Publication number: 20220404984Abstract: According to certain aspects, a system includes a client device that includes a virtual machine (VM) executed by a hypervisor, a driver located within the hypervisor, and a data agent. The VM may include a virtual hard disk file and a change block bitmap file. According to some embodiments the driver intercepts write operations generated by the VM to store data in a sector, determines an identity of the sector based on the intercepted write operation, determines an entry in the change block bitmap file that corresponds with the first sector, and modifies the entry in the change block bitmap file to indicate that data in that sector has changed. The data agent may generate an incremental backup of the VM based on the change block bitmap file in response to an instruction from a storage manager, where the incremental backup includes the data in the sector where data was modified.Type: ApplicationFiled: June 30, 2022Publication date: December 22, 2022Inventors: Henry Wallace Dornemann, Rahul S.

Patent number: 11468005Abstract: Virtualization sprawl can lead to virtual machines with no designated periodic backup. If the data associated with these unprotected virtual machines is not backed up, it cannot be restored if needed, leading to system failures. A data storage system identifies and protects the unprotected virtual machines. For instance, the system compares a list of virtual machines with a list of computing devices having a designated backup policy in the data storage system and determines which of the virtual machines are unprotected. The system further automatically categorizes the unprotected virtual machines, identifies those unprotected virtual machines that remain uncategorized, and applies a default backup policy to the uncategorized and unprotected virtual machines to provide protected virtual machines.Type: GrantFiled: July 9, 2020Date of Patent: October 11, 2022Assignee: Commvault Systems, Inc.Inventors: Rahul S. Pawar, Rajiv Kottomtharayil, Parag Gokhale, Sumer Dilip Deshpande, Henry Wallace Dornemann

Patent number: 11436096Abstract: According to certain aspects, a system may include a computing device configured to: intercept a request from a database application to read a portion of a database file, where a secondary copy of the database file resides on a secondary storage device(s) and is organized as a plurality of first blocks, wherein the request includes a database file offset(s) corresponding to the requested portion; and map the database file offset(s) to a subset of the first blocks that correspond to requested database object(s). The system may include a secondary storage controller computer(s) configured to: access a table that maps the plurality of first blocks to storage locations on the secondary storage device(s); using the table, locate and retrieve the subset of the first blocks on the secondary storage device(s); and forward the retrieved first blocks for storage in a primary storage device(s).Type: GrantFiled: December 1, 2020Date of Patent: September 6, 2022Assignee: Commvault Systems, Inc.Inventors: Paramasivam Kumarasamy, Rahul S.

Patent number: 11436038Abstract: Hypervisor-independent block-level live browse is used for directly accessing backed up virtual machine (VM) data. Hypervisor-free file-level recovery (block-level pseudo-mount) from backed up VMs also is disclosed. Backed up virtual machine (“VM”) data can be browsed without needing or using a hypervisor. Individual backed up VM files can be requested and restored to anywhere without a hypervisor and without the need to restore the rest of the backed up virtual disk. Hypervisor-agnostic VM backups can be browsed and recovered without a hypervisor and from anywhere, and individual backed up VM files can be restored to anywhere, e.g., to a different VM platform, to a non-VM environment, without restoring an entire virtual disk, and without a recovery data agent at the destination.Type: GrantFiled: September 21, 2020Date of Patent: September 6, 2022Assignee: Commvault Systems, Inc.Inventors: Henry Wallace Dornemann, Rahul S.

Patent number: 11429499Abstract: An illustrative “VM heartbeat monitoring network” of heartbeat monitor nodes monitors target VMs in a data storage management system. Accordingly, target VMs are distributed and re-distributed among illustrative worker monitor nodes according to preferences in an illustrative VM distribution logic. Worker heartbeat monitor nodes use an illustrative ping monitoring logic to transmit special-purpose heartbeat packets to respective target VMs and to track ping responses. If a target VM is ultimately confirmed failed by its worker monitor node, an illustrative master monitor node triggers an enhanced storage manager to initiate failover for the failed VM. The enhanced storage manager communicates with the heartbeat monitor nodes and also manages VM failovers and other storage management operations in the system. Special features for cloud-to-cloud failover scenarios enable a VM in a first region of a public cloud to fail over to a second region.Type: GrantFiled: July 3, 2020Date of Patent: August 30, 2022Assignee: Commvault Systems, Inc.Inventors: Santhosh Sanakkayala, Sarath Cheriyan Joseph, Ananda Venkatesha, Rajesh Polimera, Rahul S.

Publication number: 20220206907Abstract: Embodiments disclosed herein include systems and processes for replicating one or more user computing systems of an information management system at an external resource system to create a backup or fallback of the user computing systems. Replicating the user computing systems may include replicating data as well as the applications, operating systems and configuration of the user computing systems. This replicated or fallback user computing system may be implemented on a virtual machine at the external resource system. Thus, if a user computing system becomes inaccessible, a new user computing system can be generated based on the backup copy of the user computing system at the external resource system. Further, in some embodiments, the copy of the user computing system may be interacted with at the external resource system. Thus, certain embodiments disclosed herein can be used to transition an information management system to an external resource system.Type: ApplicationFiled: December 14, 2021Publication date: June 30, 2022Inventors: Sri Karthik BHAGI, Sunil GUTTA, Henry Wallace DORNEMANN, Rahul S.

Patent number: 11321190Abstract: An improved content indexing (CI) system is disclosed herein. For example, the improved CI system may include a distributed architecture of client computing devices, media agents, a single backup and CI database, and a pool of servers. After a file backup occurs, the backup and CI database may include file metadata indices and other information associated with backed up files. Servers in the pool of servers may, in parallel, query the backup and CI database for a list of files assigned to the respective server that have not been content indexed. The servers may then request a media agent to restore the assigned files from secondary storage and provide the restored files to the servers. The servers may then content index the received restored files. Once the content indexing is complete, the servers can send the content index information to the backup and CI database for storage.Type: GrantFiled: October 16, 2020Date of Patent: May 3, 2022Assignee: Commvault Systems, Inc.Inventors: Sanath Kumar, Sri Karthik Bhagi, Parag Gokhale, Rahul S.

Publication number: 20210357296Abstract: A system according to certain aspects improves the process of restoring database objects and converting those objects into another database file format. According to certain aspects, a database file is backed up in a block-level fashion. Instead of restoring the entire backup file, the information management system may restore a particular database object from a backup database file that is stored as multiple blocks or other granular units. Then, the information management system can extract the desired data from the restored block(s). By using block-level mapping and storage techniques described herein, the system can restore a database object in a backup database file without restoring the entire backup database file, thereby speeding up restore operations and reducing consumption of storage and processing resources. In addition, the information management system can convert the blocks, using a staging memory, to another database file format as desired.Type: ApplicationFiled: July 28, 2021Publication date: November 18, 2021Inventors: Brahmaiah VALLABHANENI, Paramasivam KUMARASAMY, Rahul S.
