По умолчанию Performance Evaluation of Web Archiving Tools.

Archiving the websites in their entirety is a difficult task and it needs both good mirroring and spidering techniques. Open source website archiving tools that are available are not able to completely search and down load some of the web pages and images. The main objective of this study and analysis is to develop a comprehensive website archiving tool that re-creates the site completely and useful for offline browsing. In this paper, the performance evaluation of open source website archiving tools like, HTTrack and cURL , based on certain objective unit tests has been done and a study has been conducted to compare the basic drawbacks of different archiving tools. As the WWW keeps growing at an incredible rate day by day , complete mirroring of a complex website is very difficult, and entails the same logic (reading HTML, Java script and Flash) that browsers use[1]. Spidering and collecting links and text is simple by comparison. Accurate archiving imposes unique needs, which requires spidering to be comprehensive and mirroring highly accurate. Most spidering tools lacked good basic mirroring ability. Very few searched .js or .css files for links, parsed those pages and followed what browsers and web users see as obvious links. Many did not download images, but relied on live original sites to feed these images to the archive viewer.
