I'm already using a Disc Imaging program, but have to use DVD's all the time. Would like to get away from having to use DVD's. Someone told me about Acronis, and I thought I'd give it a try. But before I do, I'd like know if I can back up the Acronis Disc Imaging file to my external Hard Drive USB 2.0 (WD Essential 120gb), and then use it from that. Please let me know if I'm wrong here, but I'm assuming Acronis will save the backup file to the external HD, and when I need to use it ...I just turn on the external, reboot the computer...and press F11. Then it would show me the Acronis files on the external, and give me a choice of which Acronis Backup's I'd like to use. Then I choose the one I want, and start the process. Am I on the right track?
