On this article I am going to explain how to duplicate a 19c container database with two PDBs, using local backups. To do that, we need first of all, create a backup from target database. Backup must to be done for database and archivelogs as well:

As you don’t need to connect to the target database, Oracle will retrieves the required metadata database to create the auxiliary database from backups that were generated before.
We must create a pfile parameter file from the target database, modify the file with the appropriate values for the auxiliary database and use it to bring up the database.
If target and auxiliary database directories are different, configure the parameters db_file_name_convert and log_file_name_convert to duplicate command create the datafiles and logfiles in appropriate directories. Also, modify parameters to store the new controlfile directories and names on control_files, database name in db_name and audit file destination in audit_file_dest parameter.
Change SERVICE on dispatchers parameter to auxiliary database name and change log_archive_format to an appropriate archive log file name.
Example:
[oracle@oel8lfs ~]$ sqlplus / as sysdba

After you change all parameters, init file should looks like it:
[oracle@oel8lfs ~]$ cat /tmp/cdb19c2.ora
*.audit_file_dest='/oracle/app/admin/cdb19c2/adump'
*.audit_trail='db'

Create directories on OS level, or if you are using ASM, create inside ASM disk group directory:
[oracle@oel8lfs ~]$ mkdir -p /oracle/app/admin/cdb19c2/adump /oracle/oradata/CDB19C2/controlfile/ /oracle/fast_recovery_area/CDB19C2/controlfile/
[oracle@oel8lfs ~]$ ls /oracle/app/admin/
cdb19c cdb19c2
[oracle@oel8lfs ~]$ ls /oracle/oradata/
CDB19C CDB19C2
[oracle@oel8lfs ~]$ ls /oracle/fast_recovery_area/
CDB19C CDB19C2
[oracle@oel8lfs ~]$
After that, we need to start the destination database in NOMOUNT mode using init pfile:
[oracle@oel8lfs tmp]$ sqlplus / as sysdba
