DPM–Protection of SharePoint with DPM 2010

One of the common misunderstood made by DPM Backup Administrator is the sequence to be carried out in order to protect the SharePoint Server Farm.

• First, install the DPM agent on the SharePoint Web-Front End (WFE) Servers.
• Second, install the DPM agents on the Back End SQL servers.
• Thirdly, the SharePoint VSS must be enable.  The command to execute is with the switch as follow :
  • ConfigureSharepoint.exe –EnableSharePointProtection
  Note : – you must run the command line above in administrator mode in the SharePoint server.  You may need to change the directory to execute the command which is : C:\Program Files\Microsoft Data Protection Manager\DPM\bin>
  

Thank you and hope this helps you.

DPM–Problem with SQL Synchronization in DPM 2010

 

One of the interesting fact that I found in using DPM backing up SQL.

One database had a recovery model FULL couldn’t synchronize the log files content to DPM.

In the SQL server side, after going through the event viewer, realised that the event ID 5, Active Server Pages.  This error occurred at the same time as the backup.

Resolution : re-register the asp.dll from an elevated command prompt.

Thanks to Robert Hedblom for his sharing.

Hope this helps you as it helps me.

DPM–The VSS provider is in a bad state (ID 30111)

Today I would like to share information on VSS error in DPM I found useful  to first timers DPM Administrators.

In this scenario I have a Secondary DPM server backing up the Primary DPM server.

The Secondary DPM Server tried to do a Recovery Point Creation failed.

So the next thing that usually that a DPM administrator will do is to do a Inconsistency Check …. and guess what happens.  It failed too.

Well, there’s a trick here.  Check your Primary DPM server if there’s any Thumb Drive or Hard Drive attached to the USB port. 

Solution :

• Remove those storage from the USB ports (Primary DPM Server).
• Do a Consistency Check again in the Secondary DPM Server.
• Once completed, then do a Recovery Point Creation in the Secondary DPM Server.

Issue solved !!  

Hope it helps you.  Thank you.

DPM–Can’t Remove Protected Computer in DPM Console

Today I receive a request that the DPM agent was installed into a protected computer is no longer needed and needs to be remove from the DPM.

Somehow, they hit an issue.  They can’t uninstall the Agent from the DPM server. 

First of all, you need to check that there’s no protection group exist for that particular server anymore in the DPM.

Next is go to the Protected Computer and ensure that there’s no DPM agent installed.  Go to the Add or Remove Programs and uninstall the DPM agent.

Once this is done, go back to the DPM server and launch the PowerShell for DPM.

• Key in remove-productionserver.ps1 from the powershell and hit <Enter>
• Key in the DPM Server name that is protecting the server in the DPM Server name after the DPMServer:: and hit <Enter>
• Key in the Protected Server (that is to be remove from the DPM database) after the PSName:: together with the FQDN (meaning the computername plus the full domain name) and hit <Enter>

Once it’s removed, just bring back the DPM Console and go to the Management – Agents.  You’ll no longer see the computer that was removed using the PowerShell anymore.

Thank you and hope this helps you as much it helps me.

DPM–Protecting Exchange (Replica is Inconsistent)

The DPM will not be able to backup the Exchange if the Replica is Inconsistent .

Firstly is to check if the Space Allocated is sufficient in the DPM.  If it’s not then you have to allocate more space or to reduce the short term retention period to gain more space.

I tried to simulate a situation that one of the environment is facing the issue. 

The “Run Eseutil to check data integrity” was checked in the DPM, however the logs in the DPM prompted as “Replica is inconsistent”

All protection group activities for the data source will fail until the replica is synchronized with consistency check.  The error would be 0x800700D8 and a reference to ID 30146.

After some investigation, found that the Eseutil.exe and Ese.dll that are installed in the Exchange is different version from the DPM.

