The NetarchiveSuite is a complete web archiving software package developed from 2004 and onwards. The primary function of the NetarchiveSuite is to plan, schedule and run web harvests of parts of the Internet. It scales to a wide range of tasks, from small, thematic harvests (e.g. related to special events, or special domains) to harvesting and archiving the content of an entire national domain. The software has built-in bit preservation functionality. The systems architecture allows for the software to be distributed among several machines, possibly on more than one geographical location. The NetarchiveSuite is built around the Heritrix web crawler, which it uses to harvest the web.
