Architecture and components
Cohesity Data Cloud for NetBackup uses a distributed architecture that integrates NetBackup with Cohesity Data Cloud to support scalable backup, duplication, and replication operations. The solution separates control and data paths while enabling optimized data movement between NetBackup and Cohesity storage.
At a high level, NetBackup continues to manage backup policies, scheduling, catalogs, and job control, while Cohesity Data Cloud provides the underlying storage, data services, and distributed processing capabilities through its SpanFS architecture.
The solution consists of the following main components:
NetBackup primary server
Manages backup policies, schedules, catalogs, and overall job coordination. It acts as the control point for configuring and monitoring NetBackup operations.
NetBackup media server
Responsible for data movement and metadata processing. The media server participates in optimized data paths and coordinates data transfer between NetBackup and Cohesity storage.
NetBackup clients
Host the workloads being protected. Clients can participate directly in data transfer operations when Client Direct is enabled, reducing load on media servers.
Cohesity Data Cloud cluster
Provides distributed storage, data services, and replication capabilities using the SpanFS file system. The cluster enables scalable storage and optimized data services for NetBackup workloads.
This architecture supports multiple deployment models, including Client Direct, media server - based, and mixed deployments. These models allow customers to scale performance and concurrency while maintaining familiar NetBackup workflows.
