That looks like a one-off kind of tool.  Backuppc/amanda/backula are
all frameworks to manage potentially large numbers of targets.

Another interesting thing is Relax and Recover
(http://rear.sourceforge.net/ - in EPEL as rear).  This is something
that you run on a working system to generate a bootable iso with that
system's own tools to reconstruct the current filesystem layout
(including LVM/md raid, etc.) and restore a backup onto it.  It
includes a few backup methods internally but with a small amount of
work you could integrate your own backup approach into it to get a
fully-scripted bare metal restore.
