Wow this is familiar lol.....<p>My hybrid cloud storage team here at Microsoft in Silicon Valley (which was a startup called StorSimple that Microsoft acquired) already built this feature for our hybrid cloud storage virtual appliance that released a few months ago and its already in production and being used by customers.....<p>We called it Just in Time Item Level Restore but it&#x27;s the exact same thing........and looks exactly the same in behavior as well.....and we have various optimization to make it efficient and deal with latency and stuff.....<p>(Btw we have nothing to do with one drive or one drive for business. That&#x27;a completely separate team. We only build enterprise storage devices)<p>Ugh this is why you want to be in the consumer space , not the enterprise space.<p>If a consumer product and enterprise product make the exact same thing&#x2F;product, most people remember&#x2F;see the consumer product.<p>The race conditions and clever data structures  to represent the file blobs and file system structure in the cloud to do this efficiently is actually very cool......I&#x27;m not sure how they (Dropbox) implemented it but I wonder how similar it would be to how we did it.<p>Oh well this is my last week here in Microsoft and I&#x27;m moving to Apple in a different space so I guess I don&#x27;t really care about storage anymore lol.<p>At least at Apple the cloud services and applications will be the backend for consumer used front end applications.<p>People will think Dropbox was the first one to do this because it&#x27;s in consumer space so it&#x27;s more well known......<p>Well actually I can link all the public announcements and stuff that was dated long before this video on the feature.<p>We should have made a public video like this. We have videos but they were all for internal demos....<p>Click the Preview link (skip to item level recovery section but the PM explanation doesn&#x27;t do it justice so you won&#x27;t see it as the same from a technical feature point of view but it&#x27;s exactly the same and behaved the same zero storage on disk but the file system thinks it&#x27;s there)<p>To accomplish all our feature we actually have low level stuff as well but I can&#x27;t go into the details since I&#x27;m not allowed to so I&#x27;ll leave it at that.<p>But Dropbox is a great company and I&#x27;m glad this feature is now available to Consumers not just enterprise.<p><a href="https:&#x2F;&#x2F;azure.microsoft.com&#x2F;en-us&#x2F;blog&#x2F;announcing-the-storsimple-virtual-array-preview&#x2F;" rel="nofollow">https:&#x2F;&#x2F;azure.microsoft.com&#x2F;en-us&#x2F;blog&#x2F;announcing-the-storsi...</a><p><a href="https:&#x2F;&#x2F;azure.microsoft.com&#x2F;en-us&#x2F;blog&#x2F;announcing-general-availability-of-the-storsimple-virtual-array&#x2F;" rel="nofollow">https:&#x2F;&#x2F;azure.microsoft.com&#x2F;en-us&#x2F;blog&#x2F;announcing-general-av...</a>
