DPM 2012 R2: over W2008 o W2012 server?

Hi, I have a simply question:
With DPM 2012 R2, is recommended to migrate to windows 2012? Out actual plataform is W2008 R2 updated but we dont know if a W2012 plataform can bring improvements with performance or similars...
Regards & thanks.

Hi,
There is no real need migrate to Windows server 2012 unless you need DPM to protect data sources like Windows server 2012 Dedup volumes that would require DPM to be running on a Windows 2012 server in order to protect it.

Moving the DPM 2012 SQL Database to another SQL Server

I have 2 DPM Servers running and I would like to move those SQL Dbs onto another SQL Server. I know during the install you can select whether or not you want to install SQL or use another instance, but I dont want to re-install the whole thing and start
over. Is there any easy way to do this?

Hi,
in my opinion, you can stop with this Walkthrough after step 6, dont think that you Need to do a sync or consistency check.

DPM 2012 Backing up a VM on Server 2012 Hyper-V CSV Host - Not Working with Hardware VSS

Hi All,
I'm trying to backup a VM on a 2012 Cluster. I can do it by using the system VSS provider, but when I try to use the hardware provider, (Dell equalogic) it doesn't work. DPM will sit for a while trying and then report a retryable VSS error.
The only error I'm seeing on the Host is the following:
Event ID 12297Volume Shadow Copy Service error: The I/O writes cannot be flushed during the shadow copy creation period on volume \\?\Volume{3312155e-569a-42f3-ab3a-baff892a2681}\. The volume index in the shadow copy set is 0. Error details: Open[0x00000000, The operation completed successfully.
], Flush[0x80042313, The shadow copy provider timed out while flushing data to the volume being shadow copied. This is probably due to excessive activity on the volume. Try again later when the volume is not being used so heavily.
], Release[0x00000000, The operation completed successfully.
], OnRun[0x00000000, The operation completed successfully.
Operation:
Executing Asynchronous Operation
Context:
Current State: DoSnapshotSet
I don't know where to go from here - There is no activity on the CSV (this is the only VM on it, and both the CSV and VM were created specifically for testing this issue
Does anyone have any ideas? I'm desperate.
Update:
Ok, so I can Take DPM out of the picture. Trying to do a snapshot from the Dell Auto-Snapshot manager, I get the same errors. But I also get a bit more information:

I had a similar issue with an environment that had previously been working with the Dell HIT configured correctly. As we added a third node to the cluster I began seeing this problem.
In my case I had the HIT volume max sessions per volume at 6 and maximum sessions per volume slice set to 2 and the CSV was using a LUN/Volume on the SAN that was split across 2 members.
When the backup takes place and Dell HIT is configured to use SAN snapshots the vss-control iSCSI target is used which in my case exceeded my limits for maximum connections per volume as I'm using 2 paths per Hyper-V node with MPIO (this is my
current theory).
Once I'd modified these settings I could then back up the VHD's on that CSV again.
Hope this helps.

