[RndTbl] disk cloning

I am trying to find a good backup method for my Mac hard drives.
For Windoze, I discovered that the best method was to boot to a Fedora
Core rescue CD, and use the dd command to block copy a disk or
partition from one [removable] drive to another.
On my Mac, I am switching to an alternate boot drive so that I can
copy my usual boot drive to a third drive using the dd command from
the Terminal. However, I am encountering an IO error, and there are
differences between the original and the copy as shown using FileMerge.
Carbon Copy Cloner failed to complete the task after encountering an
IO error. At present, I can't get it to work at all.
On a Unix based system such as the Mac, should file level copies be
adequate? This clearly did not work in Windoze - it seemed that
hidden files wouldn't copy, and/or references in the target partition
would still point to items in the source partition.
Any suggestions re how to make a clone of my boot drive would be
appreciated.
