Twackup -- Back up your tweets easily

Builds like any other Go package.

Runs like:

twackup USERNAME DIRECTORY

twackup will write tweets, as JSON, under the given directory. The file name will be the tweet id.

Downloading is fully incremental; twackup will look for both newer and older tweets than the ones the directory already has. Note that this won't re-download tweets in the middle, if they are deleted from the directory.
