Local Continuous Replication


Local Continuous Replication (LCR) which formerly was known as the Local Continuous Backup feature is, when speaking high availability and total cost of ownership (TCO), an extremely interesting new feature. Local continuous replication (LCR) is a single-server solution that uses built-in asynchronous log shipping and log replay technology to create and maintain a copy of a storage group on a second set of disks that are connected to the same server as the production storage group. The production storage group is referred to as the active copy, and the copy of the storage group maintained on the separate set of disks is referred to as the passive copy. We all know that the costs associated with backups, restores etc. has grown considerably over the last couple of years, especially with messaging servers, but since you, when using the LCR feature, always have an exact copy (replica) of a production storage group, it reduces the number of regular backups you need to perform.
