Risks of the Cloud
One of the risks of putting your data on the "Cloud" is the service provider may just decide to shut it down at some random time of their choosing, as demonstrated by this news item. My approach, rather, is to keep the primary copy on my own system, and use the cloud for backup and for accessibility (to others, and to myself when mobile). If one provider shuts down, I still have the original data, and can post it to another provider if needed.
