MediaWiki/backing up

About

The two main pieces of MediaWiki which need to be preserved in order to reconstruct a site in the event of drive failure are:

• custom files:
  • the images folder (which I usually rename to "wikiup", to distinguish it from "images" folders created by other apps)
  • any customized artwork created for the site (probably preserved elsewhere, but it's a good idea to keep everything together)
• the database
  • exact process depends on what engine you are using
    • for MySQL: MySQL/migration
