ABSTRACT:
The present invention discloses a virtual tape library (VTL) backup system, and a method of hard disk drive (HDD) power control in VTL devices. In the VTL backup system, a disk control module (DCM) is added to the VTL device and an agent module is added to the backup server. When a backup or disaster recovery (DR) operation is triggered, the agent module in the backup server can inform the disk control module (DCM) in the VTL device to trigger the VTL device to power on all the HDDs before the operation starts, and to power off all the HDDs after the operation ends. Power saving in the VTL device is achieved through power control over the HDDs.
