Hi ALL,
EBS R12.2.4
OL6
11gR2
Our database RMAN backup starts at midnight and completes at around 5AM.
Is this backup time too long? or just enough?
I am only using default single parallelism.
run
{
backup as compressed backupset database plus archivelog;
backup current controlfile ;
crosscheck archivelog all;
crosscheck backup;
delete noprompt expired backup;
delete noprompt expired archivelog all;
delete noprompt obsolete;
delete force noprompt ARCHIVELOG ALL completed before 'SYSDATE-12/24';
}
RMAN> show all ;
using target database control file instead of recovery catalog
RMAN configuration parameters for database with db_unique_name PROD are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/home/oraprod/PROD/11.2.0/dbs/snapcf_PROD.f'; # default
Supposing our CPU is 8 cores, How do I speedup the RMAN backup?
Can I speed it up if I run > CONFIGURE DEVICE TYPE DISK PARALLELISM 8 BACKUP TYPE TO BACKUPSET ?
Or do I need to edit my "run" script and add new parameter settings? or no need and just the above configure command is enough?
Please help,
Kind regards,
jc
