What is the Wayback Machine

In 2001, there occurred a problem when website contents vanished immediately after the page gets changed or shut down. This problem has been solved after the launched of Wayback Machine by archiving web pages in a three-dimensional index.

With the development of technology, the Wayback Machine’s storage capacity has been grown up as now websites can be stored manually. When a website’s URL is entered on the search box of the machine, it automatically crawls it and captures it and there is also a ‘Save Page Now’ button.

The Wayback Machine was launched with 10 billion archived pages in 2001 but it has contained over 25 petabytes of data in 2018. At present days, a large cluster of Linux node by Internet Archive is using to archive data.

How Does it Work

The Wayback Machine usually archives a webpage by using some spidering or web crawling software. The Alexa program, a toolbar on the computer provides a Website domain when the web crawling software identifies it. After that, the contents are cataloged and retrieved and thus archived as a webpage.

The process of archiving pages follows specific criteria, but it does not mean everything gets permission to be recorded on the Wayback Machine. Some domains cannot save its content by recording a “no crawl” message instead of its archive snapshots. Usually, contents of websites get stored as HTML files or captured snapshots or related external files like image files.

Missing contents of a specific website can be recovered in the Wayback Machine as it can substitute them by linking similar content to the other sources. But this is not always happened, in some cases, the machine doesn’t display anything for missing contents or may show blank pages.

Sometimes this breaks hyperlinks and removes images. Web crawler doesn’t permit to save progressive web application also because they need a link with the host website.
