You may want to create custom PowerShell PS1 scripts that make use of the Data Protection Manager (DPM) commandlets. In order to be able to use the DPM cmdlets, basically, you must Import-Module DataProtectionManager.psd1.
You can do it two differente ways. Either load directly the full default initialization script which shows welcome banner and some initial help about DPM cmdlets - the one which is loaded from the GUI shortcut:
C:\Program Files\Microsoft System Center 2012\DPM\DPM\bin\dpmcliinitscript.ps1
Or simply load the DataProtectionManager.psd1 module directly. If you looked into the previously mentioned initialization script DpmCliInitScript.PS1, you would see the following three, very nicely generic, lines:
$installPath = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Setup" "UIInstallPath").UIInstallPath
$dpmModuleFullPath = $installPath + "Modules\DataProtectionManager\DataProtectionManager.psd1"
