If a hardware problem or other error occurs, you return your database to a consistent state (restore) using backups. To speed up the backup process, you can back up data to several data carriers in parallel.

Recommendation Recommendation

Regularly back up the data from your database to data carriers.

Use parallel backups whenever possible.

End of the recommendation.

Prerequisites

Recommendation Recommendation

Check the database structures of your database before carrying out a complete data backup.

More information: Checking Database Structures

End of the recommendation.

  • You are logged on to the database as the database system administrator or as a DBM operator with server authorization for performing backups.

    More information: Glossary, Server Permission

  • You have created a backup template.

    If you want to backup to several data carriers in parallel, you need a backup template for parallel backups.

    More information: Defining Backup Templates

  • The database is in the ONLINE or ADMIN operational state.

  • If you are using a third-party backup tool, connect it.

    More information: Installation Manual, Connecting Third-Party Backup Tools

  • Only on Microsoft Windows:

    If you want to back up data to a data carrier on a remote computer, perform the steps described in Database Administration, Backing Up and Restoring Data with Remote Computers.

Note Note

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

End of the note.
