It is extract of Oracle8i Utilities Manual.

Important: Incremental, cumulative, and complete Exports are obsolete features
that will be phased out in a subsequent release. You should begin now to migrate to
Oracle’s Backup and Recovery Manager for database backups. See Oracle8i
Operating System Backup and Recovery Guide for more information.
Restrictions:

You can do incremental, cumulative, and complete exports only in full
database mode (FULL=Y). Only users who have the role
EXP_FULL_DATABASE can run incremental, cumulative, and complete
Exports.

I think that incremental export is not suitable to my case. It is because I want several schemas in production database only.

[B]If you are going to export the entire data every day, then I would suggest that you look into that of doing incremental export. This would help you to save time a lot.

It didn't strike to me during my previous posting.
