The Internet Archive is a non-profit digital library with the stated mission/motto: "universal access to all knowledge". The Internet Archive stores over 400 billion webpages from different dates and times for historical purposes that are available through the Wayback Machine, arguably an archivist's wet dream. The Archive.org website also archives books, music, videos, and software.
There are currently two mirrors of the Internet Archive collection - the official mirror available at archive.org, and a second mirror at Bibliotheca Alexandrina. Both seem to be up and stable.

Uploading to archive.org
Upload any content you manage to preserve! Registering takes a minute.
- For quick one-shot webpage archiving, use the Wayback Machine's "Save Page Now" tool.
- S3 interface (for direct usage with curl, or indirect with the tool of your choice.)
- internetarchive Python tool is one such tool.
- Handy script for mass upload with automatic error checking and retry.
- Torrent upload, useful if you need resume (for huge files or because your bandwidth is insufficient for upload in one go):
- Just create the item, make a torrent with your files in it, name it like the item, and upload it to the item.
- archive.org will connect to you and other peers via a Transmission daemon and keep downloading all the contents till done;
- For a command line tool you can use e.g. mktorrent or buildtorrent, example:
mktorrent -a udp://tracker.publicbt.com:80/announce -a udp://tracker.openbittorrent.com:80 -a udp://tracker.ccc.de:80 -a udp://tracker.istole.it:80 -a http://tracker.publicbt.com:80/announce -a http://tracker.openbittorrent.com/announce "DIRECTORYTOUPLOAD";
- You can then seed the torrent with one of the many graphical clients (e.g. Transmission) or on the command line (Transmission and rtorrent are the most popular; btdownloadcurses reportedly doesn't work with udp trackers.)
- archive.org will stop the download if the torrent stalls for some time and add a file to your item called "resume.tar.gz", which contains whatever data was downloaded. To resume, delete the empty file called
IDENTIFIER_torrent.txt; then, resume the download by re-deriving the item (you can do that from the Item Manager.) Make sure that there are online peers with the data before re-deriving and don't delete the torrent file from the item.
Don't use FTP upload, try to keep your items below 400 GiB size, add plenty of metadata.
Formats: anything, but:
- Sites should be uploaded in WARC format;
- Audio, video, books and other prints are supported from a number of formats;
- For .tar and .zip files archive.org offers an online browser to search and download the specific files one needs, so you probably want to use either unless you have good reasons (e.g. if 7z or bzip2 reduce the size tenfold).
This unofficial documentation page explains various of the special files found in every item.
Downloading from archive.org
- Wayback Machine APIs
- internetarchive Python tool
- Manually, from an individual item: click "HTTPS"; or replace
downloadin the URL and reload. This will take you to a page with a link to download a ZIP containing the original files and metadata.
- In bulk: see http://blog.archive.org/2012/04/26/downloading-in-bulk-using-wget/
- There's also an unofficial shell function that checks how many URLs the Wayback Machine lists for a domain name.
Backing up the Internet Archive
A discussion has begun about creating a distributed backup of the content of the Internet Archive. This is currently in the planning/testing phase. For the initial manifesto, see the INTERNETARCHIVE.BAK page, for the records of the brainstorming, see its talk page, and to follow the discussion in real-time, join the #internetarchive.bak IRC channel on EFNet.
UPDATE: The git-annex implementation is now testable and started with archiving some collections of the Archive. If you have a few hundred gigabytes of spare space (that you are willing to sacfirice for a long time), ArchiveTeam counts on your contribution.
Let us clarify once again: ArchiveTeam is not the Internet Archive. This "backing up the Internet Archive" project, just like all the other website-rescuing ArchiveTeam projects are not ordered, asked for, organized or supported by the Internet Archive, nor are the ArchiveTeam members the employees of the Internet Archive (except a few ones). Besides accepting – and, in this case, providing – the content, the Internet Archive doesn't collaborate with the ArchiveTeam.
