1/ Export is NOT a backup strategy.

You can let Export prompt you for parameters by entering the EXP
command followed by your username/password:
Example: EXP SCOTT/TIGER
Or, you can control how Export runs by entering the EXP command followed
by various arguments. To specify parameters, you use keywords:
Format: EXP KEYWORD=value or KEYWORD=(value1,value2,...,valueN)
Example: EXP SCOTT/TIGER GRANTS=Y TABLES=(EMP,DEPT,MGR)
or TABLES=(T1:P1,T1:P2), if T1 is partitioned table
USERID must be the first parameter on the command line.

What is "2003" in your topic's title? Oracle database version? Operating system version? A year you remember for great holidays you had?
I'm just kidding; however, perhaps you'd want to read the OraFAQ Forum Guide. It would help you ask questions and - at the same time - other Forum members answer them much more easy.
Although command prompt help helps, you might be interested in reading the documentation; this is the Oracle 10g Utilities book; as you deal with Export and Import, check chapter 19: Original Export and Import.
