I'm quite a computer novice, and would appreciate any help in understanding how Acronis's True Image software works. I have an 80 gb internal hard drive. I plan on buying an external 80gb USB 2.0 hard drive to use for backing up my internal drive. I'm trying to figure out what software to use for the backing up. I have been researching True Image, but have some questions... Is True Image really easy to use? I want True Image to make an exact copy of my hard drive, and then each night, I want it to automatically figure out what changes have been made on my PC, and then copy those changes onto the copy located on my external hard drive. Can it do this, and can it be set to automatically happen at a certain time each night? If someday I turn on my PC and it tells me that the internal hard drive has failed, how hard is it to boot up my pc from the "copy" that True Image has made on my external drive? Any information you can offer is greatly appreciated. Thank you so much.
