This is a good solution if the drive you're mirroring to is *exactly the
same* as the disk you're mirroring from. If the physical geometry of each
drive does not match identically (one is a 2g quantum and the other a 4g
IBM, for instance) and you mirror the smaller drive on the larger drive /w
dd, the larger drive will show as a 2g unit. If you don't have same size
disks, use tar, as root:
tar cvf - / | ssh -l root <remote host> tar xvf -
(assuming you're going from one machine to another)
If you're mirroring to a local disk, you can generate the appropriate
command line to untar the filestream on the other disk.
