On page 132 of the 5.1 Sys Admin Guide, you can start
reading about "Directives for Multiple Data Streams."

Using the NEW_STREAM directive is possible in this
case, but I think the auto-discover with " dir/* "
wildcards is better for your environment because it
automatic produces a new seperate stream for every file
and directory.

I'm trying to backup a directory and we are currently
using multistreaming ("Allow Multiple Data Streams"). 
We use the "Auto-discover Streaming Mode" feature since
we use wildcards on our file list which currently
consists of:
/dir/*

This creates a new stream for every file and
sub-directory under "/dir" and this works for us since
this data is located on very fast SAN disk and we limit
the number of jobs per policy.

We have a couple of sub-directories that we would like
to multistream even further since they contain the
majority of the data.  Something along the lines of:
/dir/subdir/*

The question is how do we keep the administration
simple, but at the same time not duplicate the data
being backed up.  The sub-directories can vary in name
and can be added or removed by our developers at any
time, but they will always end in "data" in the
sub-directory name.  I've tried this file listing
configuration:
/dir/*
/dir/*data/*

but the "data" sub-directories are being backed up
twice.

Any ideas on how to do this with a single policy?  

Is the answer to use 2 policies and have an exclude
list on the first to exclude the specific
sub-directories?

peace,
