Enabling the Automatic Log Backup Policy

Function

CSS provides log query and log backup, enabling you to easily manage and analyze logs to efficiently locate faults, optimize performance, and enhance system security.

  • Log query: On the log management page of the CSS management console, you can query the latest 10,000 log records by node type and other criteria. A maximum of 100 results are displayed, enabling you to quickly locate issues.

  • Log backup: Cluster logs are periodically synchronized to OBS buckets. You can download them for in-depth analysis at any time. You can configure custom log backup policies by specifying backup schedules and storage locations. The system backs up all critical logs, including run logs and deprecation logs. They provide comprehensive data for auditing and troubleshooting purposes.

This API is used to enable an automatic log backup policy. If log backup is enabled for a cluster, you can use this API to configure an automatic backup policy to periodically back up cluster logs to a specified OBS bucket and directory.
