An essential component of business continuity is the ability to quickly replicate data. 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.
Copy-on-Write Snapshot software rapidly creates point-in-time snapshot copies of any data volume within Hitachi storage systems, without impacting host service or performance levels. Since these snapshots only store the changed data blocks in the Copy-on-Write Snapshot storage pool, the amount of storage capacity required for each snapshot copy is substantially smaller than the source volume. As a result, a significant savings is realized when compared with full cloning methods.
This product is enhanced by Hitachi Replication Manager, a new software tool that configures, monitors and manages Hitachi storage system-based replication products for both open systems and mainframe environments in a way that simplifies and optimizes the configuration, operations, task management and automation and monitoring of the critical storage components of the replication infrastructure.
Features
- Point-in-time copies of only changed blocks in Copy-on-Write Snapshot data pool, not full volumes.
- Instantaneous restore of just the data you need.
- Versioning of backups for easy restore.
- RAID protection of all Copy-on-Write Snapshot copies.
- Near instant copy creation and deletion.
- Can be integrated with industry leading backup software applications.
Benefits
- Reduces recovery time from data corruption or human error considerably via an immediate restore from a disk resident, point-in-time data snapshot copy.
- Allows frequent data backup operations to be performed nondisruptively, while critical applications run unaffected.
- Accelerates application testing and deployment by providing always available copies of current production information.
- Enables immediate access to time critical information.
- Eliminates the backup window.
- Improves operational efficiency by allowing multiple processes to run in parallel with access to the same information.
- Allows disk space to be used efficiently through volume snapshots rather than full copy clones, which helps maximize the disk.
