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.

System and method for policy based synchronization of remote and local file systems

A method of managing file permissions in a remote file storage system includes defining permissions for the remote file storage system and controlling access to objects on the remote file storage system according to the permissions of the remote file storage system. The permissions are transferred to a client file storage system remote from the remote file storage system, and access to objects on the client file storage system is controlled according to the permissions of the remote file storage system. A remote file storage system includes a permissions file generator operative to generate a permissions file, which is transmitted to a client file storage system for enforcement at the client file storage system.

Flexible permission management framework for cloud attached file systems

A method for synchronizing a file system (FS) and a remote file system (RFS) includes monitoring the FS for FS events, generating FS event records, receiving RFS event records of RFS events, generating file system operations (FSOs) based on the FS and RFS event records, and communicating the FSOs to the FS and RFS to synchronize them. A method for generating the FSOs includes accessing a plurality of FS and/or RFS event records, processing the accessed records to generate processed event records, generating the FSOs based on the processed event records, and outputting the FSOs to cause synchronization of the FS and RFS. Systems are also described. The invention facilitates event-based, steady-state synchronization of local and remote file systems.

System and method for event-based synchronization of remote and local file systems

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.

Event-based user state synchronization in a local cloud of a cloud storage system

Embodiments offer a cloud system allowing workload management through the use of a zone-compartment architecture. A routing engine extracts an identifier from an incoming request to a cloud system. The routing engine then determines from a mapping in a service mesh, a target compartment corresponding to the identifier. Based upon the target compartment, the routing engine receives an IP address from a registry of the service mesh. Using the IP address, the routing engine routes the request to the target compartment for processing by an application. A database of the target compartment is replicated within another compartment within a different zone, thereby ensuring high availability. Based upon a recommendation provided by the zone, the target compartment may be split or merged to accommodate variations in workflow. The mapping and registry are updated according to changes in the compartments.

Cloud system architecture and workload management

Cloud storage systems and methods provide 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 one of a remote file system (RFS) hosted by the remote cloud storage system and a local file system (LFS) 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.

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.

System and method for synchronizing file systems with large namespaces

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 (RFS) hosted by the remote cloud storage system and a local file system (LFS) 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.
