A remote, online, or managed backup service is a service that provides users with a system for the backup and storage of computer files. Online backup providers are companies that provide this type of service to end users (or clients).
Online backup systems are typically built around a client software program that runs on a schedule, typically once a day, and usually at night while computers aren't in use. This program typically collects, compresses, encrypts, and transfers the data to the remote backup service provider's servers or off-site hardware.