So what I did was to copy the Eseutil.exe and Ese.dll files from the Exchange to the
"<drive>:\Program Files\Microsoft Data Protection Manager\DPM\Bin" directory on the Data Protection Manager server

Take note :  One thing to take note is the version of Exchange.  You have to copy the correct version (32-bit or 64-bit) of the Eseutil.exe & Ese.dll to the DPM server.  If have upgraded to the Exchange Service Pack, then you have to copy the latest Eseutil.exe & Ese.dll from the Exchange Server to the DPM directory as mentioned above in green above.

Thank you and hope this helps.  The findings above is from the Technet & Forums.

DPM–Access denied in Windows Explorer after mountvol in CMD

Here I am login in as a domain user  that is also a member of the of the LOCAL ADMINISTRATORS group in a server. 

I manage to MOUNTVOL and assign a letter K to the volume.  It’s for a site-to-site replica manual transfer.  For those of you that is interested in the site-to-site replica manual transfer, it’s in my blog too .

Before I go further, here’s some short explanation on the UAC from Technet :

To help prevent malicious software from silently installing and causing computer-wide infection, Microsoft developed the UAC feature. Unlike previous versions of Windows, when an administrator logs on to a computer running Windows Server 2008, the user’s full administrator access token is split into two access tokens: a full administrator access token and a standard user access token.

During the logon process, authorization and access control components that identify an administrator are removed, resulting in a standard user access token. The standard user access token is then used to start the desktop, the Explorer.exe process.

Because all applications inherit their access control data from the initial launch of the desktop, they all run as a standard user as well.

After an administrator logs on, the full administrator access token is not invoked until the user attempts to perform an administrative task.

Anyway, if you have the LOCAL ADMINISTRATOR’s password you can go through the steps mentioned earlier in my blog.  However, in some situation there’s no way to have the LOCAL ADMINISTRATOR’s password. I’m already assigned as part of the local administrators group.

So after some snooping around and found that the issue is with the User Access Control (UAC).

So what I did is to edit the registry of the DPM server :

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

Change the EnableLUA from 1 to 0

Reboot the server.

Login with the user that is part of the Local Administrators Group.

Perform the steps to MOUNTVOL & then from the Windows Explorer, you can be able to access the volume with the letter assigned.  Copy the necessary data out to external drive to transport out to second site and copy the data from the external drive to the secondary DPM server.

More information on the UAC is in here.

Please note : That should make admins run as admins all of the time. This is dangerous and I would recommend that you enable this feature back on for day to day use.

Thank you & hope this helps you .

DPM–More of BMR (Error 0x80070057)

When doing the restoration for the BMR, it’s very important to note the following :

You can't do an image restore unless ALL the drives are exactly as they were. Meaning when I was using USB drive to initiate the recovery, it was counting that as a drive. So no go on using a jump drive to initiate the Windows Recovery Environment. That was what was the "the parameter is incorrect; 0x80070057" error.

So I figured a workaround.  Once you have selected the network driver to be installed and also the shared network drive where the DPM recovery image is stored, you then eject the thumb drive, before you click FINISH in the end for the restoration process.  That will do the trick.

Hope this helps you .

DPM–Backing Up Hyper-V (Consistency Check Error)

Today I had an issue of backing up the Hyper-V through the DPM 2010.  The agent is installed into the Hyper-V host.  There’s also ample of space in the drive where the VHDs resides.  The same drive also caters for the snap shots. 

When I execute the Consistency Check it states that DPM failed to synchronize changes for Microsoft Hyper-V \Backup Using Child Partition Snapshots\VMServername on Hyper-VServerName because the snapshot volume did not have sufficient storage space to hold the churn on the protected computer (ID 30115 Details : VSSError : Insufficient storage available to create either the shadow copy storage file or other shadow copy data. (0x08004231F))

Status is Failed.

Therefore I carried out the steps below to have it working.

Step 1 (to be perform in Hyper-V Host)

• Open the the Registry.
• Add in the key :
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent\UseSystemSoftwareProvider

 

Step 2 (to be perform in the DPM Server)

• From the Command prompt (Run as Administrator), key in the command to stop the DPM and restart the DPM services.  The command are as follow :
  
  net stop dpmra
  
               then to start the DPM service
  
  net start dpmra
  
  

Perform the Consistency Check once more.  Once it’s completed, then you can Create recovery point for restore.

