As far as I know rman backup as copy can copy online files when DB is
in archive mode.
See example - I don't have DB with ASM right now but it really doesn't
matter where a source file is placed.

RMAN> backup as copy format '/u01/oracle/system01.dbf_%s' datafile 1;

You can do also rman duplicate if you want to create a running copy of
production database - starting with 11g you can do that without
