DB Log Export

Supports exporting log data that requires long-term retention among audit logs to Object Storage. Users can directly configure the log types to be stored, the target bucket for export, and the export interval. Based on the configured criteria, logs are copied to the specified Object Storage for retention. Additionally, to efficiently manage disk space, we provide an option that exports logs to Object Storage while automatically deleting the original log files. By using this option, you can effectively free up storage capacity while safely retaining the necessary log data for long-term archiving.

Information
  • To use the DB Log export feature, you must create an Object Storage. For creating an Object Storage, please refer to the Object Storage User Guide.
  • Please be sure to check the expiration date and time of the authentication key. If the authentication key expires, logs will not be stored in the bucket.
  • Please ensure that authentication key information is not exposed externally.
