Hello,

I had an issue this day, with backups using source deduplications.

I am trying Symantec appliances (N5020) and I do several reset of the storage pool of my appliances (before, I had deleted images, did an image cleanup, deleted storage unit, disk pool and storage server). 

My firsts backup with source deduplication were ok, but after appliance reset, some of them failed with status code 83. In the job log, I had :

I searched and found the problem : config file of the deduplication plug-in was misconfigured. It had old password and was unable to connect with the appliance. 

You can confirm this with appliance log (in the web interface) : you will have authentication errors with the clients of your failed jobs.

It was very strange because :

  • I used exactly the same parameters to create new storage pool on appliance and Netbackup (same name, password, etc.). I do not understand why password need to be changed in the config file. But on the news client, when cfg file is created, I could confirm that password line was different of the one I got on "bad" clients
  • Netbackup client 7.0.x (or 7.0.x updated in 7.1) had not the problem, because config file is different (password line contains only stars, and not hashed word)

The solution :

It is very simple : you only need to delete cfg file of dedup plugin on your client (C:\Program Files\VERITAS\NetBackup\bin\ost-plugins\*.cfg), and it will be generated with good parameter with the next backup. 

Note : 

Netbackup documentation says that you need to delete config file but we do not know where (client ? media ?)

Thanks for sharing the information. May I ask the path where we have the cfg files on Linux?
