Patent number: 11829630Abstract: Described is a system (and method) for providing multiple types of granular delete operations for a cloud-based object storage. The system may include a server that acts as an intermediary between a client device and an object storage that stores client data. The server may allow a client to perform a hard delete (or permanent) delete and a soft delete. The server may perform a specialized processing to synthetically create the soft delete feature using a permanent object delete operation provided by the object storage. The specialized processing may include manipulating retention periods associated with objects depending on whether the object is subject to a hard delete or a soft delete.

Patent number: 11809280Abstract: Described is a system for synchronizing expiration times for incremental backup data stored on a cloud-based object storage. More particularly, the system may provide a layer of intelligence when updating the expiration times associated with backup data to ensure that a full recovery of the client data to a point-in-time of any incremental backup may be performed. To provide such a capability, the system may maintain specialized metadata identifying expiration times for objects and a list of objects required to perform a full recovery to a point-in-time for each of the performed backups (e.g. full or incremental). The system may access this metadata to identify which objects stored by a previous backup are still referenced by a subsequent backup. Based on the identified objects, the system may synchronize object expiration times to ensure objects are not prematurely deleted from the object storage.Type: GrantFiled: March 5, 2021Date of Patent: November 7, 2023Assignee: EMC IP Holding Company LLCInventors: Shelesh Chopra, Sunil Yadav, Amarendra Behera, Ravi Vijayakumar Chitloor, Tushar Dethe, Himanshu Arora, Prabhat Kumar Dubey, Jigar Bhanushali, Deependra Singh

Patent number: 11669404Abstract: Described is a system (and method) for efficient access-based reallocation of backup data stored within an object storage. The system may implement various specialized procedures to efficiently store and manage backup data within the object storage. These procedures may include packing backup data into objects to improve data operation efficiency. The system may also conserve storage space on the object storage by performing an analysis to reallocate backup data as necessary. For example, data may be stored in objects in an immutable manner, and thus, the system may efficiently reallocate data to new objects based on data access patterns. For example, the system may determine an access pattern associated with live data remaining within the first object satisfies a condition, and in response, reallocated the live data to a new object.Type: GrantFiled: July 13, 2021Date of Patent: June 6, 2023Assignee: EMC IP Holding Company LLCInventors: Sunil Yadav, Ravi Vijayakumar Chitloor, Shelesh Chopra

More specifically, the system may re-tier objects such that the system retains the ability to efficiently perform a full restore of backup data even when incremental backups are performed to a cloud-based object storage. To provide such a capability, the system may maintain a specialized metadata database that stores information indicating the backup time for each backup, and a list of objects required to perform a full restore to each of the backup times. Accordingly, when using a threshold time (e.g. expiry) to select object candidates for re-tiering, the system may leverage the metadata database to ensure that objects that may still need to be referenced are not unnecessarily moved to a lower storage tier.Type: GrantFiled: January 15, 2021Date of Patent: June 6, 2023Assignee: EMC IP Holding Company LLCInventors: Ravi Vijayakumar Chitloor, Sunil Yadav, Shelesh Chopra, Amarendra Behera, Tushar Dethe, Deependra Singh, Prabhat Kumar Dubey, Himanshu Arora, Jigar Bhanushali

Patent number: 11669405Abstract: Described is a system for managing the expiration of objects storing incremental backup data by leveraging specialized metadata. The system may provide a layer of intelligence when freeing up storage space on an object storage to ensure that a full recovery of client backup data may be performed when storing incremental backup data. The system may maintain metadata indicating the latest and/or earliest backups that reference particular objects. The system may then leverage this information to mark particular objects for removal (e.g. deletion or re-tiering). For example, the system may access the metadata to identify which objects stored by a previous (e.g. expired) backup are still referenced by a subsequent (e.g. non-expired) backup. As a result, the system may ensure that objects are not removed prematurely and that a full recovery of the client data to a point-in-time of any incremental backup may be performed.Type: GrantFiled: July 13, 2021Date of Patent: June 6, 2023Assignee: EMC IP Holding Company LLCInventors: Sunil Yadav, Shelesh Chopra, Ravi Vijayakumar Chitloor
