New Stream

Good morning all,

I have a problem with a policy using the New Stream on my 7.6 Netbackup running NDMP.
On attributes I ticked "Allow multiple data streams" and on Backup Selections I have:
Vol1
vol2
vol3
NEW_STREAM
vol4
vol5
vol6

My expectation was to have a parent job and two child jobs, so vol1, vol2 and vol3 to go on one job to one tape and vol4, vol5 and vol6 to go on another job to another tape, so my expectation was to have 2 tapes used.
What happened was that Netbackup ran one job for vol1, one job for vol2 and so on until one job to vol6 and one more job that was the parent job, 7 jobs in total.
I don't know what I have done wrong to Netbackup act like this, any idea how to fix this?
This is my current policy:

Thank you very much!!

  • Try putting this just before your /vol1 selection

    NEW_STREAM

    so it looks like this:

     

    NEW_STREAM
    /vol1
    /vol2
    /vol3
    NEW_STREAM
    /vol4
    /vol5
    /vol6

     

    I've never tried it, so give it a go

  • http://www.ndm.net/isilon/pdf/ndmp-configuration-guide-for-symantec-netbackup.pdf

    Page 22 shows a screenshot showing that NEW_STREAM must come first before your /vol1 selection as I mentioned above. Give it a try and report back.

  • Not sure if NEW_STREAM is supported in NDMP policy.
    I cannot find anything in NBU for NDMP Admin Guide.

    If MPX in schedule is set to 3 and you have 6 items in Backup Selection, there should be 6 jobs with 3 backups each per tape drive.

  • That was initially what I wanted to suggest, but I cannot find anything in the NDMP guide to say that this is supported.

    Worth a try though...
