ChronoSync Backup software for Macs by Econ Products. It took me a bit to figure it out - but now I really like it. It can clone the Home Drive, backup multiple drives, and synchronize deletions. I've got it set to backup to drives on my Mac, a Drobo, and 2 sets of "foot modem" offsite drives (carried on foot to a neighbor's house). http://www.econtechnologies.com/chronosync/overview.html
