How to configure RMAN to backup to different disks(mount points).


You need to configure two channels for two mountpoints


Below are the steps.


step i)RMAN> configure channel 1 device type disk format '/d01/stage1/%U.bak';

step ii)RMAN>configure channel 2 device type disk format '/d01/stage2/%U.bak';

step iii)RMAN>CONFIGURE DEVICE TYPE DISK PARALLELISM 2;

step iv)RMAN> configure default device type to disk;

step v)RMAN> backup database;

Then you can verify the backup dumps. It will placed in both stage1 and stage2 mountpoints

ls -l /d01/stage?

or you can write a programme and run the below script.

run { allocate channel c1 type disk maxpiecesize=60m format =
'/d01/stage1/%U.bak';
allocate channel c2 type disk maxpiecesize=60m format =
'/d01/stage2/%U.bak';
backup tablespace example;
}




I hope this helps.. :)