DPM 2012 R2 protecting a SQL 2008 Cluster/Vss Writer problems on SQL Server

Hola,
I am running DPM 2012 R2 rollup 4. My Server OS is 2012 Datacenter. I have a SQL 2008 Active/Passive cluster and MS support has kicked this to the SQL team for review. OK hear we go ..When I run the vssadmin list writer I do see the SQL Writer. Also
says no errors. When I run diskshadow /l c:a.txt from an admin command prompt the output does show the SQL Writer information but under that should display all the meta data for each connection to the database so DPM can expand the SQL database to
be chosen for protection. I am already confused.
I am going to include a snippet from the vssadmin and the diskshadow command:
vssadmin list writers:
Writer name: 'SqlServerWriter'
   Writer Id: {a65faa63-5ea8-4ebc-9dbd-a0c4db26912a}
   Writer Instance Id: {8d773b6f-0196-4c34-9943-f258f99c2d9a}
   State: [1] Stable
   Last error: No error
Diskshadow /l c:a.txt
* WRITER "SqlServerWriter"
  - Writer ID   = {a65faa63-5ea8-4ebc-9dbd-a0c4db26912a}
  - Writer instance ID = {8d773b6f-0196-4c34-9943-f258f99c2d9a}
  - Supports restore events = TRUE
  - Writer restore conditions = VSS_WRE_ALWAYS
  - Restore method = VSS_RME_RESTORE_IF_CAN_REPLACE
  - Requires reboot after restore = FALSE
  - Excluded files:
* WRITER "BITS Writer"
  - Writer ID   = {4969d978-be47-48b0-b100-f328f07ac1e0}
  - Writer instance ID = {5ad5c4f7-5f68-4c1d-a4fc-92d5ef898881}
  - Supports restore events = TRUE
  - Writer restore conditions = VSS_WRE_UNDEFINED
  - Restore method = VSS_RME_UNDEFINED
  - Requires reboot after restore = FALSE
  - Excluded files:
   - Exclude: Path = C:\Windows\System32, Filespec = bits.log
   - Exclude: Path = C:\Windows\System32, Filespec = bits.bak
   - Exclude: Path = C:\ProgramData\Microsoft\Net
As you can see this did not return the expected results. I should see the meta data for each database. This is why DPM can't list the databases for backup in my 2008 production SQL cluster. Any thoughts? This has not been working for quite sometime. I was
hoping the update to rollup 4 would have fixed the problem. I know this is a SQL problem but has anyone had this experience?
Thanks
Steve J.

Update:
Uninstalled SQL Server instance and downloaded SQL Server 2012 SP1 image from link in error message. It takes you to the download page for the express edition of SQL Server 2012. I downloaded the SQLEXPRADV_x64_ENU file and used it to re-install
the SQL Server instance.
Ultimately I had to use the ISO image to upgrade the instance to Standard because the SQL Server Agent will not run under the express edition and caused the DPM install to fail.
The DPM installation then completed successfully and after immediately went to Windows Update and SQL Server 2012 SP2 was installed.
Evidently you cannot start with SP2 until the installation is complete.

Can DPM 2012 R2 backup SQL Server 2012 AlwaysOn enabled databases

Is it possible to use DPM 2012 R2 for backing up
SQL Server 2012 AlwaysOn enabled databases ?
Because if Alwayson configured for any Database , particular database is not available to select for backup.

Hi,
Yes, starting with DPM 2012 SP1 SQL AlwaysOn enabled databases can be protected as long as they are not part of sharepoint farm. DPM shows the Availability Groups under Cluster Group.
You must explicitly add the system account NTAuthority\System or NT AUTHORITY\DPMRA to the Sysadmin group on SQL Server.

DPM 2012 - Get unprotected Clients via Powershell

Hey,
i want to get all unprotected Clients via Powershell (or SQL). In the DPM 2012 Console over the Management View it's easy to see, but i cannot find a cmdlet, so i want to create a Report about unprotected Clients.
Thanks in advance! :)

Ok. Ensure that where you execute the script you have the AD Powershell Module and use this script:
Import-Module ActiveDirectory
$computers = Get-ADComputer -Filter *
foreach ($computer in $computers){
$computerName = $computer.DNSHostName
$object = Get-WmiObject -ComputerName $computerName win32_service -filter "name='DPMRA'"
if ($object -eq $null){
Write-Host -ForegroundColor Red "The server $computerName has no DPM agent installed"
} else {
Write-Host -ForegroundColor Green "The server $computerName has the DPM agent installed"
You can improve it with log, etc... Tell me if it works :-)

DPM 2012 setup to remote SQL 2012. SSL cert error

First of all, the category I selected, which was for SQL server reporting services was as close as I could get. There wasn't a way to select System Center DPM server from the list. As this relates to the Report Server portion of the setup, I chose this category.
I am setting up DPM 2012 SP1 on a single use server (Windows Server 2102 R2 Standard) and remotely connecting to a new DB server (MSSQL 2012). I keep getting error ID:812 when trying to install, and the logs show that it is trying to set up report server,
but that it cannot establish a trust relationship for SSL/TLS.
* Exception : => System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS
secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.
I'm not clear on how to proceed. Invalid cert means it wants something very specific.
I have installed a domain issued cert from the DC on the SQL reporting server and have bound that cert to SSL using report server configuration. I then imported the cert into the DPM server in the trusted and personal certs. The DPM server has our DC as
a trusted source. That clearly doesn't work.
Thinking I may not be able to use a self-signed cert, I then installed our wildcard cert onto both the SQL server and the DPM server. I ran through the Report Server configuration again and bound that wildcard. This is a Godaddy wildcard cert.
Same problem no matter what I do. Clearly, this is matter of a cert issue, but I'm lost. There are zero instructions I've found on how to ensure Windows server 2012 cert requirements are met as it relates to SQL and DPM.
Thanks for your advice.
Kaden

