I have written often about the need to keep secure and encrypted backups of your important files off-site. Actually, I believe every computer owner should do that but it is doubly important for genealogists who have often spent hundreds of hours researching and documenting their family trees. A loss of all that data caused by a hard drive crash, a hurricane, a tornado, any other natural disaster, or simple human error, can be devastating.
Most corporations are moving their corporate data to cloud-based backup systems, whether they create their own cloud computing systems or use one of the commercially-available cloud solutions (Amazon Web Services, RackSpace, Microsoft Azure, Google Cloud, IBM Cloud, DigitalOcean, and many others).
Now Microsoft is moving many of its customers who use Microsoft Office (Word, Excel, PowerPoint, and other applications) to cloud computing in an effort to improve the customers’ security and redundancy.
