Explanation

Backup Architecture A backup system commonly uses the client-server architecture with a backup server and multiple backup clients. Figure on the slide illustrates the backup architecture. The backup server manages the backup operations and maintains the backup catalog, which contains information about the backup configuration and backup metadata. Backup configuration contains information about when to run backups, which client data to be backed up, and so on, and the backup metadata contains information about the backed up data. The role of a backup client is to gather the data that is to be backed up and send it to the storage node. It also sends the tracking information to the backup server. The storage node is responsible for writing the data, to the backup device. In a backup environment, a storage node is a host that controls backup devices. The storage node also sends tracking information to the backup server. In many cases, the storage node is integrated with the backup server, and both are hosted on the same physical platform. A backup device is attached directly or through a network to the storage node's host platform. Some backup architecture refers the storage node as the media server because it manages the
