INSERT INTO BACKUP_TBL SELECT FROM SOURCE_TBL;

SQL> CREATE TABLE <new_table_name>
     AS SELECT * FROM <original_table>;

That is one way, CTAS.

A bit faster.

create table
    new_mytab NOLOGGING PARALLEL <degree>
as
    select * from <mytab>
tablespace
    new_tablespace;

Is it one time or routine job?

[EDIT] And start using Million, Billion, because people may not understand lakh here.

 especially in the city of Karachi, the word "peti" is also used to denote one lakh rupees

There are many other words even - 'peti' , 'khokha', etc. It's all regional.

For those who do not understand 17 lakh, it means 1.7 million.

@OP : With CTAS as suggested above, it should not take more than just a couple of seconds. Read these links,
