Backblaze is designed to be used with absolutely no configuration (for many users they have no idea where their Outlook.pst file is and we don't think they should have to know), and the only way we could figure out how to make this work was to backup EVERYTHING on your system unless you explicitly exclude it. So bzinfo.xml is basically a flat list of excluded folders you do not want backed up. There is also a throttle in there if you don't want Backblaze to utterly destroy your network uplink, and a few other small settings. It's pretty straightforward.

With that said, we really pride ourselves on easy to use software, so it goes against everything in our DNA to release software with NO GUI at all, but maybe we'll give that a serious thought. If you are using Linux, you probably aren't the average Mom & Pop user. :-)

Call it alpha, see how much demand there is, and the extra money you bring in might be the motivation to finish up the pretty. :)

I just want to join others asking here for a Linux version. Please do release whatever you have. And actually I would prefer a command line tool, so I can use it in my cron.
