Often the first line of defense against data corruption or data loss is having a usable clone or copy of the data you've just lost. The most successful techniques leverage array-based in system data replication, a critical component of any data protection infrastructure. The Hitachi In System Replication bundle combines our full clone replication software Hitachi ShadowImage In System Replication Software and our snapshot solution, Hitachi Copy-On-Write Snapshot Software.
ShadowImage provides a nondisruptive, host-independent data replication solution for creating copies of any customer accessible data within a single Hitachi storage system. All copies are additionally RAID-protected to ensure the highest data availability.
Hitachi Copy-on-Write Snapshot software provides logical snapshot data replication within Hitachi storage systems for immediate use in decision support, software testing and development, data backup, or rapid recovery operations.
Features
- High-speed nondisruptive full volume local mirroring technology of Hitachi ShadowImage In-System Replication software rapidly creates multiple copies of mission-critical information within all Hitachi storage systems in mainframe and open systems environments.
- ShadowImage software keeps data RAID-protected and fully recoverable-without affecting service or performance levels.
- ShadowImage replicated full data volumes can easily be split from the host applications
- Copy-On-Write provides point-in-time copies of only changed blocks in Copy-on-Write Snapshot data pool, not full volume.
- Copy-On-Write also delives instantaneous creation and restore of just the data you need with versioning of backups for easy restore.
Benefits
- ShadowImage Shortens restart and recovery times with the consistency-group function, which provides multivolume, point-in-time copies for applications and databases that share or span multiple volumes.
- Shadow Image Reduces recovery from data corruption time dramatically through the ShadowImage QuickRestore feature, which allows an immediate restore to a disk-resident, point-in-time data copy.
- Copy-On-Write reduces recovery time from data corruption or human error considerably via an immediate restore from a disk-resident, point-in-time data snapshot copy.
- Copy-On-Write also allows disk space to be used efficiently through volume snapshots rather than full-copy clones, which helps maximize disk.
Quote
"With transaction volume surging year after year,
we identified a strong need for an enterprise-class
integrated storage system and a need for efficient
back-up of data. Therefore, we decided to promote
integrated disk management and introduction of
internal data replication function."
