Hi Nemo. It is a great idea, but it needs a lot of resources (space and bandwidth).
By the way, MediaWiki includes dumpBackup.php to make wiki backups. But people do not use it, and do not publish backups. If we make an extension or feature (disabled by deault), it is the same problem. Only a few persons are going to care about enable it and publishing backups.

We know that websites are fragile and that broken links are common. Wikimedia (and other communities like Wikia) publish dumps of their wikis, but, that is not common. Most wiki communities don't publish any backups [...]
Would it make sense to add a feature to MediaWiki 8disabled by default) that makes the regular generation of dumps automatic and creates some special page to access them or even sends them to some central repository (we could create one for free license projects)? So people wouldn't need to care about dumps and we wouldn't need to go around looking for wikis.
