Backing Up DatabasesLocate this document in the navigation structure


Regularly back up your data and redo log entries from the data and log areas of your database to data carriers. No downtime is required for backups: you can execute backups in the ONLINE operational state, meaning that the database is available to users during backups.

Figure 1: Backing Up: Schematic Overview

If there is a database failure due to a hardware defect or a logical error, you can restore the database to a consistent state by importing the data and log entries from the backups. You can use backups you created on a Microsoft Windows system on Unix and Linux systems, and the other way round.


For backing up, use Database Studio, Database Manager CLI, or CCMS (in SAP systems only). Note that neither data exports created with the Loader database tool nor data area snapshots are data backups: they are not suitable for restoring a database.


Test your backup and restore process on a test computer before starting up your production system.

  4. Check if the database system carried out the backup successfully.

  5. If you use data carriers of the FILE type for log backups (backup files), then archive the backup files regularly.
