Spanning Backup offers backup services for Google Apps users. The service costs $3.95 per month or $39.95 a year after a free 30 day trial. The company claims data loss and corruption is a serious problem for users of Google Apps. It’s cheaper than you’d miss forty bucks a year for a service that backs up your Google-hosted files in case of a cloud catastrophe, Spanning Backers says. It will backup calendars, contacts, and Google Docs files in the cloud if necessary.”]
