DPM could not enumerate SQL Server instances using Windows Management Instrumentation

October 27, 2010, 12:57 am

Hi

I have a problem with a SQL 2008 Server in DPM.
When I create a new Protection Group and browse the SQL Server I receive the Error "DPM could not enumerate SQL Server instances using Windows Management Instrumentation on the protected computer SRV-SQL-001.test.local (ID: 965)"

On the SQL Server in the DPMRACurr.Errlog File are the following entries:

 WARNING Failed: Hr: = [0x8004100e] : unable to connect to the wmi namespace: root\Microsoft\SqlServer\ComputerManagement
wmiqueryhelper.cpp(158) [000000000344EFB8]  WARNING Failed: Hr: = [0x80041010] : unable to execute the WQL query: SELECT * FROM ServerSettings
sqlmirroringhelper.cpp(159) [000000000344F558]  WARNING Failed: Hr: = [0x80041010] : F: lVal : wmiQueryHelper.ExecuteWQLQuery(ssWMIQuery)
sqlmirroringhelper.cpp(75) [000000000344F558]  WARNING Failed: Hr: = [0x80041010] : u: lVal : GetInstanceNamesFromWMI(ssWMINamespace, arrLocalInstanceNames)
neapplicationnamespace.cpp(1582) [0000000000393890]  WARNING Failed: Hr: = [0x80041010] Failed to query SQL instancess from WMI

The WMI Namespace root\Microsoft\SqlServer\ComputerManagement does not exist on the SQl Server. But I think this in normal because the correct namespace for SQL 2008 should be root\Microsoft\SqlServer\ComputerManagement10

It seems like the DPM Agent recognizes the SQL 2008 Server as a SQL 2005.

Because of this error the autoprotection of new Databases doesn't work. How can I fix this error?

Thx

Hi All,
We use DPM 2012 since 2 year ago for MSSQL servers backups, We have implemented the self service and all configuration were done successfully and usage is very easy for ours customers.

Recently we have notice an issue.
Our Protection groups were set to sych each hour, when a customer use self service and restore a DB and he doing the restore operation just before the DPM sychronisation (hourly) the restore is done successfully but the scheduled DPM task will never start, we have to wait to the next hour for DPM sych all Databases,
Can you imagine if another customer start another restore DPM will miss two hours of DPM sych and ... and ... and ...
Hope I'm enought clear in my description.

Someone have any idea?

Hello everyone,

I was wondering if it was possible to backup an entire VM running a couple of Oracle DB's (version 11 or 12)?

My system:

DPM server: Windows 2008R2 Enterprise

Hyper-V host: Windows 2012R2 Standard

VM: Windows 2008R2 Enterprise (has the oracle DB's )

Or what other backup options do I have using DPM 2012?

DB's cannot be stopped they are in a production environment. Thanks.

Cannot re-add SQL database to protection group

Hello,

I have a situation where my BES database was inconsistent in DPM 2012 SP1. I removed the DB from my SQL protect group and deleted the replica data from the server. When I try to re-add it back to the protection group, I am unable to see the DB in the list of DBs on the instance.

  • BES DB is mirrored (no FS Witness)
  • Principal is 2008 R2 SP1 Cluster
  • Mirror is 2008 R2 SP1 Server (No Cluster)
  • DPM Server is DPM 2012 SP1, version 4.1.3417.0
  • Protection Group is Auto-Protection enabled

I have stopped protection on the entire SQL Cluster (keeping data), recreating the Protection Group. I have also disabled and re-enabled Auto-Protection. No dice.

Any ideas?

DPM SQL Protection of Multiple Instances on one Host

February 18, 2013, 2:00 am

Hello

We have a single DPM 2010 Server instance (with Agent version 3.0.8195.0) and we are trying to protect databases on three SQL Server 2008 R2 x64 SP1 instances, which live on the same server.

The instances all listen on the same port, but on different IP addresses allocated to the same server. No instance listens on the default IP of the server. No instance listens on the localhost IP.

When enumerating the SQL data sources on the DPM server (e.g. when creating a new Protection Group), we can see the details for one of the three instances but the other two instances error out (after a very long time).

The errors shown for the two instances are:
For each Database: DPM could not enumerate the application component <SQL DB> on <PS> ID 964. Please mae sure that the writer is in good state.
For the instance: DPM could not connect to SQL Server instance <Instance> on the <PS> ID 966. Please make sure that SQL server instance is in good state.

I can confirm that:
1. Communication between DPM and the protected server seems fine
2. The SQL Server VSS writer is not in an error or inconsistent state (with "vssadmin list writers")
3. The "NT Authority\Local System" account has SysAdmin SQL permissions for all instances
4. The SQLServerVSSWriter service uses the "Local System" account
5. The backups for the instance that does work is fine and running stable
6. There are no known issues with the two instances. They are running, in production and we have not come across any issues when connecting to them in SSMS or otherwise

For the two instances that don't work, I have run the SQL Profiler when DPM was querying these instances. I can see the DPM Agent log on to the instance, retrieve the list of databases with:
select name,  recovery_model_desc, state_desc, CONVERT(integer, is_in_standby), ISNULL(source_database_id,0) from master.sys.databases

and query the databases with :
select rtrim(physical_name),rtrim(type_desc),rtrim(state_desc), is_name_reserved from sys.master_files where DB_ID(N'master') = database_id

But there is no futher communication.

