DPM–Remove Untrusted Machines from Agents Tab in DPM

Today, I’m going to share on how you can remove the UNTRUSTED machine from the agent tab in DPM 2010

The uninstall option is not available in the DPM 2010.  So have to carry out the following :

In the protected machine, you need to go to Control PanelAdd and Remove Programsuninstall the DPM program.

Then in the DPM 2010, launch the DPM 2010 Powershell and execute the command remove-productionserver.ps1.


Note : If the Netbios name doesn’t work, then key in the computer plus the FQDN.

Thank you and hope this helps you .

DPM–Co Location of Tape in DPM


Today I’m sharing on how you can utilize your tapes by co-locating the tapes. 

There are other backup software that uses the same tape and does the compression, append it and do lots of nice stuff to fit the data into the tape. 

However DPM keeps it simple and that’s a good thing.  This is useful if you have lots of small protection group.

There are some rules that needs to follow when using the co-location to tape:

  1. You cannot apply co-location selectively. If enabled, it applies to all protection groups.
  2. Only protection groups with the same retention period can be co-located on the same tape.
  3. Encrypted and non-encrypted datasets cannot be co-located on the same tape.
  4. Datasets from different vaults cannot be co-located on the same tape.

If the condition above is okay then open the DPM PowerShell and type:

Set-DPMGlobalProperty –DPMServerName MYDPMSVR -OptimizeTapeUsage $True

Note : just replace the letter in GREEN with your DPM server name.  The rest of the command stays.

Thank you & hope it helps you.
