When adding folders you select the source and destination folder, select if you want to include subdirectories in the backup, schedule the backup (minutely, hourly, daily, weekly and monthly), define if you want to start the backup after startup or at a given time and choose if you want to overwrite all existing files or only those that have been changed.

If you plan on using Everyday Auto Backup you should keep the setting that starts it during Windows startup. I would suggest that you disable it if you only plan to use it sporadically.

This is a great backup utility even for inexperienced users who do not like to think about stuff like backing up system files or personal ones.
