This was a mistake by Microsoft, de-emphasizing the full disk backup options. There were serious issues with it, it was pretty brittle in terms of backing up and restoring* but those problems should have been fixed rather than obscured. To find the Windows 7-style backup options, hit start, type "Backup" and select "File History". Then in the bottom left corner, click "System Image Backup". The GUI is there, it's just been needlessly hidden. :(
