Abstract

Abstract A remote data backup service is provided for clients, typically small or medium-sized enterprises. A backup server computer is connected to the client computers over a public ISDN network, and automatically initiates regular backups according to an agreed schedule. Clients are charged for the service according to usage. In the event of a failure in the backup server, an alert message is sent to a pager device to call a service technician. The backup server comprises a pair of computers connected together in a high-availability configuration. The backed-up data is stored in an automated tape library, and is periodically cloned to provide copies for off-site storage.
