Depending upon the type of event, continuity of a given application is achieved by falling over its services and user/client access locally within the same datacentre or to a remote, physically disparate datacentre. With business continuity, the failover of a service is measured in seconds or less. Backup technologies, including those that rely on disk as a backup target, can’t provide this level of continuity of services. Backups, in order to be used a restoration process and are typically used for disaster recovery purposes.
