Introduction to Storage Mirroring
Storage Mirroring is a real-time data replication and failover software product. Storage Mirroring augments your existing data
protection strategy by reducing downtime and data loss, and it provides these services with minimal impact on existing
network and communication resources.
Storage Mirroring allows you to specify mission-critical data that must be protected and replicates, in real-time, that data from
a production machine, known as the source, to a backup machine, known as the target. The target machine, on a local
network or at a remote site, stores the copy of the critical data from the source. Storage Mirroring monitors any changes to
the critical data and sends the changes to the target machine. By replicating only the file changes rather than copying an entire
file, Storage Mirroring allows you to more efficiently use resources.
Storage Mirroring lets you implement various data protection solutions including:
‹ Local high availability services
‹ Offsite disaster recovery services
‹ Enhanced centralized backup using third-party backup systems
