Publication number: 20240118976Abstract: Described is a system for management of specialized files used for a backup restore. The system may allow for an automated recovery to be performed without having to manually identify critical information required to perform a restore of a particular backup within a backup chain. This information may include a control file and a parameter file. A backup agent may store such information within specialized objects that are stored as part of metadata managed by a backup agent to provide an additional layer of recover capability and efficiency. This information may then be leveraged for retrieval during a restore operation, for example, in a disaster recovery scenario.Type: ApplicationFiled: October 10, 2022Publication date: April 11, 2024Applicant: Dell Products L.P.Inventors: Shraddha Chunekar, Navneet Upadhyay, Iresha Gadikar, Amith Ramachandran, Haritha Kora, Rejith Mohan M

Patent number: 11836050Abstract: Techniques described herein relate to a method for generating synthetic full backups. The method may include obtaining a snapshot associated with a previous backup stored in a data domain; obtaining a second snapshot associated with a current state of the source data; generating a snapshot difference report using the first snapshot and the second snapshot and including a delete list, a rename list, and a copy list; storing a copy of the previous backup in the data domain; performing a delete operation on the copy based on the delete list; performing a rename operation on the copy based on the rename list; and performing a copy operation based on the copy list. In one or more embodiments, performing the delete operation, the rename operation, and the copy operation on the copy of the previous backup generates a first synthetic full backup of the source data.Type: GrantFiled: September 30, 2021Date of Patent: December 5, 2023Assignee: EMC IP HOLDING COMPANY LLCInventors: Shraddha Chunekar, Navneet Upadhyay, Deepthi Urs, Sunder Ramesh Andra, Amith Ramachandran, Adrian Dobrean

Patent number: 11593219Abstract: A method and system for auto live-mounting database golden copies. Specifically, the disclosed method and system entail reactively auto live-mounting golden copy databases on hosts or proxy hosts based on the operational state of one or more database hosts and/or one or more assets (or databases) residing on the database host(s). Should a database host prove to be unresponsive, through periodic monitoring, databases residing on the database host may be brought back online on a proxy database host using stored golden copies respective of the aforementioned databases. Alternatively, should a given database on any database host exhibit an operational abnormality (e.g., an error, failure, etc.), the given database may be brought back online on the database host or a proxy database host using a stored golden copy respective of the given database. Accordingly, through the disclosed method and system, database outages may be minimized.Type: GrantFiled: September 6, 2019Date of Patent: February 28, 2023Assignee: EMC IP Holding Company LLCInventors: Navneet Upadhyay, Shraddha Chunekar, Haritha Kora, Shelesh Chopra, Amith Ramachandran

Patent number: 11593226Abstract: A backup manager for managing backup services includes persistent storage and a backup analyzer. The persistent storage includes a backup data repository and protection policies. The backup analyzer identifies a new backup stored in backup storage; performs a backup compatibility analysis on the new backup to determine inter-backup compatibility of the identified new backup; updates the backup data repository based on the inter-backup compatibility to obtain an updated backup data repository; and modifies a backup schedule using the updated backup data repository to meet a requirement of a protection policy of the protection policies.Type: GrantFiled: November 1, 2019Date of Patent: February 28, 2023Assignee: EMC IP Holding Company LLCInventors: Asif Khan, Amith Ramachandran, Amarendra Behera, Deepika Nagabushanam, Ashish Kumar, Pati Mohan, Tushar Dethe, Himanshu Arora, Gururaj Soma, Sapna Chauhan, Soumen Acharya, Reshmee Jawed, Yasemin Ugur-Ozekinci, Shelesh Chopra, Navneet Upadhyay, Shraddha Chunekar
