Online backup services let you back up important files and data to hosted storage. Online backup is a relatively recent development. Historically, data backup used local storage media such as tape drives or burning to CD. The development of the Internet enabled online backup. During the dot-com era, free online backup companies like Visto and XDrive proliferated, but failed to generate a sustainable online backup business. Today, as bandwidth and disk costs continue to decrease, other players like Google may get into the online backup business.
