      ### NOTICE ###
      As part of restore, the task tried to rename `#{path}` before restoring.
      This could not be completed, perhaps `#{path}` is a mountpoint?

      To complete the restore, please move the contents of `#{path}` to a
      different location and run the restore task again.
