Continuous Replication Deep Dive in Exchange Server 2007
Continuous replication (also known as log shipping and replay) is new technology in Microsoft Exchange Server 2007 that creates and maintains database copies to provide full high availability and disaster recovery solutions for mailbox databases. With the release of Exchange Server 2007 Service Pack 1 (SP1), there are now three forms of continuous replication.
- Local Continuous Replication (LCR) LCR is a single-server solution that uses continuous replication to create and maintain a copy of a storage group on a second set of disks connected to the same server as the active storage group copy. For more information, see Local Continuous Replication.
- Cluster Continuous Replication (CCR) CCR is a high availability feature that provides failover capabilities for e-mail service and mailbox data, using continuous replication to provide one copy of data redundancy with clustering technology for the server redundancy. For more information, see Cluster Continuous Replication.
- Standby Continuous Replication (SCR) SCR is a disaster recovery feature that employs continuous replication to create and maintain multiple copies of a storage group. It is provided as a feature to facilitate site resiliency. For more information, see Standby Continuous Replication.
