Function documentation Backing Up Data Locate the document in the library structure

Use

The database system stores the data in the database in the data area. If the data area has been damaged, for example due to a hard disk error, you need data backups to restore the data area. Therefore, you should regularly back up your data on backup media.

You can perform data backups in the ONLINE operational state.

Note

In addition to the data backups, you may need backed-up log entries to restore the database instance to the desired state following damage to the data area (see Backing Up Log Entries).

Types of Data Backups

Name

Description

Complete data backup

You back up the entire data area.

Incremental data backup

You back up all data in the data area that has been changed since the last complete backup.

Prerequisites

·        You have created a backup medium. See Backup Media.

·        The database instance is the ONLINE or the ADMIN operational state.

Activities

Note

You cannot start an incremental data backup during a complete data backup.

To back up data, use the Database Manager database tool, or the CCMS in SAP systems. See:
