debra states "there are NO backup programs that can restore the disk to the state
it was at the time of the backup since this is simply not possible in Unix."

this is of course only true if the backup programs restore as a user-level program.
as an obvious example, dump doesn't cause the access times to be updated.
but then again, with the modern trend of more complicated file systems continuing,
no one can write these disk-level programs any more anyhow.
