Could our reliance on the cloud cause problems as we all centrally store information on the cloud.
Cloud computing and the likes of virtual applications such as google apps and office 365 store all your data on centralized servers. This means documents that are important to you are often not in your complete control. However what you can do is to export documents and push these into other services so you have suitable backups and no over reliance on one service. Services such as safesync, windows live and apple offer free services that enable you to store backup documents.
