Filed:

Jul 8, 2003

Appl. No.:

10/616411

Inventors:

John Guthrie - Woodinville WA, US

International Classification:

G06F017/00

US Classification:

707104100

Abstract:

A method and system for creating a snapshot of data. The snapshot system creates a snapshot of data that is hierarchically organized, such as the data of a file system. When a snapshot is to be created, the snapshot system copies the root node of the hierarchical organization to a new root node that points to the same child nodes as the copied root node. This new root node becomes the root node of the snapshot data. When a current node is subsequently modified, the snapshot system replaces each ancestor node of that node that has not yet been replaced with a new node that has the same child nodes as the replaced node. The snapshot system also replaces the node to be modified with a new node that points to the same child nodes of the replaced node.

Abstract:

A method and system for facilitating digital commerce using a secure digital commerce system is provided. The secure digital commerce system is arranged according to a client/server architecture and includes a modularized DCS client and DCS server. The DCS client and the DCS server are incorporated into an online purchasing system, such as a virtual store, to perform the purchase and online delivery of electronic content. The DCS client includes a set of components which include a secured copy of the merchandise and various components needed to license and purchase the merchandise and to unsecure and process (e.g., execute) the licensed merchandise. The DCS client communicates with the DCS server to download the components onto a customer's computer system and to license and purchase a requested item of merchandise. The DCS server, which includes a content supplier server, a licensing and purchasing broker, and a payment processing function, supplies merchandise-specific components and licenses the requested item of merchandise by generating an electronic certificate. The electronic certificate contains license parameters that are specific to the requested merchandise and an indicated purchasing option. Once a valid electronic license certificate for the requested merchandise is received by the DCS client, the merchandise is made available to the customer for use in accordance with the licensing parameters contained in the electronic license certificate.

Inventors:

John Guthrie - Monroe WA, US

Assignee:

Zetta Systems, Inc. - Woodinville WA

International Classification:

G06F012/00

US Classification:

707200000

Abstract:

A block level data snapshot system uses agents to convert block level file commands from devices such as computer workstations intended for block level devices such as hard disks. The block level file commands are converted into instructions for a node based snapshot data system for taking snapshots at the block level. By converting the block level file commands into instructions suitable for the node based snapshot system, snapshots are able to be taken at the block level, which allows for disk storage savings and speed enhancements. One resultant feature is that the block level data snapshot system can be used as a block level storage device for one or more workstations thus allowing relatively simple integration of a snapshot system with existing workstations.
