Microsoft revises website to show that all Windows 7 versions will have restore and backup.
Last month we gathered from Microsoft's Windows 7 comparison page that only the Professional and Ultimate editions had backup and restore functions.
It turns out that there was some confusion in the wording and Microsoft informed us that it has revised its website to convey that all version of Windows 7 will have backup and restore features. It is only the Professional and Ultimate editions that will be able to backup over a network.
The new comparison chart is revised to give the following feature to Professional and Ultimate: "In addition to full-system Backup and Restore found in all editions, you can back up to a home or business network."
Also, the following passage was added to the Backup and Restore page:
"You can back up to another drive or a DVD. And if you're using the Professional or Ultimate editions of Windows 7, you'll also have the option of backing up your files to a network."
So there you have it, folks – all versions of Windows 7 will have backup and restore, but the upper tier SKUs will be able to do it with a bit more convenience for advanced users.

Exchange backup on a client OS? Unlikely
It was always there to begin with, they've simply clarified their verbage on the matter.
No, That was system restore, not Microsoft Backup. Now, if only people would use it....
Vista Home Premium does come with backup software, it is just not "full backup and recovery" as in image recovery from hard drive crash like it is in win7 (I believe). It replaced Microsoft backup that was in XP. Nobody made a hugh deal out of it because it wasn't missing from one version, it didn't exist in any version.
I know someone that uses it because he downloads too much porn and sometimes get viruses from it
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."
