Hitachi ShadowImage Replication software

Host-independent, Nondisruptive Volume Replication

  • Provides high-speed, nondisruptive, full-volume, RAID-protected local mirroring and point-in-time capabilities for Hitachi storage platforms.
  • Ideal for either open systems or mainframe environments.
  • Enables nearly instant point-in-time recovery from data corruption or data loss compared to non-disk based solutions, such as tape- or vault-based recovery.

Full Data Replication Solution

Hitachi ShadowImage Replication software is a nondisruptive, host-independent, data-replication solution for creating copies of any IT administrator-accessible data within a single Hitachi storage system. ShadowImage Replication also maintains the availability of host applications by enabling backup operations to run concurrently while business or production applications are online.

Features and Benefits


  • Provides high-speed, nondisruptive, full-volume local mirroring technology with quick restore capability.
  • Creates RAID-protected point-in-time copies and allows full recovery without affecting live production environments.
  • Easily splits mirrored data volumes from the primary data source without impact to host applications.
  • Consistency group function enables replication in unison across multiple data volumes.
  • Allows simultaneous splitting of multiple replicated volume pairs.


  • Shortens application or database restart and recovery times from data loss with point-in-time copies.
  • Allows for creation and cascade of data copies across a single data volume or multiple data volumes.
  • Dramatically reduces data recovery time with a quick-restore feature, which allows an immediate restore to a disk-based recovery point.
  • Replicates large data volumes without impacting service levels, timing out, or affecting performance levels.
  • Facilitates data sharing and migration, when used with Hitachi TrueCopy or Hitachi Universal Replicator software, for decision making, testing and development, and data analysis.
