[ale] does DUMP backup only the 'used' HD fraction, OR, the 'entire' HD, blank space and all ?

[Jim Kinney]

dump ignores blank space. It's only concerned  with files.
Dump will not get the boot sector data.

The no label may just be a really old drive or a jumper is set wrong to
turn off LBA.

Note: it's not required for  full dump to reset the dump flags. You can
just ignore the flags with dump -level0

Master/slave: for performance needs, it;s best to have the source and
target drive on different ATA cables. If they share a cable as
master/slave, it will run at slightly less than 50% the dump speed as if
they were on different cables. It make no different which is master as long
as they are different if on the same cable.

I use rsync for this now. Dump is _so_ 1970's :-)

As long as the general population is passive, apathetic, diverted to
consumerism or hatred of the vulnerable, then the powerful can do as they
please, and those who survive will be left to contemplate the outcome.
