Patent number: 11659064Abstract: An improved information management system that implements a staging area or cache to temporarily store primary data in a native format before the primary data is converted into secondary copies in a secondary format is described herein. For example, the improved information management system can include various media agents that each include one or more high speed drives. When a client computing device provides primary data for conversion into secondary copies, the primary data can initially be stored in the native format in the high speed drive(s). If the client computing device then submits a request for the primary data, the media agent can simply retrieve the primary data from the high speed drive(s) and transmit the primary data to the client computing device. Because the primary data is already in the native format, no conversion operations are performed by the media agent, thereby reducing the restore delay.Type: GrantFiled: October 11, 2021Date of Patent: May 23, 2023Assignee: Commvault Systems, Inc.Inventors: Ramachandra Reddy Ankireddypalle, Manoj Kumar Vijayan, Pratima Bapusaheb Kudale, Anuradha Talur, Manivannan Subramaniam

Patent number: 11614879Abstract: A technique replicates an index of an operations log (oplog) from a primary node to a secondary node of a cluster in the event of failure. The oplog functions as a staging area to coalesce random write operations directed to a virtual disk (vdisk) stored on a backend storage tier. The oplog temporarily caches write data as well as metadata describing the write data. The metadata includes descriptors to the write data corresponding to offset ranges of the vdisk and are used to identify ranges of write data for the vdisk that are cached in the oplog. To facilitate fast lookup operations of whether write data is cached in the oplog, an oplog index provides a state of the latest data for offset ranges of the vdisk that enables fast failover of metadata used to construct the oplog index in memory without downtime or significant metadata replay.Type: GrantFiled: March 31, 2021Date of Patent: March 28, 2023Assignee: Nutanix, Inc.Inventors: Alok Nemchand Kataria, Niranjan Sanjiv Pendharkar, Pete Wyckoff, Rishi Bhardwaj, Rohit Jain, Shubham Shukla, Tabrez Parvez Memon

Patent number: 11516050Abstract: Technologies are disclosed for monitoring network traffic using traffic mirroring. According to some examples, traffic mirroring allows customers to monitor traffic at different sources within a VPC. For example, a source may be any Elastic Network Interface (ENI) in their VPC, including elastic network interfaces (ENIs) on virtual machine instances, Network Address Translation (NAT) Gateways, Load Balancers, VPC endpoints, Internal Gateways, Transit Gateways, and more. Filters can be utilized to determine the network traffic to mirror. A customer may also configure to monitor real-time traffic with a monitoring appliance of their choice. With traffic mirroring, data traffic may be identified and sent to one or more target devices. Customers may monitor traffic within a VPC for content inspection, forensic analysis, troubleshooting, record keeping, and the like.Type: GrantFiled: September 23, 2019Date of Patent: November 29, 2022Assignee: Amazon Technologies, Inc.Inventors: Anoop Dawani, Joseph Elmar Magerramov, Zachary Brandes, Apoorv Mittal, Bharadwaj Avva, Ryan James Schaefer, Kiran Venkat Sayeeram Karpurapu, Ajay Jha, Steven Bruce Richards, Richard H Galliher

Patent number: 11500814Abstract: Techniques and mechanisms described herein facilitate the execution of a software program container having a plurality of layers. Each layer may include a plurality of files. For instance, a base layer may include a version of an operating system, while an upper layer may include a software program configured to run within the operating system. Different layers may store, create, or modify the same file. However, the precedence of the version of the data for the file may be based on an ordering of the layers. For example, the version of the file in a higher layer should supersede the version of the file in a lower layer. In some implementations, a privileged storage container that runs atop a virtualization layer may manage storage resources for other containers. The privileged storage container may store each file in a software program container as a snapshotable object.Type: GrantFiled: November 4, 2020Date of Patent: November 15, 2022Assignee: Pure Storage, Inc.Inventors: Goutham Rao, Vinod Jayaraman

Patent number: 11467915Abstract: A backup manager for providing backup services includes storage and a backup orchestrator. The persistent storage stores prediction models. The backup orchestrator obtains a computing resource availability for a client; generates a prediction model of the prediction models using the computing resource availability for the client; predicts, using the prediction model and live data, a future computing resource availability for the client; and initiates generation of a backup for the client at an unscheduled time that is based, at least in part, on the future computing resource availability.Type: GrantFiled: October 18, 2019Date of Patent: October 11, 2022Assignee: EMC IP Holding Company LLCInventors: Sujan Kumar Shetty, Prasanth Balasubramanian, Sushanth Shet, Shelesh Chopra, Jaishree Balasubramanian

Patent number: 11461202Abstract: A remote data replication method and a storage system, where a production array sends a data replication request to a disaster recovery array. The data replication request includes an identifier of a source object and a data block corresponding to the source object. The data block is stored in physical space of a hard disk of the production array. The disaster recovery array receives the data replication request. The disaster recovery array creates a target object when the disaster recovery array does not include an object having a same identifier as the source object. An identifier of the target object is the same as the identifier of the source object, the disaster recovery array writes the data block into the physical space.Type: GrantFiled: August 11, 2020Date of Patent: October 4, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Ji Ouyang, Huabing Yan

Patent number: 11379314Abstract: The present disclosure relates to a method, device and computer program product for managing a backup job. Specifically, there is provided a method for managing a backup job, the backup job being used to store a data object to a storage system. In the method, the difference between the data object specified by the backup job and a copy of the data object in the storage system is determined. In response to determining the difference meets a predetermined threshold, a difference area in the data object where there might exist the difference is determined. With respect to a first block within the difference area, in a group of blocks in the data object, the backup job is processed based on a first query result from the storage system, the first query result indicating whether data in the first block differs from data in a corresponding block in the copy.Type: GrantFiled: February 19, 2020Date of Patent: July 5, 2022Assignee: EMC IP Holding Company LLCInventors: Yi Wang, Qingxiao Zheng, Lanjun Liao

Patent number: 9026750Abstract: Improved data management systems for managing and maintaining unstructured data in a computing system environment. Data content is associated with particular types of metadata to create data objects. In certain examples, the metadata is stored in various fields of the data objects, certain fields being designated as permanently read-only after their creation. Such fields can include, for instance, a unique identifier, a type of content and a classification governing copy permissions relating to the data object. Data objects, or didgets, can be grouped into logical containers referred to as chambers, which are further grouped by common control elements or attributes into domains. Chambers within a particular domain can generally freely share information therebetween, including copies of various types of didgets. A control program, or didget manager, in each domain manages the creation of didgets and subsequent operations directed thereto.Type: GrantFiled: December 17, 2014Date of Patent: May 5, 2015Inventor: Andy Vincent Lawrence
