If you aren't on the cloud, you're at risk of losing all the information you had saved locally. With a cloud-based server, however, all the information you've uploaded to the cloud remains safe and easily accessible from any computer with an internet connection, even if the computer you regularly use isn't working.

Well this is not always true, you may have disaster sites, clustered hosts,  Data Storage replications and more. but all these have a cost, maybe for a small company cloud is cheaper.
