reliable backup for protecting virtual machines (VM), as well as physical and cloud
environments.

Cluster Continuous Replication (CCR)
A non-shared storage failover cluster solution, that uses built-in asynchronous log shipping
technology to create and maintain a copy of each storage group on a second server in a

both high availability and site resilience. It is one of two types of clustered mailbox server
(CMS) deployments available in Exchange 2007.
Cluster Node
An individual machine that is part of a Windows Failover cluster.
Compression
