Core components

Yosemite Backup is built upon a modular architecture comprised of three primary components: a Master Server, one or more Media Servers, and one or more Client Servers. When combined, all 3 components make up a Yosemite Backup Domain. For small environments (e.g. one server), all three components are installed together to provide single-server protection. For larger environments the components can be separated and installed on their own dedicated servers.

Yosemite Backup's Modular Architecture includes:

Component 1: Yosemite Backup Master Server:
The Master Server is the primary component that makes up the Yosemite Backup Domain and is where all administrative functions such as backup job creation and management, scheduling, monitoring, reporting and recoveries are performed. There can be only one Master Server in a Backup Domain because the Master Server is where the Yosemite Backup catalog is stored and updated. The Master Server can run natively on Microsoft Windows, Netware or Linux operating systems.
Component 2: Yosemite Backup Media Server:
The Media Server is the second primary component of the Backup Domain and acts as a resource to the Master Server. The Media Server receives all the data from the Client Servers, optionally encrypts the data (NEW!), and either stores backup data directly on disk or writes it out to directly-attached supported archiving devices such as tape drives/libraries, CD/DVD devices and more. Yosemite Backup Standard supports up to 5 Media Servers and Yosemite Backup Advanced supports an unlimited number of Media Servers in a Backup Domain. The Media Server can run natively on Microsoft Windows, Netware, or Linux operating systems.
Component 3: Yosemite Backup Client Server:
The Client Server is the third primary component of the Backup Domain. The Client Server is the server that hosts applications and databases used to run the business. When the Yosemite Backup Client Server is installed on these servers, the Client Server component "pushes" data to the Media Server for writing out to archiving devices. The Client Server can run natively on Microsoft Windows, Netware, or Linux operating systems.

Master Server

The Master Server is the primary component that makes up the Yosemite Backup Domain and is where all administrative functions such as backup job creation, scheduling, monitoring, reporting and recoveries are performed. The Master Server is also where the backup catalog is located and there can be only one Master Server per Backup Domain. The Master Server can run natively on Microsoft Windows, Netware or Linux operating systems.

Media Server

The Media Server is the second primary component of the Backup Domain and acts as a resource to the Master Server. The Media Server receives all the data from the Client Servers, optionally encrypts (NEW!) and either stores backup data directly on disk or writes it out to directly-attached supported archiving devices such as tape drives/libraries, optical, and more. Yosemite Backup Standard supports up to 5 Media Servers and Yosemite Backup Advanced supports an unlimited number of Media Servers in a Backup Domain. The Media Server can run natively on Microsoft Windows, Netware, or Linux operating systems.

Client Server

The Client Server is the third primary component of the Backup Domain. The Client Server is the server that usually serves up applications, databases, or file/print functions. When the Yosemite Backup Client Server is installed on these servers, it "pushes" data to the Media Server for writing out to archiving devices. The Client Server can run natively on Microsoft Windows, Netware, or Linux operating systems.
