Help! Clone disk needs Windows restart



"I'm planning to back up my main disk to the external USB disk. If my main disk fails, I want to have a readily bootable disk, with a mirror image of my main drive, so I think cloning would be the best solution. As such, I opened Acronis True Image and started cloning, but I was extremely surprised to see that the cloning process involves rebooting the computer 3 times! Is this absolutely necessary? If I want to make this my regular backup method, having to reboot every time I want to clone the disk will be very unpractical. Thanks for your feedback."
