I've been using Disk Utility to make my HDD backups for some time now. I'll plug in a large HDD, start disk utility, create an image of any drive i want to backup, save it compressed (default settings) to the larger drive, then unplug the larger drive and physically store it elsewhere. All that has been going great. I can mount the images and they are good backups. But what if I want to use them to restore a drive? Here's where the problem comes in. I plug in my large drive with the images, use Lion's recovery boot, go into disk utility, clear the main OS drive, and use the image file from the large HD to restore the image to the main OS drive. However, i have not been successful yet. I keep getting errors like "resource busy" or "internal error". Is this not something disk utility can do? If im buying a new system and I want to be able to restore an identical copy of my drive to a new HD, should I just use superduper instead? Im confused. Any help appreciated.
