The main data protection software component is the Master; which is installed on a dedicated server that acts as a central hub, communicating with users through REST interface and web-based UI. The Master monitors and controls the activity of a set of Clients; software components installed on servers in the protected environment. Normally, the Master does not actively take part in data protection data flows; Clients do this according to rules distributed from the Master.
-
A Master that controls the UI and the actions of all other nodes on the environment.
Master nodes can coexist on the same network, allowing multiple data protection environments to coexist.
Passive standby master nodes can be installed on a Windows failover cluster so that the standby can be brought online in the event that the active master fails.Note: It is recommended that the Master server not be assigned any other roles. -
Multiple Clients that participate directly in data protection data flows, acting as sources of data to protect (for example, database servers) and destinations capable of receiving backup data (for example, repositories).
Clients implement various different roles within a data flow and must be configured to perform these roles. This consists of ensuring the appropriate prerequisites are installed, and configuration using the UI.
Client nodes can be installed on application clusters such as Oracle RAC.
Each Client can only be authorized and controlled by one master.
The figure below shows an installation scenario where two completely independent data protection environments coexist on one network.
