Thanks for your input Phil. This is how I have setup my pools, I think
this will do what I want. Once I see how many incremental jobs will fit
a single volume I will adjust the values. Hopefully an entire month will
fit on one volume so I can minimize tape changes. If anyone sees a
problem please let me know because I wish to put this in production on
the first of the month.
Thanks again for your comments, Robert
