Bit Image Copy of HD

[Jack Rodgers]

I was just thinking about backups and the problems encountered with OS 
X and why vendors have run into problems making an OS X backup.

I recalled a technique where a copy of the drive would be made to 
another not by copying individual files but by copying the entire drive 
bit by bit. Forget the name of the technique.

I then wondered if this could be used for OS X and whether it would be 
simpler and faster. Retrospect Express takes an awful long time 
gathering the file and folder info, comparing, erasing, etc. plus 
whatever it has to do to maintain the OS X file system.

If making a bit by bit copy of the drive is possible, then the software 
wouldn't have to work in OS X, I would assume. Are there other problems 
involved that would prevent this technique from working?
