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: 20220147488Abstract: A method for facilitating synchronization of a remote file system (RFS) and a local file system (LFS) includes maintaining a global revision identifier associated with the RFS, where the global revision identifier has a variable state, and responsive to the RFS being modified, updating metadata associated with one or more of the file system objects of the RFS based on a state of the global revision identifier. More particularly, the method includes updating the global revision identifier to a new state in response to the RFS modification and then updating the metadata of the folder(s) associated with the RFS modification. The RFS metadata is partitioned by folder and file to facilitate efficient searching based on a requested namespace view. Another method utilizes prior revision identifiers stored in the LFS to limit the RFS metadata returned to the local cloud during a rescan, by excluding the data set that has not changed, which improves the efficiency of the rescan synchronization.Type: ApplicationFiled: September 21, 2021Publication date: May 12, 2022Applicant: Egnyte, Inc.Inventors: Shishir Sharma, Manish Marathe, Amrit Jassal, Hakan Ancin, Dmitry Tisnek

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
