*Enable file system backend*

Type: ``bool``

Help
====

.. code-block:: none

    When enabled, backend is using the configured file system to output logs.
    As the file system must be mounted for the logging to work, it must be
    either configured for auto-mount or manually mounted by the application.
    Log messages are discarded as long as the file system is not mounted.
