Disk distribution system
First Claim
1. A disk distribution system comprising at least one master server that is connected with a plurality of terminals through a network,the disk distribution system includingan OS image data as master data, the master data being managed by the master server, anda copy of the master data as a boot image for the terminals,the terminals receiving differential data reflecting an update to the master data through the network from the master server while the terminals are operating, and each boot image of each terminal being updated based on the received differential data by rebooting each terminal,each terminal provided with a difference management mechanism that stores, as data relative to the boot image, at least any ofunique data including a host name and an IP address of the terminal,write data to the terminal, andconfiguration information of a device driver,wherein the OS image data is in Out-Of-Box Experience (OOBE) state as a boot image for the terminals, and the differential data includessetup data relative to the boot image, the setup data providing a customization from the OOBE state for the terminal andrestoration data for, after the customization provided by the setup data, restoring the boot image for the terminal into OS image data in the OOBE state again, andwherein each terminal stores a separate copy of the master data as a boot image for the terminal, the differential data reflecting an update to the master data, and the data relative to the boot image, even after the boot image is updated by rebooting the terminal.

Abstract
A disk distribution system, assuming “local-boot”, that is capable of efficiently executing an update or a generation management of OS image data. The disk distribution system includes at least one master server that is connected with a plurality of terminals through the network, in which OS image data including an operating system for the terminals is processed as the master data managed by the master server, and a copy of the data for a copy of the data converted into a predetermined format) is deployed as a boot image for the terminals. When the master data is updated, the terminals receive differential data reflecting the update to the master data through the network from the master server while the terminals are operating, and the boot images of the terminals are updated by rebooting the terminals.
