I guess this is a joke... 2 months for such an update...
This problem has been reported by several users. If your backup includes a system image, then Windows will eventually take 3-4 minutes to boot. Otherwise, for a regular backup WITHOUT a system image, it takes 30 seconds.
I have already troubleshooted the problem with the system performance profiler and the process eating all the startup time is related to the partition integrity check. So please check the problem on your end and come back with a fix ASAP!
