TwitBak is an open source (LGPL) backup client for Twitter built on Java. Download TwitBak.jar to get started.

If your system doesn't know what to do with this file, you might not have the Java Runtime Environment (JRE) installed. You can download it here: http://www.java.com/en/download/manual.jsp

As of the current preview release (0.1a), TwitBak backs up user data, statuses, direct messages, favorites, and mentions (aka @-replies). The output is stored as JSON in a plain text file.

Twitter has placed a temporary retrieval limit on statuses, so only the last 3,200 are available (see http://apiwiki.twitter.com/Things-Every-Developer-Should-Know ). When this limit is lifted, TwitBak will automatically adjust.
