Archive (ON-Archive and ontape) (SAP Library - SAP Database Guide: Informix (BC-DB-INF-DBA))

Archive (ON-Archive and ontape)

Purpose

You can archive your Informix database using the Informix tools ON-Archive or ontape . For more information, see Informix Archive.

Note

If you are using ON-Bar , the term archive has been replaced by "whole-system backup" and "storage space backup". Refer to Informix Whole-System and Storage-Space Backups.

An archive with ON-Archive or ontape is similar to a whole-system or storage-space backup with ON-Bar . For more information about backups with ON-Bar , see Database Backup (ON-Bar).

Prerequisites

You have decided which tool you are going to use for archive ( ON-Archive or ontape ) or database backup ( ON-Bar ). Refer to Comparison of ON-Bar, ON-Archive, and ontape for Data Recovery.

Caution

You must use the same tool for logical-log backup as you do for database backup or archive. You cannot use different tools because the data produced is not compatible.

You have completed the preparations for archive with your chosen tool:

Configuration of ON-Archive
