Streams will break a server into multiple jobs.  It's then up to the
multiplexing settings to handle the tape drives.  
 
Since you say your Storage units have a multplexing settting of 2, check
your schedule for that server and see if your mux setting there is two,
also.  I'll bet that's it.

Subject: [Veritas-bu] streams - full backup



I have recently tried using streams on a particular media server, where I
created 
4 NEW_STREAM directives.  Each are followed by a different mount point that
is 
a seperate filesystem contained on a seperate disk.  Netbackup started 4
jobs, 
2 of which were queued, and used one tape drive for each active stream.  Is
this 
expected or is there something I am not considering in my class setup.  The 
storage device configuration is set to allow two streams per drive so I was
under 
the impression all jobs would have been active at the same time. 


Thanks for any comments or suggestions.
