Oracle Database Backup
We can use the Oracle Data Pump technology for Oracle 10g, 11g, 12c, 18c and 19c databases.
First create an Oracle directory BACKUP_DIRECTORY that points to an operating system directory on the database server machine for reading and writing files.
Assume ORCL is the database server name or SID.
Sqlplus.exe / as sysdba
CREATE OR REPLACE DIRECTORY BACKUP_DIRECTORY as '/backups/Oracle';
GRANT read, write ON DIRECTORY BACKUP_DIRECTORY TO MM;
Then use Oracle Data Pump ( expdp , impdp ) to backup and restore the metadata repository.
