    Parameter

    Description

    Retention time limit

    Sets the automatic cleanup time for timed-out business data.

    Maximum threshold for data disk space

    Sets the maximum threshold for data disk space. When the disk space usage of the mount point where business data is located exceeds the threshold, an alarm will be triggered and data will be automatically cleaned up.

    Minimum threshold for data disk space

    Sets the minimum threshold for data disk space. When the disk space usage of the mount point where business data is located is below the threshold, data cleanup will be stopped.

    The cleanup based on timeout and the cleanup based on storage threshold are independent of each other, and either one can trigger automatic data cleanup.

  4. Click OK.
  5. Click to enable automatic cleanup.
