Wow... pretty interesting but seems not ready for prime time just yet.

Are you using it?... If you scroll down the page a ways you find that
the author has been yet gotten things working in the case of failure
and in his words:

  Finally, I'm trying hard to do the right thing in the face of
  failure. The service will move to maintenance should a backup fail
  for any reason, and the cron job should be removed in that case

Where as if it were just a simple cron job running a less grand scheme
it would just run again next time... so in the case of things like
momentary los of network or whatever the job wouldn't get retired
completely. 

I was thinking more of plain scripting and cron.  I can do that my
self but it will take `some' amount of time.  I just thought maybe
someone else had done something I could use and change for my usage. 

However the work you pointed too looks like it will be a very nice
tool once some of the wrinkles are ironed out.
