Before you can understand the details of Global Dashboard, you must be familiar with some of the terms and definitions used by this utility.
Global Dashboard uses the following terms and definitions:
The Central Primary Server (and its associated Arcserve Backup database) is the central hub interface for storing synchronized dashboard-related information received from Branch Primary Servers. Within your Arcserve Backup environment, there can only be one primary server configured as the Central Primary Server, and a Branch Primary Server can only report to one Central Primary Server. All associated Branch Primary Servers need to be registered with this Central Primary Server to enable network communication. Communication is always one way, from a branch site to the central site. The terms Central Primary Server and Central Site are used interchangeably in this document.
Any primary server (or stand-alone server) within your Arcserve Backup environment can be configured to be a Branch Primary Server. A Branch Primary Server synchronizes dashboard-related information to the designated Central Primary Server. All data is transmitted from the Branch Primary Server to the associated Central Primary Server. Within your Arcserve Backup environment, there can be multiple Branch Primary Servers, but only one Central Primary Server. In addition, a Branch Primary Server can only report to one Central Primary Server. After a primary server is configured as a Branch Primary Server and registered with the associated Central Primary Server, the corresponding dashboard data can be automatically synchronized with the Central Primary Server. The terms Branch Primary Server and Branch Site are used interchangeably in this document.
The Global Dashboard Console is the user interface for displaying the synchronized dashboard information (reports). The Global Dashboard Console is basically an expanded version of the Arcserve Backup Dashboard GUI, with some additional capabilities and options. All dashboard reports that can be displayed from the Arcserve Backup Dashboard can also be displayed from the Global Dashboard Console. However, the Global Dashboard Console lets you view these dashboard reports for any one or group of registered branch sites.
The Central Manager provides a snapshot overview of your entire Global Dashboard environment. This user interface lets you quickly and easily monitor the status of any or all registered branch sites from a single location. The Central Manager also displays any log messages associated with the branch sites. The Central Manager is accessible from the Global Dashboard Console (when the Global View mode is selected) by clicking the icon button on the Global Dashboard toolbar.

Data synchronization is the process of transmitting dashboard-related information from a branch site database to the central site database so that the central database contains (and reports) the same information as each of the registered branch databases. For Global Dashboard, the initial data synchronization will always be a full data synchronization. All subsequent data synchronizations will be incremental. Incremental synchronization is synchronizing the data that was modified, deleted, or added since the last synchronization was performed. The synchronized data is compressed to minimize size prior to transmittal.
During a full synchronization process, the Arcserve Backup database engine will be shut down for a few minutes. During an incremental data synchronization, no Arcserve Backup services will be shut down.
The full data synchronization process is basically a three-step process:
The incremental data synchronization process is basically a three-step process:
