Mirror site

A mirror site is a website or set of files on a computer server that has been copied to another computer server so that the site or files are available from more than one place. A mirror site has its own URL, but identical to the principal site. A mirror site is usually updated frequently to ensure it reflects the contents of the original site. This is mainly developed to handle the traffic of the original site so that the mirror site can ensure the better availability of the website and files.
