The appropriate frequency of backups on your site will depend entirely on the nature of the site and how often new content appears. If you run a blog where you post a new article once per week, there is no reason to run daily updates — nothing will have changed from one day to the next. Instead, you’d want to run weekly updates that occur shortly after the new post has gone live. Customize your scheduling to match up with the way your site operates to get the most value and protection out of your backup plan.
