Methods and systems for file locking are described herein. An on-premise file share may store files that are accessible to both a local on-premise client and a remote off-premise client. The off-premise file share may request to check-out one of the files. In response, one of multiple nodes may obtain for the file a file handle with exclusive write access. File locking information may be stored at the file share that indicates the node that holds the file handle and that indicates the file is in a locked state whereby other remote off-premise clients or local on-premise clients are prevented from editing the file.

A highly secure file system stores and accesses files utilizing familiar hierarchical concepts for file storage (i.e. root directory, directory, file entry data, etc.), while at the same time hiding the actual path to access the desired file. A file may be stored and accessed at a data store node using a Uniform Resource Identifier (URI) path comprising a unique, unidirectional relationship identifier that controls a requesting entity's access to the file system. The URI path may also comprise a “leaf” unique uniform identifier (UUID) derived from linkages between the hierarchical nodes superordinate to the data store node.

Name caching can be used external to a distributed file system (DFS), such as a network file system (NFS), to reduce the complexity of facilitating a file operation at the DFS. A system that can use the name caching and request the file operation of the DFS can comprise a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can comprise, in response to a lookup operation or a file operation performed by a DFS, storing, using the processor, a name cache entry for each directory element accessed during the lookup operation or the file operation. The operations further can comprise sending, to the DFS, a single request that comprises a compound command comprising requests for a set of lookup operations and for a file operation.

The present technology pertains to a organization directory hosted by a synchronized content management system. The corporate directory can provide access to user accounts for all members of the organization to all content items in the organization directory on the respective file systems of the members' client devices. Members can reach any content item at the same path as other members relative to the organization directory root on their respective client device. In some embodiments novel access permissions are granted to maintain path consistency.

Techniques are provided for persistent memory file system reconciliation. As part of the persistent memory file system reconciliation, high level file system metadata associated with a persistent memory file system of persistent memory is reconciled. Client access to the persistent memory file system is inaccessible until reconciliation of the high level file system metadata has completed. A first scanner is executed to traverse pages of the persistent memory in order to fix local inconsistencies associated with the pages. A local inconsistency of a first set of metadata or data of a page is fixed using a second set of metadata or data of the page. The first scanner is executed asynchronously in parallel with processing client I/O directed to the persistent memory file system.

In an approach for classifying and storing multiple layers of a file system as platform-dependent and platform-independent layers, a processor generates an initial layer of a file system. The initial layer is a platform-dependent base layer. A processor assigns one or more files associated with the initial layer with a first group identification as a first same group in a file registry for a plurality of platforms. A processor generates a new layer based on the initial layer into the file system. A processor, in response to the new layer being platform-independent, marks the new layer as platform-independent in the file registry. A processor pushes the new layer into the file registry for one of the plurality of platforms. A processor distributes one or more corresponding files from the file registry per a client request to access the file system.

A server in a cloud-based environment interfaces with storage devices that store shared content accessible by two or more users. Individual items within the shared content are associated with respective object metadata that is also stored in the cloud-based environment. Download requests initiate downloads of instances of a virtual file system module to two or more user devices associated with two or more users. The downloaded virtual file system modules capture local metadata that pertains to local object operations directed by the users over the shared content. Changed object metadata attributes are delivered to the server and to other user devices that are accessing the shared content. Peer-to-peer connections can be established between the two or more user devices. Object can be divided into smaller portions such that processing the individual smaller portions of a larger object reduces the likelihood of a conflict between user operations over the shared content.

A computing system may include a proxy server application and a database. The proxy server application may provide, to a computing device disposed within a managed network, instructions to identify one or more processes executing on the computing device. The proxy server application may also determine, for a process of the one or more processes, a file system path of a directory associated with the process and, based thereon, select one or more directories to scan for files associated with the process. The computing device may be provided with instructions to (i) scan the one or more directories and (ii) determine a plurality of attributes associated with one or more files discovered therein. The proxy server application may additionally receive results of the scan containing a representation of the plurality of attributes and store, in the database, the results of the scan.

A system and method for storing data in a distributed network having a plurality of datacenters distributed over a plurality of geographic regions. The method may involve receiving data, including metadata, uploaded to a first datacenter of the distributed network, receiving access information about previous data that was previously stored in the plurality of datacenters of the distributed network, predicting one or more of the plurality of geographic regions from which the uploaded data will be accessed based on the metadata and the access information, and instructing the uploaded data to be transferred from the first datacenter to one or more second datacenters located at each of the one or more predicted geographic regions.

Systems and methods for replacing original media bookmarks of at least a portion of a digital media file with replacement bookmarks is described. A media fingerprint engine detects the location of the original fingerprints associated with the portion of the digital media file and a region analysis algorithm characterizes regions of media file spanning the location of the original bookmarks by data class types. The replacement bookmarks are associated with the data class types and are overwritten or otherwise are substituted for the original bookmarks. The replacement bookmarks then are subjected to a fingerprint matching algorithm that incorporates media timeline and media related metadata.
