No, I haven't tried that. I have used two methods:

1. Carbon Copy Cloner <http://www.bombich.com/software/ccc.html>

Fast and efficient, makes bootable copies, but can't do incremental backups
without installing additional software (psync).

2. The "ditto" command

A built-in command line tool that can be scheduled and which handles
resource forks correctly. However, it can't do incremental backups. Thanks a
*LOT* Apple. Smart.

Example: ditto --rsrc /Volumes/internaldrive /Volumes/externaldrive

I am looking into xtar, a version of tar that can handle resource forks,
which I'm told comes standard with 10.4, and rsync:
