Scheduled backup fails and Manual backup succeeds

Hi

Im running NetWorker version 7.5.2 on Windows 2008 R2 NetWorker server.

I recently just uninstalled 7.5.2 on 2 of my Windows 2008 clients to install 7.5.1.10 to fix the VSS backup issue.

after installing this version my schedule backups do not want to run, However the Manual backup succeeds when I run it from the client.

i then went backup and installed the 7.5.2 version on the 2 clients, but the scheduled backup still fails with error - Probe job had unrecoverable failure(s), this job is being abandoned.

I rebooted my NetWoker server and this also didnt solve the problem.

I then deleted the clients in NMC and recreated them, this also did not work.

When i opened the NetWorker GUI on one the clients it said that the backup server is not registered.

We will be rebooting the 2 clients, hoping that the reboot will fix the comunication error.

I want to know should I uninstall the NetWoker software from the clients and delete them in NetWorker GUI before the reboot and then do a fresh install.

Or should I leave the software installed and then reboot the servers ?

Just want to make sure that I do it the right way, as its very difficult to get downtime on production systems ?

Thanks and Regards!

Re: Scheduled backup fails and Manual backup succeeds

I think that before you start uninstalling and rebooting machines, you should check the name resolution between the clients and servers.  Do you have the hosts files on clients and server correctly filled out with IP,short-name and FQDN?  Does nslookup work from all sides on IP address and hostnames?  You might need to change something on the hosts files or DNS server.

Re: Scheduled backup fails and Manual backup succeeds

I've already checked the name resolutions between the clients and DNS resolves from all ends.

there are no error logs as well, this is a tricky one.

Hoping the reboot could fix it.

Re: Scheduled backup fails and Manual backup succeeds

Is there perhaps a way that I can delete the client completely and re-created the client with a new client id ??

Re: Scheduled backup fails and Manual backup succeeds

I'm not sure how this is going to help with a communication issue, but you can do this by just deleting the client from the NMC and creating a new instance.  It will create it with a new clientid by default.  You could also try putting the ip-address of the client in the aliases field.  This sometimes helps with this sort of issue.

Re: Scheduled backup fails and Manual backup succeeds

Hi Umraan,

One question, you said that you have downgraded the Newtorker version on the clients, what version of Windows Server 2008 are you running on the clients? is it R2?

If its not R2, i would say this is a peer issue, since you downgraded the software but its using the same Nsrladb. (Legato folder is not deleted.)

Please try the following:

Stop Nsrexecd on the client, rename nsrladb on Networker Client installation path, restart Nsrexecd and try the backup again.

It migth be necessary to do the same thing on the server, as it migth not be able to get the fresh peer info from the client if the communication is not correct.

In that case From CMD type Net Stop Nsrexecd to stop all the services on the server, also rename the nsrladb, and restart Netwrker processes.

Hope it helps.

Regards,

Bruno.

Hello,

Re: Scheduled backup fails and Manual backup succeeds

Run savegrp in debug mode ( savegrp -D9) on the client having this issue. The debug output should give you more information on why the probe failed.

Also review the sso files generated under nsr\tmp\sg\<groupname>.

Re: Scheduled backup fails and Manual backup succeeds

I've tried all the above still not able to resolve or find the issue.

Does anyone know how to register a client ?

I deleted the client completely as well as the indix directory of the client, it now says that the client is not registered.

Does anyone know how to re-register a client ?

Re: Scheduled backup fails and Manual backup succeeds

If you've followed the steps in esg67127 (which lists the most likely causes of this)

http://solutions.emc.com/EMCSolutionView.asp?id=esg67127&usertype=C

you should follow the previous advice and run the savegrp in debug mode and check the output and the /tmp/sg/ output for a clearer indication of the source of the problem.
