Publication number: 20220044201Abstract: Systems herein include a managed content application that can place markers for conversations within secure documents. A separate social application can serve as the platform for the conversations, allowing for efficient conversations that can occur in real time. The markers can be stored with the documents and identify the conversation, allowing users to retrieve historical conversations that occurred on the social application from within the document. This can allow users to quickly come up to speed without having to rehash the conversations with the original participants. Document security can also be maintained without sacrificing conversation efficiency of the social application.Type: ApplicationFiled: October 25, 2021Publication date: February 10, 2022Inventors: Gangadhar NITTALA, Ramani Panchapakesan, Arjun Kochhar, Saurabh Agrawal, Akshay Laxminarayan, Ilanchezhian Kuppusamy

Publication number: 20210279141Abstract: Disclosed methods and systems leverage resources in a storage management system to restore a selected backup to a production site. The backup is partitioned into blocks with associated signatures. The production site may have blocks that have not changed from when the backup occurred, so those blocks do not need to be restored. Block signatures from the production site are compared with block signatures from the incremental backup to identify blocks that need to be restored. Efficiency may be achieved by synchronizing the replacement blocks from more easily accessible location where available before synchronizing from less accessible locations. In some embodiments, a user may specify the location of the site with the replacement blocks.Type: ApplicationFiled: January 14, 2021Publication date: September 9, 2021Inventors: Manoj Kumar Vijayan, Saurabh Agrawal

Publication number: 20210173744Abstract: Techniques disclosed herein are well suited to restoring deduplicated backup data from cloud-based storage and from multi-node replicated files systems, and they also improve performance in more traditional data storage technologies. Pre-restore steps include analysis of deduplication indexes to identify data segments that are stored consecutively on storage media. Reading data in aggregate runs of consecutively stored data segments reduces interactions with storage media that hosts the deduplicated data and speeds up retrieval. Parallel reads from multiple storage devices in multi-node replicated file systems also speed up retrieval. An illustrative enhanced media agent pre-fetches data (stored in deduplicated form) in anticipation of read requests that are expected in the restore operation.Type: ApplicationFiled: October 23, 2020Publication date: June 10, 2021Inventors: Saurabh AGRAWAL, Manoj Kumar VIJAYAN

Publication number: 20200293213Abstract: The exemplary system and methods provide a solution for reclaiming the space occupied by invalid blocks of data stored on secondary storage devices. The space reclamation techniques may employ a primary table, a deduplication chunk table, or an index data structure located with the secondary copy of data on secondary storage devices. One exemplary method uses information from the deduplication database media agent and a deduplication chunk table. Another exemplary method uses an index (e.g., single instance file index) that is associated with and stored with each chunk of data. Based on the information provided by the deduplication chunk table and the index, exemplary system and methods identify blocks of invalid data and copy over only valid data blocks to a new container file.Type: ApplicationFiled: March 12, 2020Publication date: September 17, 2020Inventors: Ganesh HARIDAS, Saurabh AGRAWAL, Manoj Kumar VIJAYAN
