backup failed because of other clients interfering

Question

hi,
i am facing a problem while backing up a certain client. the problem is that, fp2-srvr is the passive node in a two node cluster. when doing a nslookup for fp2-srvr from the backup server, it is returning the private IP address of the cluster. for my knoweldge it shoudn't. so i removed it from DNS and it still there. then the problem was solved and the cluster was backed up successfully.
now, i tried to backup a certain client and created for it a new group. so, the situation is: a group contains one client only which is not clustered. i tried to back it up and it was corrupted saying that restarting nsrmmd#7 on fp2-srvr, and fp2-srvr is not even included in the group. so, i started the networker services on fp2-srvr, and the backup was successful.
why was the backup process trying to restart nsrmon on fp2-srvr and it wasn't even in the group that was backed up?

thank you

Yes, but even if they are not started and your backups are not destined to these storage nodes, backups would happen.

The only issue is the performance overhead caused when Networker server keeps checking its nsrmmd on all storage nodes.

In one of my low configuration backup servers, the server itself failed due to lack of resources as it was retrying starting nsrmmd on a storage node which was not working.

Because server noticed that remote nsrmmd is not responding it tried to restart it - this is normal behavior and unrelated to backup. Server keeps tracks and tests its nsrmmds if they are available according to timer settings.

I have no idea what you wish to say when saying 'interfering'. Backup will continue until certain timeout. NetWorker services/daemons should always be started (at least for storage nodes that would be fact unless you wish to disable jukebox which would disable devices and softly kill nsrmmds).

so why it didn't happen with other clients interfering, and should the backup be stopped or it should continue backing up after a while.
what if i created two backup groups and split their times that no one will interfere with the other backup process. will one of the group still be interfered with the other and trying to restart nsrmmds of other group clients.
should the networker services of all clients be started even if they are not included in the bachup group?

thank you

so, what i really got is that all networker storage nodes services should be started although if they are not in the backup group.
