RMAN backup skip tablespace using EXCLUDE feature

RMAN backup skip tablespace using EXCLUDE feature

To Skip the tablespace during backup database

export ORACLE_SID=PROD
sqlplus / as sysdba

SQL> select * from v$tablespace;

TS# NAME INC BIG FLA ENC
———- —————————— — — — —
0 SYSTEM YES NO YES
1 SYSAUX YES NO YES
2 UNDOTBS1 YES NO YES
3 TEMP NO NO YES
4 USERS YES NO YES
5 PROD_DATA YES NO YES
6 PROD_INDX YES NO YES

10 rows selected.

sql exit

rman target /

rman>show exclude;
using target database control file instead of recovery catalog
RMAN configuration parameters for database with db_unique_name PROD are:
RMAN configuration has no stored or default parameters

RMAN> CONFIGURE EXCLUDE FOR TABLESPACE PROD_DATA;

Tablespace PROD_DATA will be excluded from future whole database backups
new RMAN configuration parameters are successfully stored

RMAN> CONFIGURE EXCLUDE FOR TABLESPACE PROD_INDX;
Tablespace PROD_INDX will be excluded from future whole database backups
new RMAN configuration parameters are successfully stored

RMAN> show exclude;
RMAN configuration parameters for database with db_unique_name PROD are:
CONFIGURE EXCLUDE FOR TABLESPACE ‘PROD_DATA’;
CONFIGURE EXCLUDE FOR TABLESPACE ‘PROD_INDX’;

RMAN> BACKUP DATABASE;

Starting backup at 08-JUNE-10
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=129 device type=DISK
file 5 is excluded from whole database backup
file 6 is excluded from whole database backup
channel ORA_DISK_1: starting full datafile backup set
channel ORA_DISK_1: specifying datafile(s) in backup set
input datafile file number=00001 name=/u01/oradata/SYSTEM01.DBF
…….

We can override the exclude feature explicitly during database backup.

RMAN> show exclude;
RMAN configuration parameters for database with db_unique_name PROD are:
CONFIGURE EXCLUDE FOR TABLESPACE ‘PROD_DATA’;
CONFIGURE EXCLUDE FOR TABLESPACE ‘PROD_INDX’;

RMAN> BACKUP DATABASE NOEXCLUDE;

To Clear the EXCLUDE feature:

RMAN> CONFIGURE EXCLUDE FOR TABLESPACE PROD_DATA CLEAR;
Tablespace PROD_DATA will be included in future whole database backups
old RMAN configuration parameters are successfully deleted

RMAN> CONFIGURE EXCLUDE FOR TABLESPACE PROD_INDX CLEAR;
Tablespace PROD_INDX will be included in future whole database backups
old RMAN configuration parameters are successfully deleted

RMAN> show EXCLUDE;
RMAN configuration parameters for database with db_unique_name PROD are:
RMAN configuration has no stored or default parameters
Note:- This will only work while taking backups with RMAN. While cloning or while duplicating we can use :skip tablespace tba_name" to skip particular database.
