Auto directory backup daemon for Linux - based systems. Makes a backup copy of any file created, modified, moved-to the --dir directory, to --bak directory (with .bak extension).

Allowed args:

-h [ --help ]         show help
-v [ --version ]      show version
-D [ --debug ]        enable debug logging
-s [ --silent ]       disable console log
-d [ --dir ] arg      directory to monitor
-b [ --bak ] arg      directory to create backups to
-l [ --log ] arg      log file path

Note:

1. Files that are inside of monitored, prior to application launch, won't be backed-up.
2. Directories, hidden files (with filename .name.ext), irregular files (links, devices) are ignored.
3. Files prefixed with delete_ will be deleted immediately, their corresponding file (w/o prefix) will be deleted too, as well as the backed-up file.
4. Files prefixed with delete_ISODATETIME_ (e.g. delete_2021-07-30T12:13:14_) will be deleted at specified time (if, of course, that time is in future).
