A new add-on for DPM: dBeamer!DPM

4:55 pm in Uncategorized by mikeresseler

It seems that there is a new add-on available for system center data protection manager. 

The add-on is called dBeamer!DPM and according to their website, it transforms DPM into a central component of a High-Availability – On-Demand infrastructure.  This of course drew my attention :-).

So I went further with reading the information

With the add-on, DPM administrators are able to browse data history captured in DPM and perform an instant data recovery from Microsoft DPM at anytime.

Ok, this is getting more interesting ;-).

The add-on allows you to start the recovery process, and instantly allows you to use the data, while the recovery process is still busy.  And even databases that are being recovered can be used instantly while the recovery is still in progress.

With dBeamer!DPM, you can even recover data from the DPM repository without the DPM service is actually running or present…

And with the fact that you can start your services (such as SQL) or your VM’s while the recovery is still in progress, make modifications to the data, it gives IT administrators a RTO of almost nothing.

Now this information comes from the website of instavia, which is the company that made the software.  I haven’t tested it out yet (I’m going to send an email asking for a test as soon as possible :-)) but it certainly seems promising.  If all above is true, then you can have a killer tool together with DPM.

Hopefully I get a test / demo license and I can give you more information soon

Cheers,

Mike

From the Forums: Could not enumerate Exchange

8:50 am in Uncategorized by mikeresseler

Here’s a strange case that has been discussed on the great DPM forums.

A user reported that he could not enumerate the Exchange server when he was creating a protection group for Exchange Server using the DPM wizard.

These are the errors he got:

DPM could not enumerate application component Microsoft Exchange Server\Microsoft Information Store\xxx\17a465cc-90ca-4abd-927f-9aed49f33b5e on protected computer xxx. (ID: 964)
Please make sure that writer is in good state.

DPM could not enumerate application component Microsoft Exchange Server\Microsoft Information Store\xxx\17a465cc-90ca-4abd-927f-9aed49f33b5e\File on protected computer xxx. (ID: 964)

DPM could not enumerate application component Microsoft Exchange Server\Microsoft Information Store\xxx\17a465cc-90ca-4abd-927f-9aed49f33b5e\Logs on protected computer xxx. (ID: 964)
Please make sure that writer is in good state.

We let him do all the usual stuff but it didn’t solved anything.

Until today, nothing was found to solve this case, and there were many more reporting this issue.  But today, a user named Frans Molenaar found a solution.  Although it sounds like a very strange solution which has nothing to do with the issue, I decided to test it out in my sandbox and come to the conclusion that it actually indeed solved the case.

So here goes:

First: Check on the exchange server if the following powershell scripts exist:

In  %ExchangeInstallPath%\bin you need to find the following scripts:

  • CommonConnectFunctions.ps1
  • CommonConnectFunctions.strings.psd1
  • Connect-ExchangeServer-help.xml
  • ConnectFunctions.ps1
  • ConnectFunctions.strings.psd1
  • RemoteExchange.ps1
  • RemoteExchange.strings.psd1

Second: Check the following registry keys if they exist:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns]
@=””

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns\Microsoft.Exchange.Management.PowerShell.E2010]
“CustomPSSnapInType”=”Microsoft.Exchange.Management.PowerShell.AdminPSSnapIn”
“ApplicationBase”=”C:\\Program Files\\Microsoft\\Exchange Server\\V14\\bin”
“AssemblyName”=”Microsoft.Exchange.PowerShell.Configuration, Version=14.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35″
“Description”=”Admin Tasks for the Exchange Server”
“ModuleName”=”C:\\Program Files\\Microsoft\\Exchange Server\\V14\\bin\\Microsoft.Exchange.PowerShell.Configuration.dll”
“PowerShellVersion”=”1.0″
“Vendor”=”Microsoft Corporation”
“Version”=”14.0.0.0″

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns\Microsoft.Exchange.Management.PowerShell.Setup]
“CustomPSSnapInType”=”Microsoft.Exchange.Management.PowerShell.SetupPSSnapIn”
“ApplicationBase”=”C:\\Program Files\\Microsoft\\Exchange Server\\V14\\bin”
“AssemblyName”=”Microsoft.Exchange.PowerShell.Configuration, Version=14.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35″
“Description”=”Setup Tasks for the Exchange Server”
“ModuleName”=”C:\\Program Files\\Microsoft\\Exchange Server\\V14\\bin\\Microsoft.Exchange.PowerShell.configuration.dll”
“PowerShellVersion”=”1.0″
“Vendor”=”Microsoft”
“Version”=”14.0.0.0″

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns\Microsoft.Exchange.Management.Powershell.Support]
“CustomPSSnapInType”=”Microsoft.Exchange.Management.Powershell.Support.SupportPSSnapIn”
“ApplicationBase”=”C:\\Program Files\\Microsoft\\Exchange Server\\V14\\bin”
“AssemblyName”=”Microsoft.Exchange.Management.Powershell.Support, Version=14.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35″
“Description”=”Support Tasks for the Exchange Server”
“ModuleName”=”C:\\Program Files\\Microsoft\\Exchange Server\\V14\\bin\\Microsoft.Exchange.Management.Powershell.Support.dll”
“PowerShellVersion”=”1.0″
“Vendor”=”Microsoft Corporation”
“Version”=”14.0.0.0″

If this is not the case, then copy the registry keys from another exchange server and after that, it works.

To test this, I exported some of the registry keys, removed them and tried the DPM wizard.  I got exactly the error as described in the thread.  After imorting the keys again, everything worked as a charm.

If you have this similar issue, then check these things out

And thank you Frans Molenaar for finding this solution

Configuring Cluster Networks for CSV redirected access

7:55 am in Uncategorized by mikeresseler

Here’s a great article published by Microsoft:

System Center Data Protection Manager 2010 Hyper-V protection: Configuring cluster networks for CSV redirected access

Those of you who have ever worked with DPM 2010 and the protection of hyper-v guests, located on a CSV know that this could be a pain in the …

We have seen many reports on dying clusters, non-performing servers and so on.

The first option is, and always is, make sure that you het the hardware VSS provider (http://blogs.technet.com/b/dpm/archive/2010/02/05/tested-hardware-vss-provider-table.aspx)

But sometimes it is just not possible (there is no VSS provider, or it is not compatible)

Second option would be to serialize the backup of the virtual machines. (Great article by Robert here: http://robertanddpm.blogspot.com/2010/07/enabling-serialized-backup-of-hyper-v.html)

And even further, the article published now gives a great overview on how and why you should have a dedicated network for redirected mode.
