Techopedia explains Backup Server
A backup server is generally implemented in an enterprise IT environment where computing systems across an organization are connected by a network to one or more backup servers.
A backup server consists of standard hardware server with substantial storage capacity, mostly with redundant storage drives and a purpose built backup server application. The backup schedule for each computer may be installed with a client utility application or configured within the host operating system (OS). At the scheduled time, the host connects with the backup server to initiate the data backup process. The backup may be retrieved or recovered in the event of data loss, data corruption or disaster recovery.
In the context of a hosting or cloud service provider, a backup server is remotely connected through the Internet on a Web interface or through vendor application programming interfaces (API).
