Description
The two mid-range models — the GR720 and the GR730 — and the enterprise model — the GR740 — came with an advanced copy function that accelerated online backups of data between disks within a unit. This function benefited system operation because it could shorten the backup window*1 by accelerating the copying or backup of data in use by services. The advanced copy function also greatly reduced recovery times when data were lost by a malfunction or other cause, since backed up data could be restored almost immediately.
