This is just a physical media dump, which operates regardless of partition
state.  I think you'll find this is a $36 version of dump(8), dd(1),
gzip(1), etc...     Not that the convienance of the tools spiffy graphical
interface isn't worth $36... it may be, to have easy backups and reinstalls.

Like any low level copy, it is *not * a good idea to run it against a
mounted filesystem.  Bits will be in inconsistant states, depending on when
they are grabbed by the program.  So, with this software, I'm almost
certian you'll have to reboot with some kind of boot disk they provide, and
image the disk with the system offline.  Fine for home box, unacceptable for
most servers.
