What method creates a data backup on remote storage through the Internet?

Online data backup is the correct method for creating a data backup on remote storage through the Internet. This process typically involves transferring data over the internet to an off-site server or cloud storage service, allowing users to access their backed-up information from anywhere with an internet connection. Online backups provide the advantage of automatically scheduled backups, ease of access, and the ability to handle large quantities of data without the need for physical media.

In contrast, offline backup refers to methods where data is stored on local storage devices that are not connected to the internet, making them less accessible for remote recovery. Local backup involves storing data on physical devices, such as external hard drives, that are typically used in the same physical location as the original data. Physical backup is another term often associated with local backup methods and does not imply any remote or online capabilities. Thus, the option focused on internet connectivity directly reflects the modern solutions for data protection and recovery, which is why online data backup is the correct response.
