Important Terms and ConceptsINTRODUCTIONNOTE: The following discussion regarding various aspects ofMicrosoft Exchange Server 2007 replication draws heavily oncontent authored by Microsoft Corporation.However, a complete discussion of Exchange Server 2007replication is beyond the scope of this publication. Refer toyour Microsoft Exchange Server 2007 documentation foradditional information.Local Continuous Replication (LCR)Local continuous replication (LCR) is a single-server solution that uses built-inasynchronous log shipping and log replay technology to create and maintain acopy of a storage group on a second set of disks that are connected to thesame server as the production storage group. The production storage group isreferred to as the active copy, and the copy of the storage group maintainedon the separate set of disks is referred to as the passive copy. The followingillustration shows a basic LCR deployment.LCR deployments do not require any special Avamar Exchange Client set up orconfiguration. Install the Avamar Exchange Client software on the activestorage group using the normal (non-cluster) installation procedure. Refer toInstalling/Uninstalling Avamar Exchange Client (page 18) for additionalinformation.Cluster Continuous Replication (CCR) and Standby Continuous Replication (SCR)Cluster continuous replication (CCR) is a high availability feature of MicrosoftExchange Server 2007 that combines the asynchronous log shipping andreplay technology built into Exchange Server 2007 with the failover andmanagement features provided by the Windows Cluster service.AVAMAR 5.0 • AVAMAR EXCHANGE CLIENT USER GUIDE 10
System RequirementsINTRODUCTIONCCR is designed to provide high availability for Exchange Server 2007 Mailboxservers by providing a solution that:• Has no single point of failure• Has no special hardware requirements• Has minimal shared storage requirements• Can be deployed in one or two datacenter configurationsCCR uses the database failure recovery functionality in Exchange Server 2007to enable the continuous and asynchronous updating of a second copy of adatabase with the changes that have been made to the active copy of thedatabase. During installation of the passive node in a CCR environment, eachstorage group and its database is copied from the active node to the passivenode. This operation is called seeding, and it provides a baseline of thedatabase for replication. After the initial seeding is performed, log copying andreplay are performed continuously.In a CCR environment, the replication capabilities are integrated with theCluster service to deliver a high availability solution. In addition to providingdata and service availability, CCR also provides for scheduled outages. Whenupdates need to be installed or when maintenance needs to be performed, anadministrator can move a clustered mailbox server (called an Exchange VirtualServer in previous versions of Exchange Server) manually to a passive node.After the move operation is complete, the administrator can then perform theneeded maintenance.CCR can be combined with standby continuous replication (SCR) to replicatestorage groups locally in a primary data center (using CCR for high availability)and remotely in a secondary or backup datacenter (using SCR for siteresilience). The secondary datacenter could contain a passive node in afailover cluster that hosts the SCR targets. This type of cluster is called astandby cluster because it does not contain any clustered mailbox servers, butit can be quickly provisioned with a replacement clustered mailbox server in arecovery scenario. If the primary datacenter fails or is otherwise lost, the SCRtargets hosted in this standby cluster can be quickly activated on the standbycluster.System RequirementsThis topic lists the supported configurations and hardware requirements that mustbe satisfied in order to successfully install and deploy the Avamar Exchange Clientbackup and recovery solution at your site. The supported configurationsinstallation package column also lists the correct Avamar Exchange Client softwareinstallation package required for that specific Exchange version, host platform andoperating system.AVAMAR 5.0 • AVAMAR EXCHANGE CLIENT USER GUIDE 11
