I resync everday after i do full backup and controlfile backup.
It generate 4 to 5 gig archive logs/day.
below is the script i use to create duplicate database
rman catalog rman/rman@rman target internal/oracle@prod auxiliary internal/oracle@dup
set auxname for datafile 1 TO 'E:\ORACLE\ORADATA\dup\SYSTEM01.DBF';
set auxname for datafile 5 TO 'E:\ORACLE\ORADATA\dup\RBS04.DBS';
set auxname for datafile 2 TO 'E:\ORACLE\ORADATA\dup\USERS01.DBF';
set auxname for datafile 3 TO 'F:\ORACLE\ORADATA\dup\RBS01.DBS';
set auxname for datafile 4 TO 'G:\ORACLE\ORADATA\dup\TEMP01.DBF';
set auxname for datafile 6 TO 'E:\ORACLE\ORADATA\NUCOPY\INDX01.DBF';
and so on..............
run {
allocate auxiliary channel d1 type 'sbt_tape';