Thank you and hope it helps you.

DPM – What is Initial Store ?

When you use the DPM to backup a Hyper-V Server, there’s a check box for Initial Store. What is that … you may wonder.

The initial store contains the security permissions for Hyper-V’s Authorization Manager (AzMan).  This is an xml file located in %systemdrive%\ProgramData\Microsoft\Windows\Hyper-V\. You only need to perform a restore if this xml file becomes corrupted or is deleted. 

Backing up virtual machines and the initial store are independent. You only need to back up the initial store if you are using the Authorization Manager in Hyper-V and don’t want to lose your settings.

For more information on Hyper-V Authorization Manager visit: http://technet.microsoft.com/en-us/library/dd283076(WS.10).aspx

How to have Intergration Service working in Linux for Hyper-V

Today I’m going to share with you that you can have Linux install into the Hyper-V.

I’ve here is the Suse Linux 10 installed as a VM in my Hyper-V lab.

Need to take note, that the Network should be installed as Legacy Network Adapter during the provisioning of the Linux VM (if it’s not in the listed as supported Linux version in Hyper-V). Otherwise can use the Synthetic Network Adapter. 

In the version of Suse Linux 10, the Synthetic Network Adapter is use then.

Intergration Services

Once you’ve installed the Linux, you need to install the “Intergration Services”.

You can download it from here.

Download both the files (the Linux_IC_v2.EXE & Linux Integration Components Read Me.pdf)

1. Open Hyper-V Manager

2. In Hyper-V Manager, configure LinuxIC v2.ISO (located in the directory where you extracted the downloaded files) as a physical CD/DVD drive on the virtual machine.

3. As the root user, mount the CD in the virtual machine by issuing the following commands at a shell prompt:

# mkdir /mnt/cdrom

# mount /dev/cdrom /mnt/cdrom

4. Copy the Linux Integration Components to the virtual machine.

# mkdir /opt/linux_ic_rtm

# cp /mnt/cdrom/* /opt/linux_ic_rtm –R

5. As the root user, run the following command to install the synthetic drivers.

# /opt/linux_ic_rtm/setup.pl drivers

Getting Mouse Working

Next is to get the MOUSE working.

Download the ISO file from here.

1. Download and attach the .ISO file to a Hyper-V guest with the Linux Integration Components already installed.

2. Copy the contents of the .ISO to the desired directory

3. Run setup.pl with the inputdriver argument:

# ./setup.pl inputdriver

You might need to reboot the Linux VM if the mouse is not working.

Thanks to my comrade Kwan Thean Keong for the recommendation.

More on Bare Metal Restore (DPM 2010)

I’ve some query whether the DPM 2010 (BMR features) can be able to restore Physical to another physical which is not similar specs.

DPM 2010 utilizes Windows backup feature for both SystemState and BMR backups. The support for restoring to dissimilar hardware is defined by Windows and generally speaking, it not supported.  

BMR for Windows 2003 is only possible by using the DPM System Recovery Tool (SRT) a separate installable product that shipped on the DPM 2007 and DPM 2010 installation media.

In either case, nothing is preventing you from restoring to dissimilar hardware, but as noted it isn't supported and may not work 100% of the time (this most probably due to the different hardware drivers, which you may have to reinstall manually) .

For Windows 2003, it has been suggested is the right one like using the SRT for BMR backups. But for Windows 2008 and later OS versions, You can safely rely on the Windows Backup to restore on alternate hardware as well, it is much reliable than earlier Windows 2003 BMR / ASR (another method of System State Backup) recovery.

But some important points note here are, the recovery target has to have higher disk configuration than the backed-up one. If you are restoring a 32 Bit OS backup then you need to use 32 bit Setup/Install media/WINRE media(and same for 64 bit as well).

(WINRE stands for – Windows Recovery Environment)

To be able able to do successful BMR recovery, you have to backup all critical volumes using -allcritical options of Windows backup (DPM uses this option so all DPM BMR backups are BMR able, but it will not have data volumes backup).

