It's worth at least a look.  It is pretty nice to run 'as is' to have
a quick bare-metal restore if you know you are going to do something
risky, or to move to different hardware or a VM. But, I think it has
exactly the parts that backuppc is missing in terms of bare metal
rebuilds and since it is all native tools and shell scripts a small
amount of tweaking could give the advantages of taking next to no
extra backup space as pooled on a backuppc server and also always
having current version-matched filesystem tools on your bootable
restore image.

All you need to try it out is some writable nfs space for it to write
its iso and tar images.  And if you can map that iso image file into a
VM,  you don't even have to touch anything to go through the motions
of the restore.
