Oracle 12c Multi-tenant CDB and PDB backup

First, CDB backup

1.1 Backup CDB only

To back up the CDB database only requires a user with SYSDBA or sysbackup permissions to connect to the CDB root environment, perform the backupdatabase root command to complete a backup of CDB, as follows:
[[email protected] ~]$ Rman target/
[Email protected] ~]$ 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$root cannot is backed up in Noarchivelog mode.
Note: Backing up CDB only requires the database to set the data to archive mode in the archive environment.
Rman> select Name,log_mode from V$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 its following PDB are similar to non-CDB database methods, using the SYSDBA or Sysbackup permissions user to connect to the CDB root environment, and then execute the backupdatabase command to complete the backup of the entire CDB. Here's how:
Rman> Backup Database format= '/home/oracle/rmanback/db_%d_%u ';

Second, backup PDB

1.1. Backing up single and multiple PDB
Allow backup of one or more PDB databases in CDB (if you are backing up multiple PDB, just follow the backup command with the names of the PDB instances you want to back up, as follows, backup pluggable database pdb1,pdb2; ), backing up a PDB database can be backed up in one of the following two ways:
Note: If the archive mode is not turned on, separate backup CDB or PDB will be reported ora-19602:cannot backup or copy active file in Noarchivelog mode
Mode one: Use the Backup pluggable Database command to back up one or more PDB databases at CDB root (root).
[[email protected] ~]$ Rman target/
Rman> backup pluggable database pdb01;

The backup is in the Flashback recovery area by default.

Method Two: Use Backup database in the PDB to back up the currently connected PDB database, provided that the Tnsnames.ora file is configured properly.
[Email protected] ~]$ Rman target Sys/[email protected]:1521/pdb01
Connected to target database:ANDYCDB:PDB01 (dbid=2550500229)
Rman> Backup Database format= '/home/oracle/rmanback/db_%d_%u ';
