DPM: How to protect a specific folder with PowerShell

In this guide we will go through on how to add a specific folder to a protection group using PowerShell.

The DPM console can sometimes be slow, if you want to do something quick you might choose to use the DPM Shell or PowerShell.

Almost everything that you can do within the DPM console, you can also do with PowerShell, you can find all of the DPM PowerShell cmdlets from the Microsoft docs page: DataProtectionManager

 

Overview of the environment

Before getting into adding workloads to my protection group, we will quickly have a look at our environment.

Environment details

We have a server called “DC01” that is currently being protected in our DPM 1807, our “DC01” server is currently being protected in a protection group called “DC Protection Group”, currently there’s only one (1) folder in the protection group.

OS version: Windows Server 2016

DPM version: 1807

Protected computer: DC01

Protection Group: DC Protection Group

 

Protecting a specific folder using PowerShell

  1. Let’s start by opening up a PowerShell (Run as administrator).
  2. We will now import the DPM PowerShell module by typing:
    Import-Module DataProtectionManager

  3. We will now create a variable called $PG (short for “protection group”) and define our protection group “DC Protection Group” as follows:
    $PG = Get-DPMProtectionGroup -DPMServerName “DPM” | Where-Object {$_.FriendlyName.ToUpper() -eq “DC Protection Group”}

  4. Let’s check what our $PG variable returns:
  5. Next we will create a variable called $PS (short for “production server”) where we will define the server where our datasource is located on.
    $PS = Get-DPMProductionServer -DPMServerName “DPM” | Where {$_.ServerName -eq “DC01”}

  6. Here’s what our $PS variable returns:
  7. Now we will create a variable called $DS (short for “datasource”) and get the datasource from our production server that is stored in the $PS variable we created in the previous step.
    $DS = Get-DPMDatasource -ProductionServer $PS -Inquire

  8. The $DS variable returns everything found in the datasource:
  9. In this guide we will choose to protect a specific folder from the C:\ drive, so we will select this drive as follows:
    $DS = Get-DPMDatasource -ProductionServer $PS -Inquire | Where {$_.Name -eq “C:\”}

  10. If we now check what’s stored in the $DS variable, it now only returns the C:\ drive:
  11. We have defined the C:\ drive datasource, we will now create another variable called $PO (short for “protected objects”) that will inquire the items within the C:\ drive and store it to the $PO variable.
    $PO = Get-DPMChildDatasource -ChildDatasource $DS -Inquire

  12. Our $PO variable contains the following objects:
  13. Now we’ll create a variable called $MPG (short for “modifiable protection group”) that will get our protection group “DC Protection Group” in editable mode:$MPG = Get-DPMModifiableProtectionGroup $PG
  14. The $MPG variable will now return our “DC Protection Group”:
  15. We will now add the folder we want to our “DC Protection Group”, in step 12 we have listed the different folders that were found under the C:\ drive of our server DC01. The list is an array, so that means that numbering will start from 0, 1, 2, 3… and so on. We want to add the Recovery folder, if we now count from 0, the Recovery folder would have number 6.
  16. Now that we have identified the number in the array, we will add it to our “DC Protection Group” as follows:
    Add-DPMChildDatasource -ProtectionGroup $MPG -ChildDatasource $PO.Item(6)

  17. Since we have the “DC Protection Group” in editable mode we will now have to save our changes, this can be done by using the
    Set-DPMProtectionGroup cmdlet.

    Set-DPMProtectionGroup -ProtectionGroup $MPG

  18. We are now done with the PowerShell so we can disconnect our DPM shell session.
    Disconnect-DPMServer

  19. Let’s go and have a look in the System Center DPM Administrator Console to verify that our Recovery folder has successfully been added to our “DC Protection Group”.

And there it is, we have now successfully added a folder to a protection group by using PowerShell!
