Microsoft team creates data-storage system that lasts for millennia

In the digital age, the need for data storage is ballooning. But current magnetic tapes and hard drives are ill-suited for long-term data storage because they degrade in about ten years.The Microsoft team used a high-energy laser to imprint deformations into a 3D chunk of borosilicate glass, the kind used in ovenware. Each deformation encodes data that can be read out using a microscope.Researchers use mini plasma explosions to encode the equivalent of two million books into a coaster-sized device. The method could preserve research data for millennia with minimal storage costs. What is your take on storing data for so long on the cloud ?
