DETERMINING A NUMBER OF STORAGE DEVICES TO BACKUP OBJECTS IN VIEW OF QUALITY OF SERVICE CONSIDERATIONS

摘要

Storage device libraries, machine readable media, and methods are provided for determining a number of storage devices to backup objects in view of quality of service considerations. An example of a storage device library that determines the number of storage devices to backup objects includes a plurality of storage devices and a controller to control backup of the objects to an assigned number of the storage devices. The controller determines the assigned number of the storage devices before the backup of the objects based upon assigned parameters for backup of the objects that include a time window and a number of concurrent disk agents per storage device.
