Hi, In February, my ibook G4 was experiencing a Kernel Panic, so I thought on backing up the information. I backed everything up in an external hard drive and erased some 60 GB of information from the computer. I did this, knowing that Time Machine had saved a copy of my entire information, (some 120 GB). Now, in April, I needed to restore all the information back to my ibook in order to work on that information. Well, no problem, I started the ibook and then plugged in the external hard drive. The only thing I noticed is that the little icon from "Time Machine" was working. I clicked on it and then I had two choices: *Stop Backing up *Enter Time Machine I have two questions with this regard: 1. What happens if I stop backing up ?? 2. I clicked on the choice "Enter Time Machine" and it gives me three choices: * Cancel * Today (Now) * Restore How can I restore to February 2011 ?? 3. Does Time Machine backs up different "Time Machines", I mean, according to different dates or it only saves THE LATEST back up ?? Thank you, kind regards, igmolinav : ) !!!
