I've lost the internatl drive in my PB for the second time in three months (an 80gig 5400). It's really distressing when you're based in a country with not a single Apple Authorized repair centre and thus even a warranty fix means getting on a plane. Anyway - that's not what I want to talk about (I was venting). I'd like to know what people reccomend as back-up software for OS X (is CCC the only suggestion or truly the best?) Also any tips for preserving a drive in a computer that's used 12 hrs a day? I already have 1TB of external drives and have just ordered another 500GB. I use the externals for the heavy lifting but the internals are in use (browsing, IS, PS etc) all day. Faced with a possible loss of data (yes I back up - no I didn't do it every day) I don't mind spending money for security. Suggestions please.
