Actually, I was only answering the "why would anyone want this
information" question in the previous post.  We have tools and scripts
which gather what we need to tune our environment appropriately - taking
into account the information that you mentioned (backup windows, long
running clients, OS and network restrictions) and including the number
of sessions running per drive.  Now, if we only had an unlimited budget
to spend on our environment.... :-)

Hello, 
I don't think it would be easy for us ( me) to guess what is your
environment like ? i.e Do you use DDS, VTL, Dedupe ? clones ? 
What kind of data do you backup, what os, how much data and how long
does it take currently to backup , which clients are taking the longest
? 
Not to even get into hardware configurations , it is difficult to
imagine what is the best approach for you without this info. 
One thing to look for is what is your backup window and are you
accomplishing it now, have you done a proper load balancing of jobs,
pools, devices and clients ? 
If you are finishing the backups in reasonable time without any of the
systems being stressed then you may not need to make wholesale changes. 
If you are having problems, find out which groups\clients take the
longest, then analyze  the backup process for this problem servers\nodes
and make 
one change at a time ( Can you use GB network, can you implement
additional SN, Could you archive the data, lan free, ndmp  are some
example of what you can look at). 
Depending of the issues you may have, there is going to be multiple
approaches to resolve them within the current backup framework and\or
with additional technologies might benefit you. 
HTH

We've also chased after this information for performance reasons.  We
have 10 tape drives, two storage nodes and 3 different tape pools.  We
want this information so we can tune our configuration.  For example, do
we have enough tape drives dedicated to each tape pool on each storage
node?  Overall, does each storage node have enough tape drives allocated
to it?  

If there are LOTS of sessions writing to a single drive for 5 minutes,
that's ok for restores.  The 5 minute backups are fairly small and will
recover quickly regardless of horrible multi-threading.  If, however,
there are LOTS of sessions going to a tape drive for hours, then we need
to solve that problem so that we have a reasonable restore speed.
Having this information can help to justify spending money to expand or
upgrade the backup environment.

Thanks.
Teresa

I can't understand of what use this data would be... If it is possible
to capture this data in text format, what could it be used for ? You
would simply be getting a snapshot in time of the current save sessions
running at that moment. Come back five minutes later, you now have a
different picture compared to what it was before. The number of current
sessions is constantly in a state of change, as sessions complete, new
ones start, until the work-list of all save-sets for the entire group
and all its clients is exhausted.... Then the group completes and
triggers a savegroup completion event... 

Who wants this and for what purpose ???
