    摘要： Methods in a cloud object store facilitate strong data encryption, customer-management of object (encryption) keys, reductions in latency, globally-distributed object storage, and handling of streamed uploads. A method for encrypting objects stored in a cloud includes encrypting each object with a unique encryption (object) key. The plaintext object keys are generated in advance of uploads. The plaintext object keys can be stored in an object database in the cloud. Alternatively, the plaintext object keys can be provided to a customer's HSM, encrypted, and returned to the cloud, such that encrypted object keys, encrypted by the customer, are stored in the cloud. The cloud can alternatively encrypt the customer's object keys with a master key for the customer, which is then encrypted by the customer's HSM before being stored in the cloud. Proxies are also deployed for efficiently communicating with customer security modules.

    摘要： 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.

    摘要： A cloud-based data governance system includes a processing unit, a network adapter, and memory for storing data and code. The network adapter establishes a connection with a remote data storage system associated with a remote file system over a wide-area network (WAN). The code includes an event collection interface, a data governance service, and an enforcement service. The event collection interface is configured to capture an event from the remote data storage system. The event is indicative of a file system operation executed on a data object of the remote file system. The data governance service is configured to receive the event from the event collection interface and to process the event to determine whether the file system operation conflicts with a governance policy of the data governance system. The enforcement service executes a set of remediation actions if the file system operation does conflict with the governance policy.

    摘要： 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.

    摘要： 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.
