I am going to upload a working version including restore functionality
of hubackup soon enough to feisty, and we could certainly use it already
to allow users to backup from the snapshot LV. True, hubackup doesn't
yet support back-ups to network targets, and we're still in short of a
working default set up of LVM in Ubuntu. Regardless it would be
interesting to explore how we can use arnie as a back-end for storing
backup to network locations in hubackup.

Feels to me like duplicating what LVM can do already in a tested manner
- if we were already going to GUI wrap the LVM tools or to combine
between another set of UI and back end tools, we might as well add UI
functionality to initialize an external device (USB disk or whatever) to
act as a snapshot volume, as I also believe using an /external/ device
to store the snapshots will provide better recoverability.
