Backup pluggable databases

in Database Backup and Recovery (MOSC) 9 commentsAnswered

Oracle documentation states the following:

Backing up a whole multitenant container database (CDB) is similar to backing up a non-CDB. When you back up a whole CDB, RMAN backs up the root, all the pluggable databases (PDBs), and the archived redo logs.

That is straight forward, but I've never tested it. Is it true that backing up the CDB will also backup the ROOT and every PDB inside the CDB? The reason I ask, is I ran a full backup of a CDB and it ran so fast that I questioned what it was backing up. I ran the backup through OEM using RMAN script generated by OEM. I simply did a full backup of the CDB.

Howdy, Stranger!
