I think the explanation is that the BACKUP command makes a backup piece,
which is an rman-proprietary file that can only be read by RMAN. The
COPY command (and the ALTER DATABASE BACKUP CONTROLFILE command) makes a
byte-for-byte copy of the file, which can be used by an Oracle database
directly w/o any further manipulation required from RMAN. For example
datafile and control file *copies* can be copied from disk to disk or CD
or another server as-is and used to startup a cloned instance, but a
*backup piece* containing datafiles and/or log files and controlfiles
must first be RESTOREd by rman before it can be used by a database.

Brandon

I find myself puzzled about how RMAN is functioning.
