  • The University of Toronto has a GitHub organization with some tools you might find useful for mirroring data in an archivable format.
  • The Internet Archive also offers Brozzler as a tool for crawling and archiving sites.
  • Web Recorder lets you create verifiable web archive files for submission to the Internet Archive or hosting on your own.
