How the Central Administration Server Option (CASO) Works in Backup Exec 10.x and above.


Solution



In a CASO-enabled Backup Exec (tm) environment, a group of standard stand-alone Backup Exec media servers are managed and monitored from a Backup Exec media server where
CASO has been installed. This media server, known as the central administration server, becomes the focal point of a CASO-based Backup Exec data protection environment, and
it is where all Backup Exec-related administration tasks occur.  The remaining media servers become managed media servers, which are managed using the central administration server.

After configuring a CASO environment, create policies and selection lists at the central administration server. Jobs created from these policies and selection lists can use
the CASO job delegation feature, which automatically delegates Backup Exec jobs among the various storage devices connected to the managed media servers in the CASO environment

CASO Configuration Scenarios

The following diagrams show implementations of CASO in a Backup Exec environment, beginning with a diagram of a typical Backup Exec installation.  This diagram shows a typical local area network environment where multiple Backup Exec media servers are configured independently of each other. As such, each media server processes jobs independently. Administration tasks for each media server are handled at the individual media servers.

The next diagram shows a local area network environment where one Backup Exec media server is designated as the central administration server, while other media servers become managed media servers, communicating directly with, and being managed and monitored from, the central administration server. Backup Exec jobs can also be delegated by the central administration server to each of the managed media servers for processing.