Please note that A DPM server cannot protect itself for BMR.

It’s not so straight forward however it’s not impossible.

DPM–How to Erase the Tapes Manually before expire to be reuse.

I come across one of the many questions, someone asked me if they can erase the tapes manually before it’s expired.  They said they wanted to do some testing to backup to tapes but somehow they can’t be able to find the erasure in the GUI.

So I’m going to share how it is done using PowerShell.

 

Launch the DPM console.  Navigate to the Management – Libraries .  Take note of it.  Slot 1 to Slot 9 .

Then now open a notepad.  Copy and paste the following (in yellow) to it :

param ([string] $DPMServerName, [string] $LibraryName, [string[]] $TapeLocationList)

if(("-?","-help") -contains $Args[0])
{
Write-Host "Usage: ForceFree-Tape.ps1 [[-DPMServerName] <Name of the DPM server>] [-LibraryName] <Name of the library> [-TapeLocationList] <Array of tape locations>"
Write-Host "Example: Force-FreeTape.ps1 -LibraryName "My library" -TapeLocationList Slot-1, Slot-7"
exit 0
}

if (!$DPMServerName)
{
$DPMServerName = Read-Host "DPM server name: "
if (!$DPMServerName)
{
Write-Error "Dpm server name not specified."
exit 1
}

}
if (!(Connect-DPMServer $DPMServerName))
{
Write-Error "Failed to connect To DPM server $DPMServerName"
exit 1
}

$library = @(Get-DPMLibrary $DPMServerName )
if ($library.count -eq 0)
{
Write-Error "Failed to find library with user friendly name $LibraryName"
exit 1
}

if (!$LibraryName)
{
$library | foreach {$_.userfriendlyname}
$LibraryName = Read-Host "Library name (cut & paste from above): "
if (!$LibraryName)
{

Write-Error "Library name not specified."
exit 1
}
}

if (!$TapeLocationList)
{
$tmp = Read-Host "Tape location: "
$TapeLocationList=$tmp.split(",")
write-host "Processing this slot list..."
$TapeLocationList
if (!$TapeLocationList)
{
Write-Error "Tape location not specified."
exit 1
}
}

foreach ($media in @(Get-Tape -DPMLibrary $library))
{
if ($TapeLocationList -contains $media.Location)
{
if ($media -is [Microsoft.Internal.EnterpriseStorage.Dls.UI.ObjectModel.LibraryManagement.ArchiveMedia])
{
foreach ($rp in @(Get-RecoveryPoint -Tape $media))
{
Get-RecoveryPoint -Datasource $rp.Datasource | Out-Null
Write-Verbose "Removing recovery point created at $($rp.RepresentedPointInTime) for tape in $($media.Location)."
Remove-RecoveryPoint -RecoveryPoint $rp -ForceDeletion -Confirm:$false
}

Write-Verbose "Setting tape in $($media.Location) as free."
Set-Tape -Tape $media -Free
}
else
{
Write-Error "The tape in $($media.Location) is a cleaner tape."
}
}
}

 

Save the file and rename it with the extension .ps1

In my example here, I have a file name as Tape_Erase.ps1 and stored in the D:\PowerShell Scripts directory.

From the DPM console, I launch the DPM Management Shell (which is the PowerShell)

Once launch you’ll be able to see the screen as above.

Then I change to the directory to where I save my PowerShell Script.  In my case I maneuvered to “D:\PowerShell Scripts”.

To execute the PowerShell script I keyed in with a ./

In my example my file is name as tape_erase.ps1.  To execute the script I type as ./tape_erase.ps1 .

Then next I keyed in the DPM server name (that is with the tape library).  In my case is MY-VM-DPM-SEC01

Then I key in the tape slot that I want to erase the tape.

I keyed in as Slot-2. 

Note : the ones in pink are the ones that needs to be change accordingly to your naming of your PowerShell script and your DPM settings.

Then  you’ll be able to see the process followed.

