WGET is Ultimate Downloader . While you can use it simply to retrieve a single file from a server, it is much more powerful than that and offers many more features.One of its features is mirroring website.

The basic command to mirror website is $ wget -m http://www.example.com This command will allow you to download website but it can't make a complete local copy of a website. This command only download the page but the links still point to the real URLs including the images and stylesheets. We have to add another option to make links not point to real URLs. Add option -k after -m $ wget -m -k http://www.example.com Now, the links will point to next page in our local copy website. To delay your download, you can add option -w and how much time that you want to delay it. Because if we delay the mirroring, it can reduce the load
