Christian is installing new computers at his accounting company. He's going to be transferring the data from one computer to another and wants to know if Google Drive will work. Leo says absolutely not. There are serious privacy issues handling a client's financial information and personal details. Carbonite is a better option that is encrypted. He'll want to be sure that the data is not only encrypted at the destination but also in transit and that the keys are well controlled, ideally only by him. Microsoft has SharePoint, which uses Azure servers to protect. Leo would advise contacting Microsoft Business Services for an estimate.
