Input?	True (ByValue)
Accept Wildcard Characters?	false

-CustomRequirements

Allows you to specify replica and shadow copy volumes manually.

Aliases	none
Required?	true
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-Datasource<Datasource>

Provide a Windows file system share or volume, 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.

Aliases	none
Required?	true
Position?	1
Default Value	none
Accept Pipeline Input?	True (ByValue)
Accept Wildcard Characters?	false

-DestinationDiskPool<Disk[]>

Specify the set of disks on which DPM will allocate volumes for migration of a data source. This parameter is migration specific.

Aliases	none
Required?	true
Position?	4
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-DestinationReplicaVolume<DpmServerVolume>

Specify the destination volume allocated by the user for migrating replicas of a data source. This parameter is migration specific.

Required?	true
Position?	4
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-DestinationShadowCopyVolume<DpmServerVolume>

Specify the destination volume allocated by the user for migrating shadow copies of a data source. This parameter is migration specific.

Aliases	none
Required?	true
Position?	5
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-ExpectedDataSizePerClientInMB<Int64>

Provide the expected size of data to be backed up from each client computer (in MB).

Aliases	none
Required?	true
Position?	named
Default Value	none
Accept Pipeline Input?	True (ByValue)
