RMAN versus EXPORT Incremental backups (Doc ID 123146.1)

Last updated on OCTOBER 25, 2023

Applies to:

Oracle Database - Enterprise Edition - Version 8.1.6.0 and later
Oracle Database Cloud Schema Service - Version N/A and later
Gen 1 Exadata Cloud at Customer (Oracle Exadata Database Cloud Machine) - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Oracle Database Cloud Exadata Service - Version N/A and later
Information in this document applies to any platform.

Purpose

The following documentation announces the obsolescence of the incremental exports:

1. "Oracle8i Utilities Release 2 (8.1.6)" (which is included as such in "Oracle Documentation Library, Release 8.1.7") says:

   Incremental, Cumulative, and Complete Exports

   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.


2. The note: 120608.1 "[8.1.7.0] Generic Server README for Oracle8i Release 3"   says:

   5.2.3 Incremental, Cumulative, and Complete Features No Longer Supported Incremental, cumulative, and complete Exports are obsolete features. They are no longer documented, nor is their use supported by Oracle Corporation.

RMAN incremental backup is the only corresponding feature to replace the EXPORT incremental backup.
This document describes the differences between both.

Scope

For those DBAs that use EXPORT incremental backups, the document illustrates the points they should be aware of when migrating from EXPORT incremental backups strategy towards RMAN incremental backups.
