I have 10.4 but I think this is a general question. Right now my Ipod is bigger than the drive in my computer. If I were to copy my whole drive, or just my user directory, onto an encrypted disk image and put that on my Ipod, would it be pretty secure? I was thinking it would be an extra backup, and if the La Palma tsunami or some other disaster struck, I could just grab my Ipod, and I'd have all my most important data. What do you think? I'd want to be sure though that the encryption is secure so someone wouldn't have my stuff if they stole the Ipod or I lost it.
