netbackup doubts

Hi ALL, I have some basic doubts.i have studying the NBU docs and pdfs.and also google. 1. restart folder and ffile logs under /usr/openv/netbackup/db/jobs contains what information. try logs: detailed information of job ffilelogs: backup selection of a job. restart logs: ??? 2...What is an EEB..is it a patch on the current version or what. is it an exe file or what. ffile logs contains: backup selection of the job try logs: detailed information of the job. The /usr/openv/netbackup/db/jobs/trylogs directory contains .t files which store details for individual backup jobs. These files are then read by the bpdbjobs command to display job information. restart logs:

    Out of the questions, to be fair, the trylogs is useful, as this is effectivly the same as the detailed information in the GUI for a job = easily searchable via the command line (grep etc ... if on Unix)

    The others I would forget about ...

    The ffilelogs is indeed the backup selection for a job - not something I've ever needed to use.

    I don't think I have ever looked in restart until today ...  Given, at least on my system it contains files with jobids that have failed backups, it would appear, that NBU will use this information to restart the failed job should it wish to do so.  In fact it does, as I have just deleted of the files and now cannot 'restart' that particular job.

    Why do you need this level of detail regarding the jobs database?

    EEB = Emergency Engineering Binary
    This is a patch to fix a problem before the next official NBU patch or minor version is released.

    Thanks Marianne.

     

    Actually in the training this has been asked many times by the symantec trainees.

    Actually in the training this has been asked many times by the symantec trainees.

    And what was the trainer's answer?

    In my 16 years of working with NetBackup, I have never needed to know about each folder in the jobs database and its function...

    Hi Shashi - I had exactly the same reaction when I read your post - in all my years with NetBackup I have never even once had to manually go in to the jobs database folders and trylogs - take it from us, there's no value in understanding these binary files.  I've worked on NetBackup since v4.5, and I've never had to go in there.

    To be honest, I for one, cannot answer your question because I don't understand the structure of these files.  I've never had to.  All I have ever needed to do is use the "bpbdjobs" command to query the jobs database.  I very much think that if you were to manipulate, or even lock, even just one of the files in the try logs area then you will almost certainly break NetBackup.  I'm not aware of any commands to manipulate these files outside of, or within, NetBackup.  This isn't something that a NetBackup admin/engineer does.  In fact these files have no relevance whatsoever when designing, implementing, documenting, supporting, administering NetBackup.

    I can't ever remember opening a support case and having to manipulate the files.  And I can't recall any tech notes or scripts or documentation around these files.  The only roles that I think would be interested in these files are the the programmers and developers of NetBackup.  Are you a programmer for NetBackup?  Or are you a programmer for a third party tool and trying to "read" or "control" NetBackup without using one of the normal native NetBackup CLI commands?

    Ok - have fun fiddling with (and reading (and holding open (and locking))) application meta-data files underneath NetBackup.  I'm fairly sure that NetBackup Server will apreciate that.  I think I'll stick to the documented and supported command of "bpdbjobs", and the scripting is easier with this command too.

    Just to reinforce SDOs points - apart from a quick cat <trylog> I wouldn't touch any of the files personally - as I briefly demonstrated in my previous post  (on a test machine) doing so breaks NBU ...

    I'm struggling to understand why a NBU trainer is going anywhere near these files.
