Publication number: 20240111712Abstract: File system data that was backed up from a source system to a storage system is determined to be archived. The storage system maintains a tree data structure that enables the backed up file system data to be located. A portion of the tree data structure and the file system data are serialized into a first flat set of data. A first data block associated with the first flat set of data includes a file offset to a first data block associated with a second flat set of data corresponding to a previous archive of the file system data. The first flat set of data is archived to an archival storage.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Inventors: Venkata Ranga Radhanikanth Guturi, Tushar Mahata, Praveen Kumar Yarlagadda

Patent number: 11880334Abstract: At least a portion of data of a tree data structure is serialized into a first set of flat data. At least a portion of a structure of the tree data structure is serialized to reproduce at least the portion of the structure in a second set of flat data. It is determined to access a desired data of the tree data structure from an archive. The second set of flat data is read to reconstitute at least the portion of a structure of the tree data structure. The reconstituted structure of the tree data structure is used to determine a data offset associated with the first set of flat data, wherein the data offset corresponds to the desired data. The desired data is accessed using the data offset associated with the first set of flat data.Type: GrantFiled: January 6, 2022Date of Patent: January 23, 2024Assignee: Cohesity, Inc.Inventors: Venkata Ranga Radhanikanth Guturi, Tushar Mahata, Praveen Kumar Yarlagadda

Patent number: 11874805Abstract: A request to access one or more files associated with a particular pint in time that are archived at a cloud storage is received. A file system metadata tree data structure based on metadata associated with the one or more requested files that is obtained from the cloud storage is partially restored at a storage system. The partially restored file system metadata tree data structure includes one or more stub nodes associated with one or more non-requested files. Access to the one or more requested files is provided using the partially restored file system metadata tree data structure. Metadata associated with the one or more non-requested files is prefetch from the cloud storage. A portion of the file system metadata tree data structure corresponding to the one or more non-requested files is restored in part by replacing the one or more stub nodes associated with the one or more non-requested files with metadata corresponding to the one or more non-requested files.Type: GrantFiled: May 18, 2022Date of Patent: January 16, 2024Assignee: Cohesity, Inc.Inventors: Venkata Ranga Radhanikanth Guturi, Tushar Mahata, Praveen Kumar Yarlagadda

Patent number: 11861392Abstract: An instruction to generate a cloud instantiation of a secondary storage system is provided. One or more secondary storage clusters are virtually rebuilt in the cloud instantiation of the secondary storage system. A new cloud instance of a user virtual machine is deployed based on at least a portion of data stored in the one or more rebuilt secondary storage clusters of the cloud instantiation of the secondary storage system. A version of at least the portion of the data of the one or more rebuilt secondary storage clusters is provided to a cloud deployment server.Type: GrantFiled: December 15, 2022Date of Patent: January 2, 2024Assignee: Cohesity, Inc.Inventors: Venkata Ranga Radhanikanth Guturi, Tushar Mahata, Praveen Kumar Yarlagadda, Vipin Gupta

Patent number: 11782649Abstract: A list of one or more archives available to be restored is provided to an authenticated user. The list of one or more archives available to be restored is based in part on a credential provided by the authenticated user. The credential provided by the user is linked to a subset of a plurality of snapshot archives associated with an enterprise. A selection of one of the one or more archives and an external target for the selected archive is received. A cloud instantiation of a secondary storage system is utilized to reconstitute a tree data structure based on serialized data included in the selected archive. A request to restore data associated with the selected archive to the external target is received. The requested data associated with the archive is provided to the external target.Type: GrantFiled: May 9, 2022Date of Patent: October 10, 2023Assignee: Cohesity, Inc.Inventors: Venkata Ranga Radhanikanth Guturi, Tushar Mahata, Praveen Kumar Yarlagadda

Patent number: 11372824Abstract: Metadata of a root node from a serialized representation of a file system metadata tree data structure is obtained. A representation of the root node that references a stub intermediate node that is a placeholder for an intermediate node stored in the serialized representation is created. A request to access data of a leaf node in a tree path including the intermediate node is received. In response to the request, metadata of the intermediate node is obtained from serialized metadata representation.Type: GrantFiled: June 10, 2020Date of Patent: June 28, 2022Assignee: Cohesity, Inc.Inventors: Venkata Ranga Radhanikanth Guturi, Tushar Mahata, Praveen Kumar Yarlagadda
