Recovery with Informix
To minimize downtime with your Informix database, you must make sure that you can quickly recover the database in the event of a failure with loss of production data. With Informix, recovering the database includes routinely backing up the database and restoring the database after a failure. This section concentrates on database restore. For more information, see
Informix provides the following
tools for database recovery (including restore):
ON-Bar (the most recent tool) together with a storage manager such as the Informix Storage Manager (ISM)
When ON-Bar was released, Informix changed the terminology to bring it into line with other databases. The term "archive" from ON-Archive and ontape is no longer used with ON-Bar . Instead, "database backup" is used.
In this section, we use "database backup" to include the term "archive".
You make sure that you have suitable and recent database and logical-log backups. This is absolutely essential if you want an up-to-date restore of the database. Refer to Backup with Informix.
You work out a recovery strategy, including an approach to database restore.
You test database restore using a test system as similar as possible to your production system.
You can restore your database as quickly and efficiently as possible, so avoiding downtime caused by a failure with loss of database data.
