Original question was what is the best way to duplicate an external system
disk so that in the event of a system disk failure, the backup disk can be
used to replace the crashed system disk rather than restore from a 0 level
dump tape.

The overwhelming response indicates that dd is the way to go:

     i.e.; - reboot in single user mode
          - disklabel -z rzYY (target disk)
          - dd if=/dev/rrzXXc of=/dev/rrzYYc bs=2048k
