Man... I spent forever trying to find a product comparison like that... thanks for the link.<br />
<br />
What's the difference between Load Balancing Clusters and Server clusters (assuming there is something less obvious than the name).

<div class="content wysiwyg-content">
It's my understanding that the standard version of server 2003 can do a 2 node cluster, but you need to go up to Enterprise for more than a 2 node. &nbsp;Is that correct or am I mistaken?<br />
<br />
Also, do I need to go to the Enterprise version of Exchange 2003 in order to do any clustering at all?<br />
<br />
Thanks!

Clustering in different versions of Server 2003

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Storage Software

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
