It will show each "stream" as if it were 3 different jobs in the
activity monitor.  The first job will show you the mounts/positions
etc... for the entire "stream" and the other two jobs show you the
respective mounts/positions etc... for the specific copy.   So if you
have (as we do) a job that you've broken into 3 streams doing in-line
copies you'll actually see 9 jobs for it using a total of 6 tape drives.

Hi all, 

I am trying to understand how ITC works, Does it split the IO at the
media server or requires more client streams to generate the multiple
copies?

I have a customer which has a problem similar to this one: 
http://www.arcknowledge.com/gmane.comp.sysutils.backup.veritasbu/2005-12
/msg00502.html
<http://www.arcknowledge.com/gmane.comp.sysutils.backup.veritasbu/2005-1
2/msg00502.html>  

And would like to know your experience on ITC. 

Thanks in advance, 

Tarso
