The name mentions a mirror for a reason, because the word "mirror" in the vocabulary of experts in Internet technologies has a similar application with a natural word. For example, a mirror is an object that reflects an image in front of it. This word has a similar definition in the environment of the Internet community, however, it is used in a phrase and in some other semantic understanding and reason for using it.
So, the phrase site mirror or portal mirror means two or more copies of the same site, which may contain full or partial content of the main site, which is called the main site mirror.
Why are they copying or “mirroring” sites?
There are many opinions on this, as the purposes of copying can be different.
But, one way or another, they combine into one goal - this is to ensure the safety of valuable content in the event of server problems . Just as prudent housewives lay out fragile eggs in different baskets, so prudent administrators and owners of web resources place mirrors of sites in different hosting. If the main portal fails or is blocked for any reason, the visitor is automatically redirected to the mirror portal.
This method of guaranteed content protection is especially common on slot machine sites such as, for example: http://online-slots-vulcan.com/zerkalo . The reason is not to lose the trust of regular customers, because if both the site and its visitors are blocked, gamblers (slot machine players) risk losing their winning funds.
Therefore, such sites make mirrored copies not only of the main content, but also of gamblers' access to their game profiles in order to protect the money accounts placed there in case they are blocked from accessing the main page of the site.
So that the mirror of a web resource is an original solution to the problem of its reliable protection from surprises, therefore, not only should you not blame the mirror, but, on the contrary, should be praised.
