Recommended Configuration - ARCserve Primary and Members Servers Installed in a Cluster-aware Environment

If your current configuration consists of multiple CA ARCserve Backup servers in a cluster-aware environment, the best practice is to upgrade to multiple CA ARCserve Backup Primary Servers or multiple CA ARCserve Backup Stand-alone Servers.

This architecture lets you centrally manage your CA ARCserve Backup environment and maintain the high availability capabilities of a cluster-aware environment.

To deploy this configuration in your environment, you can use Microsoft SQL Server 2008 Express Edition or Microsoft SQL Server to host the CA ARCserve Backup database.

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 multiple CA ARCserve Backup servers in a cluster-aware environment in this release. The CA ARCserve Backup database is hosted using Microsoft SQL Server 2008 Express Edition and the CA ARCserve Backup database instance resides on the CA ARCserve Backup server.