Hi Kaden,
This thread is for reporting service and I hope i can provide some useful informaiton from reporting service side while i don't work on DPM at all. You may still need to find out the forum for the DPM and check there.
Regardingless of DPM, Reporting Service can usually create HTTP link and HTTPS link together. For the HTTP one, a certificate is needed. HTTPS is not needed excep you have the concern with security.
Usually application like DPM/SCOM will connect to the web service link provided by Reporting Service and work on that.
If the application requires a HTTPS link, then same thing has to be setup on reporting.
You need to install a certificate and add it to trust store and then configure reporting service to listening on HTTPs 443 port from the reporting service configuration manager.
You can find the steps here.http://technet.microsoft.com/en-us/library/ms345223(v=sql.110).aspx
After you create the HTTPS link successful, try to open the https web service link both remotely or locally from IE. If you can open it there without any error, reporting service is working fine.
For some applications, they would need special certificates installed on reporting service and used. You may check with the related product on this then.
In a summary, if you can configure a HTTPS link for reporting service can open it correctly, configuration steps on reporting service is fine.
If there is still any error from DPM, you would need check additional resource from DPM part.
Thanks,

DPM 2012 R2 fails to back up one of two disks on file server

Good day! I've built a new DPM 2012 R2 server and migrated or re-created jobs from my older 2012 SP1
DPM servers as trying to upgrade them was not working out. The DPM R2 server is running great besides this one issue. The problem is with a file and print server at a remote office. Since it has around 750 GB of user data on it I chose to do manual replica
creation on the data disk, (E:) but created the C:\ drive replica normally, over the WAN. The manual replica creation was successful, and the initial consistency check and recovery point creation worked as expected, however, since then it will not create another
RP or run a CC on the E:\ drive. Recovery points on the C:\ drive are being created properly. When I try to run a CC I get this error: "An unexpected error occurred while the job was running. (ID 104 Details: Access is denied (0x80070005))" I've
tried to drop protection on the two directories of the E:\ drive (retaining data) and re-create, but that didn't help. I've even done a recovery from the initial RP to verify that it was created properly, and that worked as well.

Open command prompt on target file and print server, change directory to
C:\Program Files\Microsoft Data Protection Manager\DPM\Temp> and run below command
C:\Program Files\Microsoft Data Protection Manager\DPM\Temp>find /i "[0x80070005]"

How to backup Hyper-V host server on DPM 2012 R2

Hi,
I'm about to backup my first Hyper-V host server using DPM 2012. I'm looking for a strategy to back up both the host server and virtual machines. Note: I'm not really interested in backing up all the virtual machines. Many are non-production
or for testing. How do you do it? I was thinking about selecting in the protection group:
- BMR and SS for the Hyper-V host
- The C: volume of the Hyper-V host
- Select the Child partition snapshots of the virtual machines I want to backup.
In my environment, Hyper-V role is installed on the C: drive, but the virtual machines are stored on E:, which I would not backup directly (volumes) since I'm backing up the VMs using Child partition snapshot.
Would I be able to restore my Hyper-V host and the selected VMs with a backup like this?
Anyone want to share how they setup their protection groups for Hyper-V?
Thanks.

No, use full server backup (image) if VM config are stored at default storage (disk C).
Understanding where your virtual machine files are [Hyper-V]
Using this method to perform a full server backup is the recommended method because it captures more data than the other method.

