A basic rman configuration (backups to disk):
RMAN> show all; RMAN configuration parameters for database with db_unique_name TINUS are: CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 31 DAYS; CONFIGURE BACKUP OPTIMIZATION ON; CONFIGURE DEFAULT DEVICE TYPE TO DISK; CONFIGURE CONTROLFILE AUTOBACKUP ON; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u04/backups/tinus/%F'; CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/u04/backups/tinus/%U'; CONFIGURE MAXSETSIZE TO UNLIMITED; CONFIGURE ENCRYPTION FOR DATABASE OFF; CONFIGURE ENCRYPTION ALGORITHM 'AES128'; CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE; CONFIGURE RMAN OUTPUT TO KEEP FOR 31 DAYS; CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/19.3/dbs/snapcf_tinus.f'; # default RMAN>
Take care…this is a starting point.
A lot of adjustments can/should be made to give a optimal configuration for your case.
