Symantec's Norton Utilities maximizes your computer's performance.It finds and repairs disk problems at the click of a button, and can alert you to potential problems before they cause trouble.Redundant network paths, DNS and Active Directory servers, and Exchange front-end (client access) and clustered servers turn failures into inconveniences instead of disasters.Some failures can be automatically handled with little apparent effect on the system.What's most important is to have a strategy for protecting and recovering each of the components noted previously.Regardless of the details of your strategy, you should take into account the following: What disasters won't your strategy handle?However, additional available disk space may be needed during an upgrade to allow for the creation of temporary files.
This distributed design makes rebuilding a damaged Exchange server nearly automatic.
I'll also discuss recovery of server installations and configuration information, and re-assignment of special Exchange server roles after a disaster (see the sidebar "Special Server Roles").
Redundancy is the first principle of disaster recovery.
In all but the smallest organizations, Exchange Server 2003 runs as a distributed system.
This architecture provides Exchange with a great degree of resiliency.
