Hi all. Love this forum. Need ideas: I have 30 iMac's, none older than 3 years. 3 classes of film students and their projects that need backup. Snow Leopard. Firewire 800. I am concerned about price and security. If possible I would wish for a secure enclosure and drive for $100.00 each. Might have to scrub the idea of security, where to begin? Thanks..
