What is the best backup utility, and is there a program similar to OS X's Time Machine for Windows? Time Machine is a backup program that automatically copies every file, unless I exclude them, to an external hard drive. I can remove the hard drive, and when I plug it back in it automatically copies over any changes I made. Then, if my computer fails I can restore everything from the backup and it will be exactly as I have left it. I love Time Machine, but I also love Windows. As I'll be in college, using OneNote and doing homework, if I dont have my data on my laptop always backed up, if something goes wrong I could be in a lot of trouble. Also, if no such program exists, what is the best backup utility for Windows?
