Instead, Please have a look at DEF STG or UPD STG with COPYSTGpools
option which allows you to write backup to primary pool and multiple
copy pools simultaneously.

Thanks for that Mark! 

I have one small follow up question: 

can I do the same with my management class and specify in the backup
copy group that the initial backup goes to two storage pools
concurrently?  What I'm getting at is being able to write my nightly
backups to 2 places at the same time (for D.R. purposes) as opposed to
writing them to a storage (disk) pool and then copying them to two copy
(tape) pools in different locations?

Sure. Create a text file that contains the lines
 
  backup stg diskpool copypool1
  backup stg diskpool copypool2
 
Save the file as 2copywrites.scr
 
>From the TSM administrative command line:
 
  tsm> define script 2copywrites file=2copywrites.scr
 
Schedule an administrative task:
 
  tsm> define sched 2copywrites t=a cmd='run 2copywrites' active=yes
desc='Write client data from DISKPOOL to both copypools concurrently'
 
Piece o' cake.

Hi List



With my current version of TSM (5.1.6.3), I know that I can copy from
storage pool to copy storage pool using as many processes as required
making it multi threaded..



In later versions of TSM (or perhaps in the future)... does anyone know
whether it is / will be possible to perform a dual write from my disk
storage pool to multiple copy storage pools at the same time? (I
understand Netbackup can do this!!)



Thanks in advance
