SnapSAN S3000/S5000 Snapshot User Guide

Version 1

    Snapshot is software for creating replication (snapshot image) at high speed and low cost on a logical disk basis. For snapshot data, only the differential data in the replication source logical disk is retained in storage. Therefore, you can maintain snapshot images with less capacity than the replication source logical disk and use the replication volume at low cost. Snapshot provides basic functions to extend online operation time and support 24-hour operation for 365 days, such as processing data efficiently that increases day to day, and performing online tasks and batch or backup processing in parallel that is performed during the night.This guide assumes that you are familiar with computer hardware, data storage, and network administration terminology and tasks. It also assumes you have basic knowledge of Internet SCSI (iSCSI), Serial-attached SCSI (SAS), Serial ATA (SATA), Storage Area Network (SAN), and Redundant Array of Independent Disks (RAID) technology.
