The way I normally do this is:
find <directory to copy> -print | cpio -pdumv <where to copy files>

I just recently wrote a custom script that "mirrors" two drives each night.
It starts by 'dd'ing the mbr and the /boot partition, then mounting the "/" and
"/var" partions on the secondary drive, use mirrordir to sync up the files,
then unmount everything on the second drive when finished. Useing dd for the
mbr and /boot partition keeps lilo synced up on both drives, and makes sure
that the kernel is in the same physical place on the second drive. Of course
this requires that boths drives are physically the same.
