Long Zheng: One of the most compelling features of the Windows Home Server is the automated image backup to the network share. However if you find a home server a little too much (or expensive) like I do, then youd be glad to know Windows 7 will make the job of making Windows Complete PC Backups at least half as easy by allowing you to backup straight to a network share.
Whereas in Vista you could only do a complete backup to hard disk or DVDs (with files you could backup to network share), taking it one step further to the network share makes it much easier to do backups especially since you cant backup to the same drive as the operating system. And I dont think anyone will juggle 71 DVDs to backup their 500GB hard drive. I guess nows a good a time as any to buy a NAS device.
