Local Replication
The local replication solution delivers convenient and cost-effective local point-in-time data copies using storage-based, space-efficient snapshots and full-volume clones. It generates copies faster and more frequently than host-based solutions, with no impact on production applications. This software bundle includes Hitachi Thin Image Snapshot, Hitachi ShadowImage Replication, and Hitachi Replication Manager software.
- Thin Image
- With Hitachi Thin Image (HTI), you can perform cost-effective replication by storing the differential data between primary volumes (P-VOLs) and secondary volumes (S-VOLs) of virtual volumes (V-VOLs). You can also copy data of an entire volume, instead of copying just the differential data, to a volume. By copying the entire volume, you can expect a higher performance than by just storing the differential data.
