I don't know if it does or not.
Will find out though, thanks.

Jared,
RMAN supports DATAFILE COPY - which is essentially a RMAN-catalogued *disk*
copy of the datafile. I am not sure if this can handle multiple files
automatically (forgot lots of RMAN stuff once I cleared my 8.0/8i OCP a few
years back :)) - I assume so since I see a 'DATAFILECOPY' tag that can be
added. If so, shouldn't this address your issue?
