A remote, online, or managed backup service is a service that provides users with an online system for backing up and storing computer files. Managed backup providers are companies that provide this type of service.
Online backup systems are typically built around a client software program that runs on a schedule, typically once a day. This program collects, compresses, encrypts, and transfers the data to the remote backup service provider's servers. Other types of product are also available in the market, such as remote continuous data protection (CDP).
Providers of this type of service frequently target specific market segments. High-end LAN-based backup systems may offer services such as near-realtime transaction-level replication or open file backups. Consumer online backup companies frequently have beta software offerings and/or free-trial backup services.
