Sorry to comment on this so late but -
I don't understand the concern about the directive or scripting solution
generating multiple savesets, or why it could be bad for a DR.
If I had millions of files in a single saveset I could only read this as a
single stream, if this was split into multiple savesets I could read
multiple streams - even better if the savesets are spread across several
tapes I could read from several drives at once.
I would be more worried about the effects on the client as multiple reads
or writes to a sinlge filesystem might bottlenecl on the r/w to the disk.
