July 8, 2014

By a News Reporter-Staff News Editor at Information Technology Newsweekly -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor Wang, Zhiye (Beijing, CN), filed on December 13, 2012, was made available online on June 26, 2014.

The assignee for this patent application is CA, Inc.

Reporters obtained the following quote from the background information supplied by the inventors: "The present disclosure relates to data recovery, and more specifically, to systems and methods for speeding up data recovery from a server to a client.

"A managed services provider (MSP) may include an information technology (IT) services provider that manages and assumes responsibility for providing a defined set of services to their clients. One such service may include data protection of the client's servers. For example, a MSP may provide a back up system for moving data from the client's servers to a central datastore that is managed by the MSP. Additionally, the MSP may provide a system for data recovery from the MSP datastore to the client's servers. However, the recovery of large amounts of data from the MSP datastore may be slow and inefficient. where the network connection between the MSP and the client's systems is a typical Internet (WAN) connection"

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "In accordance with the present invention, disadvantages and problems associated with previous techniques for data recovery from a MSP to a client system may be reduced or eliminated.

"According to one aspect of the present disclosure, a method for providing recovery from a remote server to a client may be provided. In this method, at least one data restore request is sent to the remote server. A data block identifier are received at the client system via a network. A data block associated with the data block identifier is retrieved from a local backup server associated with the client system if the local back up server stores the data block. The data block associated with the data block identifier is received from the remote server if the local backup server does not store the data block. The data block is restored to the client system.

"Certain embodiments of the invention may provide one or more technical advantages. A technical advantage of one embodiment may be that duplicated data blocks that are stored on the client system may be used during the recovery process. As a result, the amount of data transmitted across a network may be minimized. Another technical advantage of one embodiment may be that a dynamic window scan may be provided to sequentially restore available data blocks while minimizing the amount of time wasted while waiting for unavailable data. Still other advantages may be that the dynamic window scan balances disk access performance and memory usage. As a result, the data recovery performance may be improved. Additionally, the speed with which data may be recovered from the MSP side to the client side may be improved. Still a further advantage may be that data recovery may be effected even over low bandwidth connections between the MSP side and the client side.

"Certain embodiments of the invention may include none, some, or all of the above technical advantages. One or more other technical advantages may be readily apparent to one skilled in the art from the figures, descriptions, and claims included herein.


"Aspects of the present disclosure are illustrated by way of example and are not limited by the accompanying figures with like references indicating like elements.

"FIG. 1 illustrates a diagram depicting a managed services provider (MSP) system for providing data protection services to multiple client systems according to an aspect of the disclosure;

"FIG. 2 illustrates a diagram depicting the state of recovery points of two example client devices before and after a purge operation according to an aspect of the disclosure;

"FIG. 3 illustrates a flowchart depicting a process for providing incremental data restore to a client system according to an aspect of the disclosure; and

"FIGS. 4A-4D illustrate diagrams depicting the various states of an example memory pool of a client system using a dynamic window scan technique for data recovery."
