Set-DPMPerformanceOptimization
Set-DPMPerformanceOptimization
Enables or disables on-the-wire compression for a DPM protection group.
Syntax
Parameter Set: DisableCompression
Set-DPMPerformanceOptimization [-ProtectionGroup] <ProtectionGroup> -DisableCompression [-PassThru] [-Confirm] [-WhatIf] [ <CommonParameters>]
Parameter Set: EnableCompression
Set-DPMPerformanceOptimization [-ProtectionGroup] <ProtectionGroup> -EnableCompression [-PassThru] [-Confirm] [-WhatIf] [ <CommonParameters>]
Detailed Description
The Set-DPMPerformanceOptimization cmdlet enables or disables on-the-wire compression of data for a System Center 2012 – Data Protection Manager (DPM) protection group. You can use the Get-DPMProtectionGroup cmdlet to get a protection group, and use the Get-DPMModifiableProtectionGroup cmdlet to allow changes for a protection group.
On-the-wire compression decreases the amount of data transferred during replica creation, synchronization, and consistency check operations. On-the-wire compression increases CPU usage on both the DPM server and on protected computers.

Examples
Example 1: Enable compression for a protection group
This example enables on-the-wire compression of data for all data sources protected in the specified protection group. The first command uses the Get-DPMProtectionGroup cmdlet to get the protection group for the DPM server named DPMServer07, and stores that object in the $DPMPG variable.
The second command uses the Get-DPMModifiableProtectionGroup cmdlet to get the protection group stored in the $DPMPG variable in an editable format, and stores that object in the $DPMMPG variable.
The third command enables compression for the protection group stored in the $DPMMPG variable.
PS C:\> $DPMPG=Get-DPMProtectionGroup -DPMServerName "DPMServer07"
PS C:\> $DPMMPG = Get-DPMModifiableProtectionGroup -ProtectionGroup $DPMPG
PS C:\> Set-DPMPerformanceOptimization -ProtectionGroup $DPMMPG -EnableCompression
