Create a backup zip of your content and settings with a single click that can be used to restore your site quickly and easily.
My biggest problem is that you can't schedule backups. No good. Second problem, backups take too long, I don't have the time to watch this, especially if you can't schedule it in the background.
But it is very simple. You don't need to know anything about where files or located or which should or shouldn't be backed up. But overkill on simplicity. There are much better out there.
