Through a bit of idiocy, I lost the original discs to some of my applications. As a result those apps only live on my iBook HDD. Should that HDD for any reason collapse, I'll be sol ... so, I decided that I need to back up my HDD just in case something goes wrong. So, I'll use Carbon Copy Cloner (CCC) to back up my 40GB iBook HDD to an external 300GB Seagate with firewire. In the CCC documentation, it says: "Mounted disk image. Cloning to a disk image will (obviously), not yield a bootable volume unless you use CCC to restore the image to a physical partition or disk." There are two options in CCC: I can clone my iBook HDD to 1) Disc Image or 2)Bootable Drive. I'm a bit unclear here. Which should I select, if my main aim is to make shure that if my iBook HDD bites the dust, I still have my apps available? And by "available" I mean that I'll be able to take the backup from the external Seagate and put it on a new notebook drive that I can pop into my iBook, and all the apps will work as they do now on my original HDD. Thanks!
