Oracle RMAN ( Recovery Manager ) Backup Tutorials -6 Full Backup Database in Oracle via RMAN

Hi,

I will continue to tell you about the RMAN (Recovery Manager) tool in this sixth article of my tutorial series .

Oracle RMAN2

 

 

Read Older articles of my rman backup tutorial series before this article with following links.

 

You should take backup compressed and parallel for using storage effective and increasing backup performance.

 

We will take backup of database,archivelog and controlfile with 8 parallel and compressed like following script. You should put rman commands into run block if you are using multiple commands in same script.

 

run{
ALLOCATE CHANNEL CH1 DEVICE TYPE DISK;
ALLOCATE CHANNEL CH2 DEVICE TYPE DISK;
ALLOCATE CHANNEL CH3 DEVICE TYPE DISK;
ALLOCATE CHANNEL CH4 DEVICE TYPE DISK;
ALLOCATE CHANNEL CH5 DEVICE TYPE DISK;
ALLOCATE CHANNEL CH6 DEVICE TYPE DISK;
ALLOCATE CHANNEL CH7 DEVICE TYPE DISK;
ALLOCATE CHANNEL CH8 DEVICE TYPE DISK;
BACKUP AS COMPRESSED BACKUPSET DATABASE FORMAT '/u01/backup/FULL_%d_%u_%s_%T.bkp';
BACKUP AS COMPRESSED BACKUPSET ARCHIVELOG ALL not backed up 1 times FORMAT '/u01/backup/Archivelogs_%d_%u_%s_%T.bkp';
BACKUP CURRENT CONTROLFILE FORMAT '/u01/backup/CONTROLFILE%d_%u_%s_%T.bkp';
RELEASE CHANNEL CH1;
RELEASE CHANNEL CH2;
RELEASE CHANNEL CH3;
RELEASE CHANNEL CH4;
RELEASE CHANNEL CH5;

RELEASE CHANNEL CH8;
}

 

We are taking compressed and 8 parallel full database,archivelogs and controlfile backup like following.

You need to take backup of database,archivelogs and controlfile for regular backup in a production database. Because if you take only database backup, you cannot open database with just database backup. Because Oracle needs firstly controlfile then database backup finally archivelogs for recover database.
