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.

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.

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

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.

Hello,

Check the windows firewall on client server.

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.

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 ?

Hi Bobby,

I followed the steps in the link you sent me.

I stopped NetWoker services on both client and server, backup is still failing.

One of the network engineers advised that its the ipv6 address that is causing the issue with reverse DNS lookup.

thanks for all the responses in helping me get this issue resolved, its much appreciated!!!

I'll keep you posted.

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.

Hi

I ran the backup from the command line on the client using the -D and I got the following.

It looks suspect to me but not sure what its telling me.....I know its authentication

I only cpoied the important info:

perhaps someone can tell me what this means ?

What I would do is

1) tun off IP V6 unless your whole network has been change over to it.  I would bet you do not need it.

2) in your hosts file add the IP address and name short and full for both the server you wish to back up on and the networker backup server and any proxy you are using if any.  do this on both sides networker server and client.

If you still have the problem.

3) delete the group and client in the networker (GUI) and then recreate them.   (this is from a old bug that comes back some times.  I am not on 7.5.5 but on 7.4.4 and before it was their)

I managed to fix the problem.

It was in fact a  reverse DNS lookup issue.

the network engineer also mentioned to me that the IPV6 address also caused the conflict between the servers.

Thank you all for the input, its much appreciated!!
