      dockstar is a plug computer on the same lines as the pogoplug,
      guruplug, sheevaplug, etc. I bought three of them when they used to be
      $25 a pop, but that was a while ago. The pogoplug with wifi is around
      $50 at the usual places and can run openwrt... or even debian if you
      are willing to use an usb drive to put it in. So what I did on it in
      principle will work for all of them. I replaced the factory OS
      firmware with openwrt so now it is a standalone setup that cares
      nothing about their online service.

      Something like that should suffice to be a local backup. If you want,
      you can have it do some incremental backup to its local HD (hourly
      until filling the HD and then deleting the oldest? It is really up to
      you) and then to a remote location (amazon, a backup server you
      created and put in an undisclosed location once a day or thereabouts
      using some bandwidth throttling. Think this way: it has an entire day
      to do the remote backup dance.

      Honestly, even with disk level encryption the dockstar is not breaking a sweat.

      Power consumption is 10W max for my backup setup. This matters a lot to me.
