Update Rollup 9 for System Center 2012 R2 Data Protection Manager is now available!

Hi!

Update Rollup 9 has been released and for all the DPM-admin out there. Here is the fix we all have been waiting for:

• No production server restart is required when you upgrade from DPM 2012 R2 Update Rollup 6 or later versions!

"We have performed an extensive review of the DPM architecture to avoid production server restarts when you upgrade the DPM Agent. There were a few cases in which the Agent update was flagging for restart, and these are fixed now. Therefore, if you already upgraded to DPM 2012 R2 Update Rollup 6 or a later version, you will not experience a restart when you upgrade to this update."

There are more features and a lot of fixes that prevent issues in UR9 so go ahead and start upgrading: Update Rollup 9 for System Center 2012 R2 Data Protection Manager

Have a great Friday and a lovely weekend!

Setdpmserver, errorcode = 0x80070005, error says: access is denied

Hi,

So today I ran into an interesting problem when installing a DPM-agent on a Domain Controller in another trusted-domain.

The agent-installation completed successfully but when I ran:
   SetDpmserver.exe -dpmservername MyDPMServer.Bucatech.com
In a elevated command prompt I got received the error
   SetDpmServer failed with errorcode = 0x80070005, error says: Access is denied.

My solution, after some hours of troubleshooting, was to run a Enter-PsSession to the production server, from the DPM-server in my Bucatech.com-domain:

   Enter-PSSession ProdServer.Contoso.com -Credential Contoso\DomainAdminUser

*fill in my password in the authentication-box*

   CD 'C:\Program Files\Microsoft Data Protection Manager\DPM\bin'

   .\SetDPMServer.exe -dpmservername MyDPMServer.Bucatech.com

I hope this can help anyone of you!

What's coming for System Center in 2016?

Hi everyone,

Just a quick post to update you on what new features we can expect to see in DPM 2016:

• Protect mixed mode clusters
• New form of change tracking to replace VSS snapshot-based backups - Resilient Change Tracking (RCT)
• Storage Spaces Direct (S2D) support
• Virtual TPM support for protection of Shielded VMs

How these new features will integrate with VMM 2016 and its new "VM Checkpoint support" ("Production" checkpoints in Server 2016) is going to be very interesting!

Here is a great bloggpost covering all System Center products:

What's coming for System Center in 2016?

Microsoft recommends installing Update Rollup 8 to improve stability

Hi everyone!

Its now 2016 and we have got a whole new year of exciting new features and releases in front of us, but lets focus on our current situation for a moment.

Update Rollup 8 for DPM 2012 R2 has been out almost two months now and if you haven't already upgraded now is the time. Microsoft has received good feedback from thousands of customers and have decided to make the UR8 marked as "Important Update" on Microsoft Update. 

Here is a complete list of important issues that has been fixed since DPM UR7:

• DPM console crash issues.
• If you try to back up a SharePoint site that uses SQL Always On as a content database, SQL logs are not truncated resulting in SQL disks to become full.
• If you have multiple SharePoint farms hosted on the same SQL cluster, with different instances but the same database names, DPM cannot back up the correct SharePoint farm content.
• You try to back up Hyper-V virtual machines (VM) that have a replica and both the Active virtual machine and the Replica virtual machine are managed by the same System Center VMM server. Previously, you had no control to select between Active and Replica virtual machines for backup. This frequently caused backups to fail, depending on the setup.
• If you try to protect large number of virtual machines in a single Protection Group, and you have the VMM Helper Service enabled, some backups may fail with "System.TimeoutException".
• In some cases, alerts that are resolved in DPM are not synced in the DPM Central Console.
• If you are trying to recover data from an imported tape, DPM may crash with a "Connection to the DPM service has been lost" error.
• When you try to protect a SQL failover cluster, the Data Protection Manager UI may crash for backup or synchronization operation.
• DPM self-service recovery for SQL databases may fail with the error “Cannot connect to DPM server …”
• End User Recovery/SSRT may not work in some cases for mirrored SQL databases.
• You cannot protect a SQL database on an Availability Group (AG) if different AG have the same database name.

ID 30115: VssError: Insufficient storage available to create either the shadow copy storage file or other shadow copy data.(0x8004231F)

Hi folks,

Quick post about a small problem you may ran into from time to time!

Error Messages
You recevie the following error message in the DPM-console:

DPM failed to synchronize changes for SQL Server 2012 database SQL01\SQLIN03\DPMDB on SQL01.contoso.local 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.(0x8004231F))

And the following event is logged in the System log on the protected server:

When preparing a new volume shadow copy for volume E:, the shadow copy storage on volume C:\...\{volume-GUID} could not be located in non-critical space. Consider using a shadow copy storage volume that does not have any shadow copies. 

Cause
The Shadow Copy Service is allocated limited amount of space which is not sufficient for the creation of a snap.

Solution

• Right click the volume (in my case E:) in disk management.
• Go to the Shadow Copies-tab and located the volume (still E:) in the "Select a volume"list.
• Press settings and increase the "Maximum size:" or configure it with "No limit:"
• Press OK in the Settings-window and re run your job from the DPM-console

Update Rollup 8 for System Center 2012 R2 Data Protection Manager

Hi folks,

DPM Update Rollup 8 has been released! 
https://support.microsoft.com/en-us/kb/3086084

Unfortunately there is no new features but something worth mention is the following information:

"Note If the DPM server and protected servers are running DPM 2012 R2 Update Rollup 5 (version 4.2.1292.0) or earlier update rollups, the Agent update will require a restart of protected servers."

So what does this mean? Well, are you running UR6 and UR7 DPM-agents in your enviroment. There is no need for restart when you update them to UR8!

Below is the Issues that are fixed in this update rollup:

• The DPM Agent crashes intermittently during a backup.
• If you are trying to recover data from an imported tape, DPM may crash with a "Connection to the DPM service has been lost" error.
• If you try to back up a SharePoint site that uses SQL Always On as a content database, SQL logs are not truncated as expected.
• You cannot verify tape library compatibility for tapes that use RSMCompatmode settings such as IBM 35xx, 2900, and so on.
• If you have multiple SharePoint farms hosted on the same SQL cluster with different instances but the same database names, DPM cannot back up the correct SharePoint farm content.
• If you run Update Rollup 7 for Data Protection Manager 2012 R2, and you have already configured online protection for one or more protection groups, trying to change the protection group populates the default DPM settings for the "Select long-term goals" wizard instead of the previous configured values.
• When you try to protect a SQL failover cluster, the Data Protection Manager UI crashes for every backup or synchronization operation.
• If you install Update Rollup 7 for Data Protection Manager 2012 R2, self-service recovery for SQL databases may not work, and you receive the following error message:

Event ID 10028: DCOM was unable to communicate with the computer...

Hi,

A small post regarding my solution to a problem I encountered today.

Issue:

Backup-jobs have been failing and your DPM-agent is listed as unavalible.

In the Event Viewer on your DPM-server event id 10028 is logged in the System log:

DCOM was unable to communicate with the computer contoso-app01.contoso.local using any of the configured protocols; requested by PID a24 (C:\Program Files\Microsoft System Center 2012\DPM\DPM\bin\msdpm.exe

The first thing you would troubleshoot is if there are any firewalls that are blocking the communication but for my case I knew nothing had change in the communication.

Resolution

1. Open up an elevated command promt and run ipconfig /flushdns.

2. Refresh your agent on the Management-tab in your DPM-console.

3. Re-run any failed DPM-jobs.

A very simple solution in my case to get the jobs working again but there is still some work to find out if there is an issue in the DNS registration in Active Directory.

Take care!
