Hello,

I am trying to achieve the streaming of five mount points on an HP-UX client to one LTO-1 tape drive.  I have run into a strange issue though.

If I set multistreaming to five, and multiplexing to five, I see each stream as a job in the activity monitor. However, NBU is breaking up each mount point into five streams - not what I want. I want one stream for each mount point.

Symantec support has instructed me to turn off multistreaming in the policy, and leave multiplexing set to five. When I do this, there is only one job in the activity monitor for the client, and I cannot verify that I am multiplexing the mount points to the tape drive. Also performance is not what it should be for this backup, running at 13 hours instead of the five or six I would normally expect for roughly 420 gb of data.

My environment looks like this:

Master = SPARC / Solaris 10 / NBU 6.0 MP4
Media Server = PA-RISC / HP-UX 11.11 / NBU 6.0 MP 4
Client = PA-RISC / HP-UX 11.11 / NBU 6.0 MP 4

I am using the ALL_LOCAL_DRIVES directive, with an exclude_list of "/". I have an include_list that specifies the mount points I want to back up.

Does anyone have any suggestions that will help me to verify that I am in fact multiplexing the mount points to the tape drive during the backup?

Any suggestions and feedback are welcome. Thank you for your help.

Regards,
Jeremy
