Backup container database in oracle 12c

Container Database (CDB) Backup

Backup of a Container Database (CDB) is essentially the same as a non-Container Database. The main thing to remember is, by doing a full backup of the CDB you are also doing a full backup of all PDBs.

Connect to RMAN using OS authentication and take a full backup using the following command. This means you are connecting to the root container with "AS SYSDBA" privilege.

RMAN> backup database plus archivelog;

PDB database backup

Pluggable Database (PDB) Backup

There are two ways to back up pluggable databases. When connected to RMAN as the root container, you can backup one or more PDBs using the following command.

$ rman target=/

RMAN> BACKUP PLUGGABLE DATABASE pdb1;
