Your website is the digital storefront of your business, open to the public 24/7. If something happens that renders it inaccessible, then you’re losing potential customers. When your website is down, every minute that goes by is money lost. You can’t let this happen.
Quite a large number of users modify the files in the parent theme, and that often causes problems. After you update the theme to a new version, you’ll lose your changes and you’ll have to edit the files again.
Okay, we can all agree that it’s important to backup your website to prevent losing your data. After all, there are so many instances such as upgrading your theme, migrating your website data, hacking and security breaches, and more that can make your website vulnerable to losing data.
