Why are updates and backups important?

Security breaches are a constant problem to the modern website as intellectual property increases in value. If the core and plugin files are not regularly updated they are more susceptible to these attacks and WordPress sites can be left wide open. Furthermore, outdated WordPress sites can stop working of their own volition. Backups keep a solid copy of the site in case there is such a problem. If there is a breach or system failure, the backup can restore the website to functionality.