Another example as above, which I want to erase the tape in Slot-9.  e.g. In some cases the name of slot could be Slot-9 or Slot 9.  So it differs from one tape library to another.

Once it’s done, launch back the DPM Console.

Click on the Management tab, then on the Libraries tab.

Select the tape that was erase earlier.  In my example is Slot 2.  <Right-click> on the tape and select Erase tape.

Click Yes.

Now the tape is erased and ready to be reuse.

Thank you and hope it helps you.  A special thanks also to Ruud Baars (of Microsoft) for sharing his scripting.

DPM–Manual Transfer of Replica (from Server with DPM Agent to DPM Server through the WAN) for protected folder(s).

 

Today I would like to share with you a scenario that I’ve tested out. 

I have a file server which is located in a branch and is is installed with a DPM agent across a WAN.

In summary the servers are :

• MY-VM-SVR-FS003 (File Server)
• MY-VM-DPM-PRI02 (Primary DPM Server)

The assumption is that the DPM agent has been deployed to MY-VM-SVR-FS003.

Site 2

Next is the creation of the Protection Group.

During the process of creating the Protection Group, the Choose replica creation method, select Manual and click Next

In my example , The protection group created is to protect a folder in MY-VM-SVR-FS003 i.e. D:\for Backup_FS003

As the diagram above, it shows “Manual replica creation pending”.

Now, we’ll go to another site which MY-VM-SVR-FS003 is located e.g. Site 1 in my scenario.

Site 1

Copy the folder that was specified to an external media, e.g. external Hard Disk.

Once it’s done, we’ll go back to Site 2 with this copied media.

Back to Site 2

In the MY-VM-DPM-PRI02 , launch the DPM Console. Go to the Protection Group, select the protected group.  In my case is the MY-VM-SVR-FS003-Remote.

Note : login to server as LOCAL ADMINISTRATOR but launch the DPM console with the account that is part of the domain.  In my case I use MY-DPM-SVC domain account.

Click to view details.

<Right-click> on it and select Copy. 

Open up Notepad and copy into it for reference later.

Next, open command prompt.

Type mountvol .

Note the same volume between the notepad and the command prompt.

Highlight and copy.

type mountvol k:\ \\?\Volume{00e2fe0c-9e3b-11e0-86aa-00155da84d01}\

The command is to mount the volume into K Drive. 

note : What is shown in pink will be different from one DPM to another.

Next, open up Windows Explorer.

You’ll be able to see the K Drive.  Double click to expand it.

Expand the K Drive, and expand the folder.

Paste what has been copied from Site 2 to this particular directory (from the external media).

Copy and replace it.   Click Yes.

Once the copying is completed, go back to the command prompt.

Type mountvol k: /d to remove the the volume from K Drive.

In the DPM Console, Perform consistency check …

Very fast the consistency check is completed.  (it took a couple of seconds for my testing).  So now only the changes is replicated rather the entire chunk across the WAN.

Thank you and hope it helps you .

DPM–Site to Site Replication (How to Manual Transfer of Large Volume Data )

 

Here I have 2 servers (both are in the same domain).  They are :

• MY-VM-DPM-PRI01 (Primary DPM Server)
• MY-VM-DPM-SEC01 (Secondary DPM Server)

The Secondary DPM Server will need to replicate from the Primary DPM Server as a backup.  However it’s going through the WAN and transferring a huge data through the WAN will take a very long time and will consume the WAN bandwidth for other purpose.

The recommended way is to transfer the data manually from the site 1 server MY-VM-DPM-PRI01 to a media (e.g. an external hard disk) then transport the media to site 2 and import into the MY-VM-DPM-SEC01 server.

By following the steps that I’m going to share, you’ll be able to perform the task easily.

Firstly the MY-VM-DPM-PRI01 needs to be part of MY-VM-DPM-SEC01 protected computer.

This can be done by deploying the agent from MY-VM-DPM-SEC01 to MY-VM-DPM-PRI01.

