Imagine the situation: you are creating a website. You hire a webmaster or do it yourself, spending a lot of money and personal time on it. You host your brainchild on hosting and you fill it with information, without thinking about that you need to keep a copy of the site, so as not to lose data.
One day, not very good for you, yougo to your site, and it does not work. You start to find out what's wrong, and, horror, the data center has burned down or hosting has flown. Or maybe you got a virus and destroyed the data. The loss of information on the site is comparable to the loss of information on the computer. So how do you keep a copy of the site?
Let's look at the definition first. The process of archiving websites - is to keep the current version of the page or site in the archive for later work with it. For these purposes, specialized software is used. The largest company in the world is the Internet Archive, which we'll talk about below.

You can save the site to your computer usingFTP client. If you use the program FileZilla, then create a folder on your computer "Backup" (the folder name can be anything). Connect to the server via FTP-client and by simple drag and drop make a full backup of the site in the folder "Backup".
In addition, you can use the serviceSite2ZIP (site in the archive), the program for downloading WinHTTrack WebSite Copier. How can I see a saved copy of the site? To do this, open the folder in which the site was saved, and click on the index.html file.

If you are wondering how to opena saved copy of the site, go to archive.org/web/ and enter the address of the site or page in the corresponding field.

A saved copy of the Google site is nothing more than a "as the cache of the pages of the site, which was made by the search engine. Any user at any time can use for their needs a copy of the page. Saving them on the servers of search engines takes a lot of resources, and for this purpose a lot of money is allocated, but this help pays for itself, since we still go to search engines.
