Techopedia explains Backup Client
The notion of a backup client is derived from the client/server architecture, where a client requests and is dependent on the server for any specific service. Similarly, the backup client communicates with a backup server to complete the backup process. Typically, a backup client can be a computer, server, networking hardware or a virtual machine. Usually, to initiate and execute a backup process, the backup client requires client-end backup software, which communicates with the backup server software or the backup server itself. The individual user/administrator can configure the backup client to select the type, location and schedule of data to be backed up.
