     4  Shellflow automatically backup small input/output files. If a size of
     5  file is smaller than 20MB, the file will be compressed with gzip and
     6  backuped to ``shellflow-wf/__backup``. Shellflow rename filename with
     7  SHA256 hash result. Currently no method to investigate backup file name
     8  expect reading log file directly.
