Data utilized in daily business is exposed to risk of being lost due to a system failure or natural disaster, etc. To protect the data from such risk and ensure business continuity, secure data backup is necessary. In addition, also from a compliance perspective, long-term data storage is demanded.

HS Series is the next-generation secondary storage based on advanced grid storage technology, which is different from the conventional tape-based backup and disk-based backup.
Disk-based backup products aim to achieve both the high-speed processing capability of disk and a cost advantage that is equivalent to the cost advantage gained by tape-based backup. They are suitable for backing up data that can be highly compressed or data that requires generation management, as well as for storing data for a long period of time. By replicating the compressed data to a remote location, measures against disasters can be taken at a low network cost.
The grid architecture, which joints multiple nodes in a mesh shape, allows you to add nodes without stopping the system, and freely scale up the processing capability and memory capacity. In addition, with the "automatic optimal configuration" feature, data migration for added nodes and deleted nodes is automatically reconfigured. These technologies enable system update with fewer man-hours compared to when replacing with new storage.
