Certified Cloud Security Professional (CCSP) Practice Exam

Online backup primarily functions by utilizing the Internet and cloud computing technologies to facilitate off-site data storage. This method offers significant advantages, such as ensuring that critical data is securely stored in a remote location, which protects it from local hardware failures, natural disasters, or other incidents that may compromise data integrity on the primary site. Minimal hardware requirements are appealing for organizations since they can leverage cloud resources without the need for extensive physical infrastructure.

The other options do not encapsulate the full scope of online backup. Storing data solely within an enterprise's private cloud limits the benefits associated with off-site backups and may not provide the same level of disaster recovery as utilizing an external cloud provider. Renting hardware and software over the Internet refers more to infrastructure as a service (IaaS) rather than backup solutions. Lastly, a focus on mobile devices neglects the critical need for comprehensive data protection across various environments, including servers and workstations, making it a limited representation of online backup’s capabilities.
