I have Snow Leopard installed on a USB drive in case something wrong happens during boot up of my mac mini, I can boot and work/get the files. Recently, this usb startup drive stoped working and I had to install OS X on it and update it all over again. So Im wondering, is it possible to make a backup of this startup usb disk on the cloud? I know I could have stored 2 diferent USB drives, but I would like the option of having it in the cloud and download to a new usb drive when needed. I know simply draging and copying the files wont work. What do I need to do? Crete an image? an Iso or DMG? I dont know what this things are or how to create them, so I would apreciate the knowledge. And more over, Once I redownload the file, how do I move over to the new USB? Is it using Disk Utility Restore?
