    I have an example, FYI:
    Consider u had done a full database backup with RMAN, so it's a level 0 backup, I use this sentence:
    BACKUP INCREMENTAL LEVEL 0 DATABASE;
    And the level 1 backup sentence is:
    BACKUP INCREMENTAL LEVEL 1 CUMULATIVE DATABASE;
    or:
    BACKUP INCREMENTAL LEVEL 1 DIFFERENTIAL TABLESPACE users;
    By the way, u can reference Oracle doc(no:b14194).

    for level 0 i used this code:
    rman> run{
    allocate channel c1 type disk;
    backup database filesperset 2 format 'aug%s%t';
    }

    this i took backup on 5th august. now i dont want to take full database backup. whatever changes happend only that backup, incremental backup i want to take. but code i dont know. ex: i am trying in this way.

    rman>run{
    allocate channel c1 type disk;
    backup database incremental level 1 format 'aug%s%t' filesperset 2;
    }

    my problem is i dont know the code at all.

    Plz help me in giving code both in cumulative and differential.
