    The parameters that  I asked you to checks are BASICS....

    What type of storage unit have you created for backups? (The backup destination selected in SLP)

    Depending on the type of disk storage unit, you need to select the max number of simultaneous jobs that can write to the STU. 
    You do this when you create the STU or afterwards by editing the STU.
    From cmd, you can show us with this command:

    bpstulist -L 
    (command is in ....netbackup\bin\admincmd)

    If you want a single client to run more than one job simultaneously, you go to Host Properties -> Master Server -> Global Attributes

    Multiplexing in Policies is selected in the Schedules. The default is 1.

Dear Ma'am,

 

How many simultaneous jobs are allowed in Storage Unit properties (the STU selected for backups)?
What is Max Jobs per Client set to in Master server Host properties?
Is multiplexing enabled in Policy schedules?

Please show us the text in Details tab of a queued job.

    Hello Ma'am,

    I found few parameters on NBU forum, regarding the concurrent jobs.

    Please see below

    (-cj)max_jobs for storage unit 

    policyjobs(max jobs) for policy

    multiple_streams for Policy

    But i didn't find that much information about these parameters.

    can you please let me know about it?
