Recommended Configuration - CA ARCserve Backup Domain with a Primary Server and Member Servers

If your current configuration consists of multiple CA ARCserve Backup servers in a domain, the best practice is to upgrade to a centralized management environment that consists of a primary server and one or more member servers.

To upgrade to a centralized management environment, you must upgrade one of your existing CA ARCserve Backup servers to a CA ARCserve Backup Primary Server and then upgrade all other servers in the domain to CA ARCserve Backup Member Servers.

Note: The domain primary from your previous installation must assume the role of the CA ARCserve Backup Primary Server.

To install member servers, the installation wizard must be able to detect the CA ARCserve Backup domain name and primary server name in your network. You should therefore install CA ARCserve Backup on at least one primary server before you install member servers.

Note: Microsoft SQL Server 2008 Express Edition does not support remote communication. When you install CA ARCserve Backup using Microsoft SQL Server 2008 Express Edition, the installation wizard installs the database application and the ARCserve database instance on the primary server. To host the ARCserve database instance on a remote system, you must use Microsoft SQL Server.

The following diagram illustrates the architecture of a centralized management environment:

Note: To enable CA ARCserve Backup to communicate with a remote database, you must use Microsoft SQL Server to host the ARCserve database.
