Backing Up the Database Contents<br />

Lesson Duration: 30 minutes<br />

Lesson Overview<br />

This lesson will deal with basic concepts for backing up the database.<br />

These include regular backups of data and log information. These backups<br />

are performed with the database planning calendar (transaction DB13).<br />

Lesson Objectives<br />

After completing this lesson, you will be able to:<br />

• Back up the contents of the database<br />

• Check whether your database backups have been successfully<br />

performed<br />

In particular, you should emphasize in this lesson that a successful<br />

database backup always includes a backup of the log information. If an<br />

error occurs, it is only with the log information that the database can be<br />

restored without data loss.<br />

Business Example<br />

To protect the <strong>SAP</strong> system against data loss if an error occurs, the<br />

administrator regularly performs backups.<br />

Backup Concept<br />

A backup concept for the database always includes the regular backup of<br />

the data files, the structure data, and also the log information.<br />

The backup of the data files and the log information is performed in<br />

different steps. All data files and the structure data are backed up in one<br />

step. In another step, the ongoing log information (this may include the<br />

structure data) is backed up separately.<br />
