Table Backup

Question

Hi,
I want to take the backup of a table through query.
i tried
create table as select * from org_table;
but above query does not copy the constraints and indexes from the original table.Can some one help how to copy the same table as it is from the original except manually doing it.
Below is the structure of the original table
-- Create table
create table CITI_USER_DATA_CUSTOMIZE
UNIQUE_ID NUMBER(20) not null,
NAME VARCHAR2(20) not null,
VALUE CLOB
tablespace TS_CITI
pctfree 10
initrans 1
maxtrans 255
storage
initial 128K
minextents 1
maxextents unlimited
-- Create/Recreate primary, unique and foreign key constraints
alter table CITI_USER_DATA_CUSTOMIZE
add constraint CITI_PK_DATA_CUSTOMIZE primary key (UNIQUE_ID,NAME)
using index
tablespace TS_CITI_IDX
pctfree 10
initrans 2
maxtrans 255
storage
initial 64K
minextents 1
maxextents unlimited
alter table CITI_USER_DATA_CUSTOMIZE
add constraint CITI_FK_USE_BAS__US_DA_CU foreign key (UNIQUE_ID)
references CITI_USER_BASE (UNIQUE_ID)
deferrable;
-- Grant/Revoke object privileges
grant select, insert, update, delete on CITI_USER_DATA_CUSTOMIZE to CITI_USER_APTHGCB_OBJROLE;
grant select, insert, update, delete on CITI_USER_DATA_CUSTOMIZE to CITI_USER_OBJROLE;
grant select on CITI_USER_DATA_CUSTOMIZE to JFPQRY_OBJROLE;
grant select, insert, update, delete on CITI_USER_DATA_CUSTOMIZE to JFP_USER;
grant select, insert, update, delete on CITI_USER_DATA_CUSTOMIZE to JFP_USER_APTHGCB;

You can try to :
1. use DBMS_METADATA.GET_DDL to retrieve constraints and indexes from source table (see an example for constraints in Re: Definition of a CHECK constraint
2. process DBMS_METADATA.GET_DDL output to replace some names such as index names for the target table.
