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
storage device.
