Research direction

Start with iotdb-client/.../org/apache/iotdb/tool/backup/IoTDBDataBackTool.java and review the SonarCloud findings listed in the issue. Update the logger class, field naming, and empty-string check consistently throughout the file, then verify the backup tool still builds and behaves without functional changes.

Description

Description

This task focuses on resolving multiple SonarCloud issues identified in backup/IoTDBDataBackTool.java.The file currently contains several maintainability and code quality violations, including:

  • Update this logger to use "IoTDBDataBackTool.class".
  • Rename this field "IS_OBJECT_STORAGE" to match the regular expression '^[a-z][a-zA-Z0-9]*$'.
  • Use "isEmpty()" to check whether a "String" is empty or not.
