This looks nice, but very similar to a bunch of existing projects like <a href="http://www.celeryproject.org/" rel="nofollow">http://www.celeryproject.org/</a> Are there any clear differentiators?<p>Also, I understand it's a new project, but some more documentation would be helpful. E.g., how does one backup and restore the tasks and settings? Does it provide alerting when a job fails?