DPM 2012 R2 Rollup 4, Update Rollup 7 for Exchange Server 2010 SP3 backups with eseutil check fail

Hi,
It could be a coincidence, but ever since installing Update rollup 4 onto DPM 2012 R2, (which was at UR3 I believe) I haven't been able to complete an Exchange express full backup or consistency check with verification using Eseutil checked. If I have the
eseutil check enabled I get the following error:
Type: Consistency check
Status: Failed
Description: Data consistency verification check failed for LOGS of Exchange Mailbox Database Mailbox Database 2011112513 on SERVER.xxx. (ID 30146 Details: The process cannot access the file because it is being used by another process (0x80070020))
Disabling the eseutil verification allows it to succeed, but I'm not happy to continue with that for too long.
I've had this running for many years and this is the first real issue with exchange, its a single stand alone exchange database.
Any ideas?
Thanks,
Andreas

Andreas,
the error is stating that something else has a handle to a file or files during the ESEUtil check. Typically this is AV. I have also seen where the Exchange limits are exceeded and that causes the issue.
Please ensure you have the DPM AV exclusions for the DPM server and I would advise the DPMRA.exe on the PS. You can also trying disabling or removing AV as a test.
DPM AV exclusions -
http://technet.microsoft.com/en-us/library/hh757911.aspx
You may also want to test using eseutil against the logs outside DPM and see if that fails with similar issue. Let us know. Thanks

DPM 2012 R2 Reporting Server locations

I' m just looking to see what is and what is and not supported for a DPM 2012 R2 Topology for the SSRS.
When using multiple DPM servers with SSRS installed locally on the DPM server. Does each SSRS instance need a separate ReportServerDB on a remote SQL server running the SQL DB Engine. Or can they report to the 1 ReportServer DB on the remote SQL server?
I know I can have each SSRS instance installed on each DPM server point to the same SQL Server but creating multiple ReportServer databases.
Thanks

Hi,
Single DPM server with SQL installed locally = SSRS is used locally.
Multiple DPM servers sharing a remote SQL server instance = SSRS will also be shared in same SQL instance.
Multiple DPM Servers sharing a clustered SQL Server instance = SSRS will need to be on separate non-clustered SQL Server. For each DPM server using the same standalone SQL Server instance - the SSRS will be shared.

Upgrading DPM 2012 SP1 to DPM 2012 R2 fails (DPM Setup is unable to connect to the specific instance of SQL Server Reporting Service (ID: 33431)

The Background:
1. DPM 2012 SP1 was originally installed on a server with local SQL 2008 R2 instance (SQL was installed as part of DPM)
2. SQL database was upgraded to SQL 2012 SP1

DPM 2012 R2 crashes during tape backup for a specific server

The server is part of a protection group that is co-located, I am trying the backup not as part of a co-located set to see if this makes any difference.
Tape backups for other servers, which are part of the same co-location group, work fine and it seems to be just this one causing the issue.
I have seen a few other posts on the net referencing "WARNING MediaPool 00000000-0000-0000-0000-000000000000 does not exist." where people have similar issue with DPM crashing out but so far nobody seems to have any answers.
I am debating removing the protection group and trying to 'start from scratch' but wondered if anyone else had any thoughts ?
Thanks in advance,
Ed

Hi,
Open SQL management studio and connect to the instance used by DPM.
Run the following Query against the DPMDB and see if it returns any rows, if so please provide the output.
select MP.mediapoolid, MP.PGSETID from dbo.tbl_MM_MediaPool MP
Join dbo.tbl_IM_ProtectedGroup PG on PG.ProtectedGroupId = MP.MediaPoolId
where PG.MediapoolId is NULL
and MP.PGSetId is not NULL

Does DPM 2012 R2 still needs DataSourceGroups.xml and MaxAllowedParallelBackups key when using Hyper-V VSS Software Writer to backup Server 2012 R2 Cluster

Hi,
Does DPM 2012 R2 still needs DataSourceGroups.xml and MaxAllowedParallelBackups key when using Hyper-V VSS Software Writer to backup Server 2012 R2 Hyper-V Cluster with CSV's? Can't find a clear answer somewhere.
Thanx for helping me out.
DJITS.

Configure CSV backups
If you are running Hyper-V on Windows Server 2008 R2 and you’re backing up multiple clusters with DPM, you need to ensure that only one backup uses the same CSV at any one time. To do this, follow the instructions in
Serialize virtual machine backups.
If you’re using software VSS with Hyper-V on Windows Server 2008 R2, do the following
Serialize virtual machine backups per node
Serialize virtual machine backups per CSV LUN
Have a nice day !!!

DPM 2012 R2: over W2008 o W2012 server?
