D:\Program Files\Veritas\NetBackup\bin\admincmd>

So, backup selection is as below:

Include:           /ellstage/undo
Include:           /elltest/system
Include:           /elltest/redoD
Include:           /elltest1
 and multistreaming enabled. When i start backup it is showig seperate streams for each FS, but in the details it is doing backup of same files. PLease find the screenshots. i have attached scrrenshot of two jobs, but this is same for all four.

Can you please tell me why is this happening? Why four different job for four different file systems, job details are same for all four even KB speed.

Little bit about file system:

 

Source File system Destination Mount Point
filer1:/vol/server2_ellstage/undo       /ellstage/undo
filer1:/vol/server2_ellstage/system     /ellstage/system
filer1:/vol/server2_ellstage/redoD      /ellstage/redoD
filer2:/vol/server2_elltest1/test1      /elltest1

****changed the server names just for security reasons.

Master: NBU 7.0.1, OS: win2008 R2

Media: NBU 7.0.1, OS: win2008 R2

Thanks!

what do you see if you look at the client server Destination Mount Points ?

Sorry, i did not understand you. can you please let me know in few details what exactly you want?

The 4 jobs are because u have the Multi_streaming option enabled, this will generate a job by NFS or mounted FS.

Sorry, my question is not that. I know why i have four jobs, but I did not understand why job details are same for all four jobs. Did you have a look into the screenshots. i gave two of them as an example.

when you log in to server2 and check the various NFS mount points, are they really different as you expect or are they pointing to the same place, thus the results you are seeing in NetBackup details.

One other thing in addition to the advice above ...

You have 4 streams and enabled allow multiple streams - but you have not split them on the policy selections list, so each one could potentiall try and look for streams

The policy selections list should look like:

NEW_STREAM
/ellstage/undo
NEW_STREAM
/elltest/system
NEW_STREAM
/elltest/redoD
NEW_STREAM
/elltest1

Always haveing a NEW_STREAM statement first

Hope this helps

Mark, as per NetBackup admin guide there is no necessarity to add NEW_STREAM into the backup selection if you want normal streams like seperate job for each backup selection (for each raw). NEW_STREAM work when you want to customize the streams, like two backup selection as one job and etc...

I dont think this will help.

What you have selected backup selection as All loacl drives or each mount point you have selected?
