Andrea Works as an Administrative Assistant for a Small Business

Andrea works as an Administrative Assistant for a small business that uses an SaaS service for accounting, sales orders and customer service information about the business's customers. This product is similar to Salesforce.com and its competitors. Andrea makes sure she saves accurate records about current projects and performs regular backups of the business data stored on the cloud-based service. Which of the following is the primary reason for this practice?

A) If there is an interruption in Internet access, the service and records would not be accessible.
B) There is a limit on the number of users who are allowed to access the cloud-based service at any one time.
C) Data stored online through the cloud-based service is more at risk to security breaches than if it were stored locally.
D) Andrea is overly cautious because it is well known that cloud-based services are highly secure, highly reliable and always available.
