I think what he means is that if he uses in-line copies, he loses one tape
drive per in-line copy which due to the small backup windows would be a
problem. I would seriously look into Storage Lifecycle Policies, because then
you can configure a policy to do a backup at 8PM and then instruct the same
policy to do a duplication later on that evening. The only caveat is that you
can't use Basic Disk units (Standard disk storage, disk staging units, etc.).
If you have the Advanced Disk options, then this isn't a problem. For something
simple like this though, backup to tape followed by a duplication, it would fit
the bill quite nicely.

Have you tested inline copy? My experience has been that it doesn't impact
performance as much as you might think.
