href=\"https:\/\/www.techopedia.com\/definition\/29023\/web-hosting\">hosting<\/a> the original website on another server. This process, called mirroring, uses data replication and <a href=\"https:\/\/www.techopedia.com\/definition\/1006\/data-synchronization\">synchronization<\/a> to ensure the mirror site matches the main website. During mirroring, data is sent to the mirror server, which stores the same files, content, and structure as the original.<\/p>\n<p><strong>Synchronization<\/strong> keeps the mirror site updated with any changes made to the main website.
