Patent number: 11880343Abstract: A method and apparatus for replicating a data container of a source storage server at the logical level in an unordered stream of individual data units are described. In certain embodiments, the replication operations can be performed without regard to the differences in geometry of physical persistent storage of the source and destination storage servers and without regard to the differences in data container format of the source and destination storage servers. An initial replication operation of the source data container is performed by transferring the data objects within the source data container to a replica data container in the destination storage server as an unordered stream of individual data units while preserving data object identifiers of the source data objects. Afterwards, incremental replication operations can be performed to capture modifications to the source data container over time after the initial replication operation.Type: GrantFiled: November 30, 2020Date of Patent: January 23, 2024Assignee: NetApp, Inc.Inventors: Bruce Leverett, Michael Kazar, Alan Stuart Driscoll, Peter Frank Corbett, Devang K. Shah, Srishylam Simharajan, Toby Smith

Patent number: 8326798Abstract: A replication operation service migrates data from a source volume having a source file system type to a destination volume having a destination file system type, where the source file system type may be different from the destination file system type. The replication operation is completed without interrupting the operations of a client device in the system. A stable copy of the source file system is generated on the source volume. A file system agnostic representation of a portion of the data in the source volume is generated from the stable copy. The representation is transmitted to the destination volume where it is converted to conform to the destination file system type.Type: GrantFiled: September 14, 2009Date of Patent: December 4, 2012Assignee: Network Appliance, Inc.Inventors: Alan Stuart Driscoll, Peter Frank Corbett, Toby Smith, Devang K.

Patent number: 8078816Abstract: A technique that provides the ability to copy or move a volume that includes one or more quota structures, by using logical replication, where the volume and any quota structures in it are immediately accessible upon completion of the copy/move operation, and where the quota structures' usage control functionality is immediately functional and reliable upon completion of the copy/move operation. A user does not have to reinitialize the quota mechanism or invoke a quota scanner at the destination.Type: GrantFiled: April 7, 2009Date of Patent: December 13, 2011Assignee: NetApp, Inc.Inventors: Omprakaash C. Thoppai, Umeshkumar V. Rajasekaran, Alan Stuart Driscoll, Devang Shah
