To guarantee the security and availability of the data in your database system, we recommend automatic log backups.
If automatic log backup is activated, a log segment of the log area is saved as soon as it has been filled. This log segment is then released again. This mechanism ensures that overflows in the log area are practically impossible.
We particularly recommend activating automatic log backups for all database instances where many changes are made to the data, leading to a high volume of logs. In this way, constant monitoring of the usage level of the log area is not necessary.
As long as automatic log backup is active, you cannot start an interactive log backup. However, you can perform a data backup at the same time.
You can only perform automatic log backups in the operational state ONLINE.
In the case of an automatic log backup, you can only use version files as the backup medium
