  • O Exchange 2007 possui os seguintes mecanismos de alta disponibilidade:

    • Local continuous replication
    • Cluster continuous replication
    • Single copy clusters
    • Standby Continuous Replication

    Cluster continuous replication (CCR) is a high availability feature of Microsoft Exchange Server 2007 that combines the asynchronous log shipping and replay technology built into Exchange 2007 with the failover and management features provided by the Cluster service.

    CCR is designed to provide high availability for Exchange 2007 Mailbox servers by providing a solution that:

    * Has no single point of failure.
    * Has no special hardware requirements.
    * Has no shared storage requirements.
    * Can be deployed in one or two datacenter configurations.
    * Can reduce full backup frequency, reduce total backed up data volume, and shorten the service level agreement (SLA) for recovery time from first failure.
