20. 20 Backup configuration Incremental 0 once a week Incremental 1 the other days of the week All backups are followed by logical validation Archived log backup done during the day (for now) Once we move to the new hardware the archived log will be multiplexed on a shared disk outside ASM Backup are stored on the local disk Backup are copied from the local disk to tape and kept for three months

21. 21 Backup configuration RMAN configuration parameters are: –CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 8 DAYS; –CONFIGURE BACKUP OPTIMIZATION ON; –CONFIGURE DEFAULT DEVICE TYPE TO DISK; –CONFIGURE CONTROLFILE AUTOBACKUP ON; –CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/oracle_backup/pluto/%F.bak'; –CONFIGURE DEVICE TYPE DISK PARALLELISM 2 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 '/oracle_backup/pluto/pluto_%U.bak'; –CONFIGURE MAXSETSIZE TO UNLIMITED; –CONFIGURE ENCRYPTION FOR DATABASE OFF; –CONFIGURE ENCRYPTION ALGORITHM 'AES128'; –CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; –CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/opt/oracle/app/oracle/product/10/db_1/dbs/snapcf_pluto1.f'; # default

22. 22 Backup configuration Incremental 0: –backup incremental level 0 duration 12:00 database; –backup archivelog all delete all input; –report obsolete; –delete noprompt obsolete; Incremental 1: –backup incremental level 1 duration 12:00 minimize time database; –backup archivelog all delete all input; Validation: –restore validate check logical database archivelog all;