Once it’s done, you’ll be able to see as follow in MY-VM-DPM-SEC01 :

In Site 2

In the MY-VM-DPM-SEC01, I launch the DPM console and then, when create a protection group.  Then I select the All SQL Servers (in MY-VM-DPM-PRI01) for this example. 

You can drill down further on what the MY-VM-DPM-PRI01 – All Volumes to see what the MY-VM-DPM-PRI01 server is protecting other servers.  You can Check or Uncheck for what is to be replicated to MY-VM-DPM-SEC01.

When coming to the Choose replica creation method, select Manually cause it’s through the WAN.  We wouldn’t want to do a huge replication through the WAN, right ?

Once you’ve finished the creation of the Protection Group, you’ll be able to see the following :

Now we’ll go to Site 1, to perform the copy of data manually.

In Site 1.

Login to the MY-VM-DPM-PRI01 as LOCAL ADMINISTRATOR.

Launch the DPM by <right-click> on the DPM Console and Run as different user

In this case I login with the user that is use for the installation of the DPM (which is part of the domain, and has rights to the servers that is protecting).

Select Click to view details.

<Right-click> select Copy.

Open a Notepad and paste into it.  This information will be use later.

Select the Command Prompt – <right-click> – Run as administrator.

In the command prompt type mountvol.

Look for the value and compare between the notepad and the command prompt.  As shown above is in (1) and (2) .

Then you need to highlight and copy as shown above (the GUID will differ from one DPM to another).

Type mountvol k:\ \\?\Volume{3e4c956d-95f7-11e0-95ec-00155da84202}\

Note : The one that is showing in the pink colour is your value that will be different. 

Open up the Windows Explorer.  Need to open up the Folder Options from the Menu Bar

Select the Folder options.

In the Folder Options, click on the View tab.

The Uncheck the Hide protected operating system files (Recommended) and click OK.

Back to the Windows Explorer, copy all the content in the K drive to external media or device e.g. a Hard Drive to be transported to site 2.

Once it’s done, open up the command prompt and type :

mountvol k: /d

This will release the volume for the DPM from K Drive.

Open up the Windows Explorer to verify the volume is dismounted.

Once that is done, it’s time to go to site 2 with the external media.

Back to Site 2.

Now I login to the MY-VM-DPM-SEC01 as LOCAL ADMINISTRATOR.

Launch the DPM by <right-click> on the DPM Console and Run as different user

In this case I login with the user that is use for the installation of the DPM (which is part of the domain, and has rights to the servers that is protecting).

Click to view details from the Details of the Protected Group.

<Right-click> and select Copy.

Open the notepad and copy into it for later reference.

Select the Command Prompt – <right-click> – Run as administrator.

In the command prompt type mountvol.

Locate for the GUID that is similar in the notepad and compare with the command prompt.  (1) and (2) as shown above.

Then you need to highlight and copy as shown above (again the GUID will differ from one DPM to another).

Type mountvol l:\ \\?\Volume{64d6d785-98a8-11e0-b967-00155da8ef00}\

Note : The one that is showing in the pink colour is your value that will be different.

Open the Windows Explorer, then go to the Menu Bar and select Folder Options (if the Windows Explorer doesn’t show the Menu Bar, then press <Alt> , the Menu Bar will open)

In the Folder Options, click on the View tab.

The Uncheck the Hide protected operating system files (Recommended) and click OK.

From the external drive transported from Site 1, copy all it’s content.

and paste into the L Drive that was mounted in the MY-VM-DPM-SEC02.

Once the copying is completed, open up the command prompt (that was open earlier).

In the command prompt, type mountvol l: /d .  This will release the volume from L Drive that was assign.

Open up the Windows Explorer to verify the L Drive is no longer mounted.

Open up the DPM Console, then maneuver to the Protection Group.

Then <Right-Click> to Perform consistency check.  This will compare the MY-VM-DPM-PRI01 & MY-VM-DPM-SEC01 data. 

Click Yes.

Now the consistency check is done.  The data between MY-VM-DPM-PRI01 & MY-VM-DPM-SEC01 both are the same.

Thank you and hope it helps you.
