摘要： 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.

摘要： Systems and methods for simplifying and consolidating permission sets from multiple heterogeneous file storage systems are disclosed. An example method includes acquiring from the first file storage system a first set of file system permissions having a first set of permission semantics, and acquiring from a second file storage system a second set of file system permissions having a second set of permission semantics that are different from the first set of permission semantics. The first set of file system permissions and the second set of file system permissions are converted to a unified set of file system permissions having unified permission semantics that are different from the first set of permission semantics and the second set of permission semantics. The unified set of file system permissions can be analyzed to make a determination regarding security levels of the first file storage system and of the second file storage system.

摘要： A system for facilitating upload file optimization via transaction transformation. A request is received for an operation to upload a file to the cloud. The system bypasses a transaction processing (sub)system and attempts to upload the file to a staging area of the cloud. When the upload transaction is ready to be executed, the system determines an upload status of the file. The system transfers the file from the staging area to an intended destination if the file has been uploaded to the staging area. If the file is not yet uploaded to the staging area, the system determines if an upload operation failed. If an upload operation did not fail, the system waits for the upload to finish prior to transferring the file to the intended destination. If the upload operation did fail, the system uploads the file to the intended destination.

摘要： A method for providing access to objects associated with a particular client in a cloud storage system is disclosed. The method includes the steps of establishing a connection with a user, providing a client namespace associated with the client to the user, where the client namespace represents objects stored on the cloud storage system and objects stored on a private storage system apart from the cloud storage system, receiving a request from the user to access an object stored on the private storage system, and providing information to the user to facilitate access to the object stored on the private storage system by said user. Other systems and methods are also disclosed. Important advantages of the present invention are facilitated by separating the logic for user access (control plane) from the actual storage (Storage plane). Private file system access can still be managed from the cloud, while keeping the client data private.

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 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： 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.

摘要： A system for effectively addressing the fast-producer and slow-consumer problem for persistent hybrid cloud caches. In particular, the system and associated methods ensure the integrity of data stored by persistent caches by utilizing a plurality of journals, including a user journal and a cloud journal. The user journal records operations conducted by users of the system in records. Before the records are transferred to a cloud storage system, the records are transferred to the cloud journal, which may he configured to he larger than the user journal. Once a record is transferred from the user journal to the cloud journal, the record may be released from the user journal, thereby increasing capacity of the user journal for subsequent operations to be recorded. Each record may then be transferred to the cloud storage system from the cloud journal, which may then cause each record to be released from the cloud journal.

摘要： Example systems and methods for efficient data governance are disclosed. Metadata associated with file objects is analyzed to estimate, for each file object, likelihood that the file object includes sensitive data. The estimates are used to prioritize the file objects for analysis of the file objects’ content to determine the objects include data deemed to be of a sensitive nature. In cloud-based systems/methods the estimates are also used to prioritize the file objects for transfer from a remote file storage system to the cloud-based system for analysis of content. The disclosed systems and methods significantly reduce the time required to identify sensitive file content in a large number of file objects.
