Hi Guys,
Oracle 11g Release 2 introduced new feature in RMAN utility i.e TO DESTINATION keyword.
Generally while taking RMAN backup either we have to configure the channel or allocate the channel to store backup pieces. You can bypass these locations ,to store backup in new location.
Note there is no format string like %U in the above command as we have been using in the backup commands earlier. Here is the output:
Your database should be in archivelog mode.
This clause creates backup files in an organized manner. The above command creates a directory OCP (the name of the instance), under which it creates a directory called backupset, under which another directory with the name as the date of the file creation. Finally the backuppiece is created with a system generated tag. When you use this to backup archived logs, that backuppiece goes under the subdirectory archivelogs and so on.

RMAN>
This clause creates backup files in an organized manner. The above command creates a directory OCP (the name of the instance), under which it creates a directory called backupset, under which another directory with the name as the date of the file creation. Finally the backuppiece is created with a system generated tag. When you use this to backup archived logs, that backuppiece goes under the subdirectory archivelogs and so on.
You an also use this clause in ALLOCATE CHANNEL command as well:
RMAN> run {allocate channel c1 device type disk to destination '/tmp/backup';
backup tablespace USERS;
release channel c1;
}
released channel: ORA_DISK_1
allocated channel: c1
channel c1: SID=35 device type=DISK
