Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Files system backups are fine but Exchange Backup is failing. 

bpbkar log on client stops with following last message always:

"Active Directory Application Mode"

When we try to browse the Backup Selection on Exchange policy, Information store is not shown at all. 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

bpbkar log from client with enhanced verbose debug level. 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

@AB_Chaudhry 

Have you tried to check Application log on the Exchange server for errors?
Or checked for Service logon that may need to be changed or expired password?

With literally everything in this environment no longer supported from Microsoft or Veritas, you are going to battle to find support.

Any chance that the environment can be upgraded/migrated to supported OS, Exchange and NBU?

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Please, share your client's application and system event logs (in text format). 

 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Hi Mike,

Please elaborate:

Client's Application => Netbackup client log or Exchange logs from client ?

We did not find any event in system event logs related to Application or Application Error. BPBKAR is crashing and we did not observe any event. Please guide if we can some how force NB Client to generate event. 

Thanks. 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Hi Marianne, 

We are already suffering without support so I posted it here to get some experts opinion. We are planning to upgrade and migrate but for that purpose backup is even more important now.

We did not see any Application events in Event viewer. How can we verify Service Logon? any technote to refere. 

It looks like NB Client is unable to talk to Exchange to get the data set TAR file created for backup. BPBKAR crashes just before it created the TAR for backup. Secondly, in the policy when we browse for storage groups and information store, it shows nothing, just the exchange server name. 

Thanks. 

 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Good thing that you noticed bpbkar crashing on the client.

If you can locate your 7.6.0.1 software, then please upgrade the client software.

 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

We tried upgrade and reinstallation of client on second node of exchange cluster but "Socket error 13" remains same. Only difference was that we could observe BPBKAR crash event logged on this node:

Faulting application bpbkar32.exe, version 7.1.2011.203, time stamp 0x4d4b1fda, faulting module MSVCR80.dll, version 8.0.50727.6195, time stamp 0x4dcdd833, exception code 0xc0000005, fault offset 0x000000000001e38c, process id 0x3d4,
application start time 0x01d6925e67c54c7e.

We verified the library MSVCR80.dll on both nodes and other working clusters. It was leading us to other errors but the situation was same, bpbkar was crashing exactly after 10-13 minutes of "Begin writing" where it should create the TAR to write. so we failed over to the node where old client was available. These clients and configurations were working fine a week before. There is no update, patching or configuration changes in NetBackup. 

Since the socket failure error was appearing after exactly 10 minutes so we changed and doubled  timeout values also but no success. 

Thanks. 

 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Hi Marianne,

We can update NB Client to 7.6 to test it but did it support Exchange 2007  on Windoes Server 2008 R2?

Thanks. 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Yes. I have checked -  7.6.x supports this combination.

Please upgrade the client.

If bpbkar is crashing, then bpbkar log is not going to help at all.

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Thanks Marianne, Really appreciated your quick response. 

We will try upgrade and test. 

Do we have any way to test connection between NB Client and Exchange ? We want to verify that there is no libraries, permissions or authorization issues on client and application by passing Master Server, Network and Policies. 

Regards. 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

The filesystem backups are working fine with same client and we have issues with only Exchange backup which was also working fine one week before. So we suspect some connection issues betweek NB Client and Exchange. 

Regards. 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Top question: Has this ever worked? If yes, what changed?

Before NetBackup 7.6, you needed to execute 3 services on the client as a domain admin:

- NetBackup Client Service
- NetBackup Legacy Client Service
- NetBackup Legacy Network Service

7.6 introduced the option to run these services as LocalSystem and configure the Exchange credentials in the client host properties. (Beginning with Exchange 2013, you must configure the credentials in the client host properties.)

If you can't browse for the backup selections in the policy, how are you setting them? What is your backup selection?

With Exchange 2007, you could do snapshot backups, or you could use the Exchange streaming backup feature. Which are you doing?

When you say you have Exchange 2007 cluster, which flavor of cluster is it? I vaguely remember letters like CCR and LCR.

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Hi Marianne,

we have updated NB Client to 7.6 and tried again and faced same problem. BPBKAR, BPBRM, Job details and even log is attached. 

Thanks. 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Hi Lowell,

We have successfully installed NB Client 7.6 and tested successful file system backup. We are facing problem with Exchange backup only. 

The services are running as LocalSystem and no credentials in Exchange credentials in client host properties. This was working fine with this cluster and similar configurations are working with another cluster. 

We used to browse and selected storage groups and they are still in the policy in backup selection but if we try to browse it now, we see nothing except the name of the exchange. 

It is snapshot backup and CCR Cluster. 

Suggestions will be appreciated. 

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

How can we see and log the activity of NB Client connections in Exchange Cluster logs ? any ideas?

Any changes on Exchange cluster may impact backups ?

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

You need to change logon account and Host Properties or registry settings after the upgrade. Like you do with a new config.
The NBU 7.6 for Exchange manual has a section for Exch2007. Please go through this section and carefully check all requirements on Exchange and NBU side.
Sorry that I cannot share more info - I no longer have any pre-8.x manuals.

Re: Exchange 2007 cluster backup on Windows 2008 R2 is failing. Error 13

Exchange CCR was just Exchange 2007 on two Windows servers replicating their data to each other. As far as NetBackup connections were concerned, they were two distinct clients. You should find logs on both Exchange servers.

For CCR, one server was active and the other passive. Exchange could fail over from one server to the other. In later Exchange versions individual databases have an active copy on one server and passive copies on zero or more other servers.

NetBackup snapshot Exchange backups involve two process, bpfis.exe for the snapshot and bpbkar32.exe to back up the snapshot to the media server. CCR added a complication if the policy was configured to back up the passive copy. Bpbrm would start bpfis on the active CCR node. Bpfis would detect that it should be running on the other node and return to bpbrm, which would then execute bpfis on the passive node. (There was a bug in that dance move at one point. I think I fixed it in 7.6.0.x, but I don't remember x.)

That's my next point. NetBackup releases through 7.6 had companion maintenance releases. Even when leaving the master server on the GA release, you should always have installed the highest triple-dot maintenance release on the clients (7.1.0.4, 7.5.0.7, 7.6.0.4). This gets you lots of fixes, and in the case of 7.6.0.3 and later you get an upgrade to the BEDS backend database agents.

And yes, you should configure Exchange credentials in 7.6 even if you hadn't done so previously.

It would be easier to give more specific answers if you were on a supported version of NetBackup. NetBackup support for Exchange 2007 ran until version 8.1.
