Patent number: 11907359Abstract: Cloud storage systems and methods are described for providing event-based user state synchronization among the various cloud elements. A global user directory is maintained on a remote cloud storage system. The global user directory includes a plurality of global user definitions associated with a plurality of user accounts, where each of the user accounts has access to at least one of a remote file system hosted by the remote cloud storage system and a local file system hosted by a local cloud storage system. As global user definition are altered on the remote cloud storage system, user events are generated and communicated to the local cloud storage system, where they are applied to synchronize the local user definitions with the global user definitions. The invention facilitates centralized control of user definitions, near real-time event delivery to local cloud storage systems, and separation of authentication processes from customers' active directory services.Type: GrantFiled: August 18, 2022Date of Patent: February 20, 2024Assignee: Egnyte, Inc.Inventors: Shishir Sharma, Debjit Bhattacharjee, Amrit Jassal, Kalpesh Patel, Deepak Mehta, Przemek Grzedzielski, Sachin Shetty, Krzysztof Gardo, Daniil Iaitskov, Harikesavan Krishnan, Manish Marathe

Publication number: 20230325360Abstract: A method for synchronizing a local file system (LFS) and a remote (cloud) file system (RFS) includes the step of storing events indicative of differences between the LFS and the RFS, where the events are associated with file system objects of the LFS and RFS. The method further includes the steps of prioritizing the events, generating file system operations for the events based at least in part on the prioritization of the events, and performing at least some of the file system operations to synchronize the LFS and RFS. Prioritizing the events includes defining a plurality of service classes (e.g., based on type of event, event attribute, etc.), assigning a priority to each of the service classes, and assigning each event to one of said service classes. Systems are also described. The invention allocates limited synchronization resources based on a predefined policy to synchronize important file system objects sooner.Type: ApplicationFiled: April 10, 2023Publication date: October 12, 2023Applicant: Egnyte, Inc.Inventors: Ravi Wijayaratne, Remus Koos, Ray White, Manish Marathe, Dmitry Tisnek, Harikesavan Krishnan, Amrit Jassal

Publication number: 20220335011Abstract: A novel method for restarting a steady-state synchronization process includes persisting synchronization data in non-volatile memory before restarting, and utilizing the persisted synchronization data to restart the synchronization where the prior steady-state synchronization process left off. In a particular embodiment, the synchronization data is indicative of a particular point of the synchronization process and is utilized to begin synchronizing from that point after the service is restarted. In a more particular embodiment, the synchronization data is a particular operation of a sequence of operations performed as part of the synchronization. In another particular embodiment, operations associated with a batch are applied before stopping the synchronization.Type: ApplicationFiled: April 29, 2022Publication date: October 20, 2022Inventors: Remus Koos, Tal Broner, Harikesavan Krishnan

Patent number: 10437789Abstract: The invention prevents improper deletes of file system objects during rescan synchronizations of local and remote (cloud) file systems. File and folder deletes are validated (confirmed) during a rescan synchronization using events generated for a steady state synchronization process. Any improper deletes are fenced and not allowed to proceed during synchronization. A method for synchronizing local (LFS) and remote (RFS) file systems includes monitoring the LFS for changes, generating a first set of events as part of a first synchronization routine (e.g., a steady state synchronization routine), generating a second set of events as part of a second (rescan) synchronization routine, validating selected events of the second set with events of the first set to determine whether each of the selected events of the second set is valid or invalid, and synchronizing the file systems based on the events of the second set excluding those that have been invalidated. Storage systems are also disclosed.Type: GrantFiled: April 8, 2016Date of Patent: October 8, 2019Assignee: Egnyte, Inc.Inventors: Remus Koos, Ravi Wijayaratne, Manish Marathe, Ray White, Dmitry Tisnek, Roman Levin, Harikesavan Krishnan, Hakan Ancin, Purvi Talati
