You don't always think about needing security, when your website is new but you do need to protect your investment and yourself. Having a site go down and not see this page being able to restore it quickly may mean a loss of customers who probably won't remember to search for your website again later and can not find you. Don't let that happen to you. Back your site up after you get it started, as the site is operational and schedule backups for as long. This way, you'll have WordPress security and peace of mind.
