Oracle 12c multi-tenant CDB and PDB backup ____oracle

First, CDB backup

1.1 Backup only CDB backup CDB database requires a user with SYSDBA or sysbackup permissions to connect to the CDB root environment, execute the backupdatabase root command to complete the backup of CDB, as follows:
[ORACLE@12C01 ~]$ Rman Target/
[Oracle@12c01 ~]$ mkdir/home/oracle/rmanback/
rman> Backup Database root format= '/home/oracle/rmanback/db_%d_%u ';
Rman-03002:failure of Backup command at 05/10/2017 23:14:58
Rman-06817:pluggable Database Cdb$root cannot is backed up in Noarchivelog mode.
Note: Only backup CDB requires the database in the archive environment, the data set to the archive mode.
Rman> select Name,log_mode from V$database;
NAME Log_mode
--------- ------------
ANDYCDB Archivelog
rman> Backup Database root format= '/home/oracle/rmanback/db_%d_%u ';

1.2. Back up the entire CDB and all the PDB below it
Backing up the entire CDB database and all of the PDB below it is similar to a non-CDB database method, using a user with SYSDBA or sysbackup permissions to connect to the CDB root environment, and then execute the backupdatabase command to complete the CDB backup. The method is as follows:
Rman> Backup Database format= '/home/oracle/rmanback/db_%d_%u ';

Second, backup PDB 1.1. Back up single and multiple PDB
Allow backup of one or more PDB databases in CDB (if you are backing up multiple PDB, simply follow the name of the PDB instance you want to back up after the backup command, as the following backup pluggable database pdb1,pdb2; , backing up a PDB database can be backed up by two of the following ways:
Note: If archive mode is not turned on, separate backup CDB or PDB will report ora-19602:cannot Backup or copy active file in Noarchivelog mode
Mode one: Back up one or more PDB databases using the Backup pluggable Database command at CDB root (root).
[Oracle@localhost ~]$ Rman Target/
Rman> backup pluggable database pdb01;

The backup defaults to the Flashback recovery area.

Mode two: Use Backup database in the PDB to back up the currently connected PDB databases, provided that the Tnsnames.ora files are configured.
