The Legacy of Agent-Based Backup
Historically, agent-based backup systems have been the norm. These systems operate by running software on the production machine, in tandem with the production application. The agent must communicate with its central data protection server for backups to be executed. The agent’s role is to read production data through the OS layer, process it, and transmit backup data to a media or backup server, where it is ultimately stored on a typically proprietary backup storage device.
