This is an excellent example of bad journalism.
The original story was simply false, and it took some 3 weeks for its author to post a new story containing the correct information, albeit without acknowledging his own original error.
Even more incredibly, the author has not yet posted a correction within the original story. It is still up there, headlined "Windows 7 Home Premium Won't Have Backup," continuing to this day to misinform all who may read it.
Apparently, the author took little care before posting the original story. For example, it is apparent that he did not carefully read the available Microsoft site information, did not contact Microsoft ahead of time, did not carefully search the internet for the correct information, and did not actually test the pre-release version of the product. Evidently, he simply misread the information posted on the Microsoft site, and then leaped to his incorrect conclusion. Further, his latest story rather pathetically tries to shift blame to Microsoft, after it changed its site wording, in an attempt perhaps to idiot-proof its site information.
Here is the link to the original false and still uncorrected story. If you will read all of the comments, including my own, to see the various attempts made by many readers, including myself, to correct the story. The comments also show the degree to which this story misinformed its readers (and indeed will no doubt continue to do so, for it is still present on the site, with no annotation that its basic claim is simply false).

Here are some links to a responsible site, at which you could have read the correct information, several weeks before the Tom's Hardware author provided you with the incorrect "news."
