Failing Exchange 2007 Backup with NMM

Hello keithb1984

Can you change the NSR_ALT_PATH=D:\mnt for example? Just try to avoid a root FS folder for that value.

Is this stand-alone Exchange server? If not please let us know what kind of setup are you running.

If it still fails after this change please provide:

nmm.raw file from Exchange server (/nsr/applogs/nmm.raw)

and

Screenshot of all tabs from the configurations of client and group.

Thank you,

Carlos

Hi Carlos Rojas,

Thank you for your help with this! I took your advice and changed the path to NSR_ALT_PATH=D:\mnt  which seemed to get me further int he backup process but again it failed and the current failure message is:

savegrp: suppressed 3 lines of verbose output

I attached the nmm.raw file from the Exchange server.

Client Config Screen Shots:

Can you check the status of Exchange writer and check the availability of Data port & control port.  Sometimes, Both ports might be occupied by other application.

Hi,

Please remove the directive set for the client (NT with compression), as directives are not supported.

On the other hand I would strongly recommend you to upgrade NMC to the same version as NW server, as you are missing some functionalities and configurations only available from NW 8.1.x

Anyway I see a configuration issue. There is a host name in the logs (client starting with oa***). What is the relationship of that client with the actual Exchange client? I suspect a wrong alias configuration.

What Exchange topology do you have in place, stand-alone, LCR, SCC, CCR?

If clustered environment, you need to create a client entry for all the physical nodes, but based on the logs I suspect this is stand-alone Exchange server, right?

Ohhh, I just saw that NW server is 7.6, not only NMC,  but NW server itself:

NetWorker Server Version: NetWorker 7.6.5.0.Build.1160 Network Edition/20

This is supported, but I would encourage you to upgrade NW server to 8..1.x

On the other hand, finally this is a configuration issue, that client I just mention is not configured properly:

exch**** nsrsnap_vss_save NSR critical NMM .. The rollover failed with error 'Backup failed while creating coversave. client `oa******' is not properly configured on the NetWorker Server. Please make sure you have configured at least one NetWorker Device and client resources are configured for the application host [Exch**] and the Mount Host [exch***] on NetWorker Server [ar******]'.  Refer to the PowerSnap logs for more information.

Thank you,

Carlos

Group Config Screen Shots as Requested:

I will certainly look into the version upgrade you suggested and try to get that  deployed ASAP.

I have also removed the ‘NT with compression’ directive.

The oa*** is the Exchange Offline Address Book record. I don’t think I understand what configuration needs to be in place for that... I didn’t setup this Exchange server so I apologize that my knowledge of it is a bit weak.

You are correct that this is a stand-alone server.

Thanks again for all of your help!

Hi Carlos Rojas,

We do have DNS records configured on our Domain Controller that point to the same IP for the oa***, Exch*** and active***.

Each backup attempt take about 30 minutes before it fails so I will update this once I have made the alias field changes and attempted the backup again. I started another backup attempt after removing the compress directive so I want to wait this one out then I will make the changes and try again.

again... thank you thank you thank you thank you

Hey Keith,

Happy to hear it worked for you.

Please mark the question as answered if you feel like it

By the way, for you and any other ECN community member interested, I'm running an "Ask the Expert" event about NMM configuration, best practices and troubleshooting, and will run until the 21st of September (one in English and another one in Spanish), so if you are interested please use the links below to join:

Carlos Rojas,

Let me just tell you that you are the man! My backup just completed and it truncated my Exchange logs!

For anyone who may stumble across this forum the configuration changes I made during the process where to remove the Backup Directive for 'NT with compression directives, changed the "NSR_ALT_PATH=" from just the root of D:\ to a subfolder (D:\mnt), and maybe most importantly was adding the Aliases for all of the DNS records for the exchang server IP which include activesync and oab DNS records.

Thanks again!
