CommServe and MediaAgent

From a single, centralized management console, you can automate global protection and retention policies while secure, self-service access enhances availability of information and reduces help desk requests. Data Protection Suite software extends beyond just better backup and recovery to improving your workforce productivity and business efficiency.

There are two key components in a CommCell management group -- the CommServe server, and one or more MediaAgents.

CommServe

The CommServe server is the central management system within a CommCell group, coordinating and managing all activity. It maintains a Microsoft SQL metadata database which contains all critical configuration information.

Key points regarding the CommServe server:

  • Only one active CommServe server can exist within a CommCell group. Standby CommServe servers can be preconfigured in the event the primary server goes down.
  • For CommServe server high availability the following options are available:
    • The CommServe server can be clustered – This is recommended for larger environments where high availability is critical.
    • The CommServe server can be virtualized – This is suitable for smaller environments.
  • CommServe metadata must be properly protected. By default, a CommServe DR backup job is conducted daily. This operation can be customized and configured to run multiple times a day if required.
  • All activity is conducted through the CommServe server, therefore it is important that communication between the CommServe server and all CommCell group resources always be available.

MediaAgent

The MediaAgent is the data transmission manager in the CommCell group. It provides high performance data movement and manages the data storage libraries. MediaAgent tasks are coordinated by the CommServe server. For scalability, there can be more than one MediaAgent in a CommCell. The MediaAgent software can be installed in physical, virtual, and clustered environments. For more information about MediaAgents, see MediaAgent - Overview.
