My lp:rye/duplicity/mediafire branch was merged. And this means that MediaFire backend will be available for general public when the next duplicity version is released.

I had to change a couple of things in order for it to be accepted, so here's how to use the new built-in mediafire backend.

All the warnings from my original article still stand, so read that first before you sign up for the service.

First, install the mediafire library:

pip install 'mediafire>=0.5.2'

0.5.2 is the latest release as of now. If you use pip, you'll get the latest version.

Define your password in FTP_PASSWORD variable. Yep, I know, it's counter-intuitive, but that variable is used by multiple backends already and having the new backend playing well with others is also important:

export FTP_PASSWORD=your-mediafire-password

Set the remote URL as: mf://your-email%40example.com@mediafire.com/path/to/folder.

Frankly speaking, it does not matter what domain you are using as the mf protocol handler will kick in, but the parser is really really interested to have a fully qualified domain. Try mf://email%40example.com@mfi.re/path/to/folder to save some keystrokes. Your email must be URL-encoded.

Well, that's really it.
