Apple has a fantastic, integrated, hands off software/hardware solution for backup. The software is called Time Machine and it is amazingly simple to use with a beautiful user interface. The hardware Apple sells to store the backups on is called Time Capsule. Today I bought my wife a Time Capsule to serve as backup storage for her MacBook. I didn't do quite enough research before buying. I have discovered a web site called http://timecapsuledead.org/ where you will find a database of thousands of users whose Time Capsules have died from overheating after an average of 18 months. Poor design for heat removal seems to be the problem. In a forum located here on Apple's site you will find an incredible history of frustrated users discussing the death of their units. Apple so far has refused to acknowledge the problem.
Here is a link to the product page on Apple's web site where they say "you never have to worry about backing up again" and "Its massive 1TB or 2TB server-grade hard drive". Server grade? I don't think so. I ran a data center that had REAL server grade hardware and this stuff would be laughed out of the room. Come on Apple, acknowledge the problem and FIX IT!
We bought our unit at Best Buy to be shipped directly to our house. I won't even take it out of the packaging - I'm returning it to Best Buy as soon as it arrives.
