Data dumps
(Redirected from Dumps)
The Wikimedia Foundation is requesting help to ensure that as many copies as possible are available of all Wikimedia database dumps. Please volunteer to host a mirror if you have access to sufficient storage and bandwidth.
About Wikimedia Dumps
Wikimedia provides public dumps of our wikis' content and of related data such as search indexes and short URL mappings. The dumps are used by researchers and in offline reader projects, for archiving, for bot editing of the wikis, and for provision of the data in an easily queryable format, among other things. The dumps are free to download and reuse.
Note that the data dumps are not backups, not consistent, and not complete. They are still useful even so.
