I don't believe there are any back up/synchronize program with OS X (unless you are willing to use the Terminal and command line Unix commands); however, there are a number of programs available. LaCie has a free program Silverkeeper, which can be downloaded from their Web site. Commercial programs include Retrospect, Tri-backup, SuperDuper, and some others. I use Retrospect for my automated daily backups, and often use it or Tri-backup for less frequent, larger backups. Tri-Backup and SuperDuper can be downloaded and used in at least a limited extent before you pay for them; Retrospect must be bought before tried. >Hi everyone -- I appreciate all the help on this listserv.
