The recovery process from a local system failure is virtually immediate because data is available on a hot disk where it can be easily accessed and restored. With the ability to do many-to-one replication, multiple real-time copies can be made to different locations to provide the highest possible data protection.
Used alone, LKDR provides an efficient disk-to-disk data backup mechanism. When combined with LifeKeeper High Availability clustering, it becomes a powerful component in an overall Exchange protection solution.