Does anyone have any idea on why DPM can't enumerate the SQL databases on the two instances when the DPM Agent appears to be able to log on and have access to the SQL instance?

Thanks

DB Recovery fails with "The protection agent on DPM1.xxxxx was temporarily unable to respond because it was in an unexpected state. (ID 60 Details: Internal error code: 0x809909B0)"

The protection agent on DPM1.rdc-uk1.local was temporarily unable to respond because it was in an unexpected state. (ID 60 Details: Internal error code: 0x809909B0)

This error occurs regardless of type of restore (to DB or network folder) Other DBs of essentially the same data backed up via other servers recover without a problem.

The DPMRA on the DPM server appears to be crashing after about 1-2 minutes of starting the recovery. No data is restored.

The replica and recovery points on the server seem to be being created normally.

If anyone has a pointer on how I can go about diagnosing the root of this issue I'd be grateful.

Regards

dpm 2010 v3.0.8195

I'm trying to add a database to a protection group that already includes all databases on a sql instance.  The SQL instance is sql 2005 on windows 2008 r2.  The database is compatibility level 80. 

When I try to modify the PG all the other databases are listed and checked(auto protected), but I can't see the new database. Nor is it automatically added.

Has anyone seen this behavior?

I am backing up a 2012 fileserver Cluster and every weekend I get this tracking information is corrupt notification, which is followed by a consistency check which resolves it (15 minutes later). 

DPM is unable to continue protection for E:\ on fs.STORAGEGWCL1.xxx.xx because the change tracking information is corrupt (ID 30156 Details: The process cannot access the file because it is being used by another process (0x80070020))

Has anyone run into this?  I am running DPM 2012 R2, and the cluster is also running 2012 R2.

Protecting WSUS DB (WID) with DPM 2012 SP1

Hi,

trying to configure protection of our WSUS server that is built on Windows Server 2012, were using WID as back-end for this particular installation and for some reason I'm unable to set up protection from DPM 2012 SP1 - database simply does not appear on the list of objects available for backup only network shares and system state are listed. So far we've reinstalled DPM agent, installed UR5 for DPM 2012 SP1 and updates all agents, addedNTAuthority\System to the Sysadmin group but still no joy.

Any ideas?

Cheers

Hello,

I am in the process of trying to recover some databases to an alternate location.  The process goes fine until the Specify Alternate Recovery Destination screen.  When I try to expand the servername, it takes about 10 minutes to populate, after which I see the Volumes and Shares.  Is there any tweaks I need to do to my setup to have it remember locations?

SQL Best Practices

We are currently backing up all our databases to Azure and that seems to be working very well. My question is, should I also be backing up the server volumes to Azure as well?

If so, should we back the volumes up at the same schedule as the databases or once a week? I also have the option of backing up to tape as well.

Thanks for the insight.

Move change the master Protection Server

I have a 3 SQL servers(2008 R2 SP2 Enterprise) on a four node Cluster (2008 R2 SP1 Enterprise)

These are protected by two DPM Servers 1 and 2.

DPM2 was the master protection server, backing up all databases all servers and also backing DPM1 system state, BMR and DPM SQL Server, plus all volumes as well.

DPM1 provides protection for all Protection groups on DP2 and also backing DPM2 system state, BMR and DPM SQL Server, plus all volumes as well.

DPM1 is Local to SQL Servers

DPM2 is on the end of a WAN.

I want to switch back to DPM1 and relieve stress on the WAN.

So....

  • I removed all protection groups from DPM2 deleting all the data.
  • I detached all nodes from DPM2
  • I ran setdpmserver on each cluster node and attched them to DPM1
  • I created new protection groups on DPM1 for databases.

This is were the problems started with (unable to create recovery point) and when creating PG's I had error messages about these items are protected by anther server.

does anybody know the correct procedure for doing this ?

DPM backup with SQL FCI and Availability groups

June 24, 2013, 1:56 am
$

Ok im currently using an availability group on top of a SQL failover cluster and im having trouble getting DPM to work this setup.

When i create my protection group i can find my AG wrapper name under the failover cluster instance group but i see this is the windows cluster service but doesnt include any databases below.  The only place i can find the relevant database is looking under the sql cluster instance and the database appears i can tick this and proceed.  The problem comes when im running a consistency check, when this is run it says "DPM failed the current backup because the previously standalone SQL database is now part of a SQL Availability Group."

I think DPM cant handle the availability group on top of the failover cluster instance.

We are currently running SC DPM 2012 SP1.

Anyone come across a resolve to this?

Thanks

Is there a document that explains what all the DPM services and executables do?  I'm trying to determining what would cause performance issues - whether it's a primary backing up a protected server, a secondary backing up the primary, DPM doing house cleaning, contention if both primary and secondary backups are occurring at the same time, etc.

Advantages and disadvantages with DPM regarding SQL Server

I have some questions regarding DPM for SQL Server.

  1. Does anyone know how DPM (Data protection management) in System Center works with SQL Server (how does it backup data)?
  2. What are the advantages/disadvantages of DPM?
  3. Does it mirror or replicate a SQL Server database?
  4. Why/why not should one chose DPM for SQL Server?
  5. I've read somewhere that it isn't a single point of failure, could someone explain that further?
  6. What is the difference between DPM and AlwaysOn Availability Groups regarding disaster recovery and when one wants to achieve zero data loss?

Would be thankful if someone could help me!
