Publication number: 20140365539Abstract: A method and system for performing data manipulation on a storage device is disclosed. A data manipulation command is created on a computing device, wherein the computing device is separate from the storage device. The computing device is a client or a server that requests services of a storage system to store data on a storage medium. The computing device and the storage device are connected over a network. The computing device executes a host application, and its data is stored on the medium. The computing device issues a command to the storage device to be performed on the data. The storage device executes the command and sends the result to the computing device. As a result, the data is not sent to the computing device for manipulation.Type: ApplicationFiled: April 29, 2014Publication date: December 11, 2014Applicant: NetApp, Inc.Inventors: Don Alvin Trimmer, Sandeep Yadav, Pratap Singh

Patent number: 7882081Abstract: A system for the storage and retrieval of data files includes a data disk, a configuration disk and a controller. Each data file includes one or more data blocks, each data block comprising a data section. The data disk stores the data blocks and is divided into a plurality of block groups. The configuration disk stores a copy of at least a portion of the corresponding meta-data. The controller controls both the data disk and the configuration disk.Type: GrantFiled: August 30, 2002Date of Patent: February 1, 2011Assignee: NetApp, Inc.Inventors: Roger Keith Stager, Don Alvin Trimmer, Craig Anthony Johnston, Yafen Peggy Chang, Jerry Kai Lau

Patent number: 7797582Abstract: A method for tracking changes on a primary volume in a continuous data protection system writes data to the primary volume. A copy of the data is written to a secondary volume, the secondary volume including all writes made to the primary volume. Each write made to the secondary volume is mapped in a data structure, such that the data structure tracks changes on the primary volume between two different points in time.Type: GrantFiled: August 3, 2007Date of Patent: September 14, 2010Assignee: NetApp, Inc.Inventors: Roger Keith Stager, Don Alvin Trimmer, Pawan Saxena, Randall Johnson, Craig Anthony Johnston, Yafen Peggy Chang, Rico Blaser

Patent number: 7567993Abstract: The invention is a method and system for copying backup data to a virtual tape library (VTL), where data written to the VTL can optionally be stored on removable disk media for offsite storage. The invention minimizes dependency on tape media without taxing the resources of any of the servers and without the need for the data protection application (DPA) to perform a second backup pass. Backup data written to the VTL can optionally be copied to the VTL's default storage area and/or to a predetermined set of disks that may be removed and stored offsite.Type: GrantFiled: December 9, 2002Date of Patent: July 28, 2009Assignee: Netapp, Inc.Inventors: Don Alvin Trimmer, Roger Keith Stager, Craig Anthony Johnston, Yafen Peggy Chang, Rico Blaser

Patent number: 7487009Abstract: The present invention is a tape library comprising both a small front-end portion and a larger back-end portion. The front-end portion is a visible virtual or physical tape library; and the back-end portion is a large invisible virtual or physical tape vault. The DPA is a typical DPA which only sees the front-end library. If desired, all messages regarding the importing and exporting of tapes are reviewed by an agent. The agent manages the automatic transfer of tapes between the front-end and the back-end, and notifies the user when a manual import or export is needed. This greatly reduces both the amount of hardware required to establish a virtual or physical tape library and also reduces the amount of labor required by a user to physically import and export tapes. If both the front-end library and the back-end vault are virtual and reside on the same virtual tape library appliance, no data movement is necessary and the tapes can be moved merely by performing small software state changes.Type: GrantFiled: December 6, 2005Date of Patent: February 3, 2009Assignee: Netapp, Inc.Inventors: Don Alvin Trimmer, Roger Stager, Craig Anthony Johnston, Rico Blaser

Patent number: 7437492Abstract: A method and system for efficiently storing and transferring data in a virtual tape library environment is disclosed. Data is written to a virtual tape library that emulates a physical tape library. Data stored in the virtual tape library may be compressed and an estimated compression ratio may be dynamically computed. While data is written to the virtual tape library, an end-of-tape signal is provided based on the estimated compression ratio.Type: GrantFiled: May 14, 2003Date of Patent: October 14, 2008Assignee: Netapp, IncInventors: Roger Stager, Don Alvin Trimmer, Craig Anthony Johnston, Rico Blaser

Patent number: 7437387Abstract: A method and system wherein a plurality of different file system views may be provided for the same data. Data copied in a sequential format to a disk based repository using a data protection application is decoded so that the data may be presented and accessed using a standard file system view. The standard file system may be used to randomly access the data as desired.Type: GrantFiled: August 30, 2002Date of Patent: October 14, 2008Assignee: Netapp, Inc.Inventors: Gavin David Cohen, Don Alvin Trimmer, Rico Blaser
