Configuring and Backing Up Oracle Databases Using RMAN - OCP: Oracle Database 12c Administrator Certified Professional - page 134

If you want to duplex an individual backup rather than set a persistent configuration setting,
you would use the SET BACKUP COPIES command within a RUN block, as in this example:
RMAN> run
2> {
3> allocate channel d1 device type disk format 'c:\oracle\backup\%U';
4> set backup copies 2;
5> backup incremental level 0 database plus archivelog delete input;
6> }
In Exercise 3.1, you'll configure some RMAN settings.
