To be fair regarding cloud I sell both AWS (Amazon) and Oracle cloud as well as traditional infrastructure and the security applied to cloud is far beyond anything most home user's would have. Also, for corporate use, the information is usually replicated to a minimum of 2 other site's meaning three copies. In the event of a who data centre going down there would be the other copies located elsewhere. Virtually every bit of information you now give to your bank, gas company etc etc is stored in the cloud in one way or another.
