A storage server communicating with a backend storage provider, such as a cloud-based provider, performs processes for backing up encrypted data in the backend storage in a data cache shared by multiple decentralized applications, to allow a user of a frontend client to revert to a prior version of an encrypted file if that encrypted file has been compromised by one of the decentralized applications, where the storage server performs no encryption of the data and is not exposed to encryption keys.

Operations and Maintenance Design drawing maintenance, As-Built drawing conformance, and Record drawing conformance processes for protecting the integrity of dynamically modified files through all phases of a drawing's lifecycle.

A non-transitory computer-readable storage medium having stored therein a program executing a process includes when starting capture of data, acquiring a pair of first identification information and a file name; recording the pair and an acquisition time in management information; when it is detected that the first identification information included in the captured data is associated with a file name included in another data captured before the captured data, recording a pair of the first identification information and the file name and a capture time in the management information; when a reference request for the data is received, specifying a file name corresponding to first identification information and time information included in the reference request, the file name being specified by referring to the management information; converting the first identification information into the specified file name, the first identification information being included in the data; and outputting the data.

A computer-implemented method according to one embodiment includes, in response to a determination that a predetermined operation has been performed on an object of a first file stored on a first cluster site, storing predetermined information about the object of the first file stored on the first cluster site. The predetermined information is stored on an extended attribute of the first file stored on the first cluster site. In response to a determination that the predetermined operation is performed on an object of a first file stored on a second cluster site, the predetermined information is removed from the extended attribute of the first file stored on the first cluster site. In response to a determination that a failure event has occurred on a queue of the first cluster site, a predetermined recovery process is performed, thereby enabling fulfillment of entries of the queue of the first cluster site.

There is provided a file management device includes: a memory; and a processor coupled to the memory and the processor configured to determine a naming rule for a file name to be assigned to an electronic file for a document, based on a format of the document; and determine the file name by using a character string included in the electronic file in accordance with the determined naming rule. The processor is further configured to store, with respect to an existing electronic file, naming rules relating to documents having a common format, in association with the format; and select, for an electronic file for a newly input document, a naming rule to be applied, from among the stored naming rules, based on a format of the electronic file.

ID management for a network attached storage system using layered ID mapping virtualization. When a connection request is received at a NAS server, it is determined whether the request is for a new user, and if so, user IDs are created for the new user. External user ID and filesystem user ID are mapped to the internal user ID, and user ID is verified at the NAS server kernel on subsequent logins with an external database. The user IDs are remapped for the changed user account, and updated mappings are transmitted from the NAS server to one or more NAS server kernel repositories.

A caseless file lookup in a distributed file system is disclosed. A request to store a file in a volume may be received. In response to the request, the type of client system issuing the request may be identified. Based on the type of client system that has been identified, a first hash value or a second hash value may be calculated for the name of the file to generate and assign a hash value to the file. The file may be stored in a storage resource based on the first or second hash value that has been generated for the file.

A system and method for interactive visual representation of metadata within a networked heterogeneous workflow environment is disclosed. In one embodiment of the system, a document management server is configured to provide an enterprise environment having storage, versioning, metadata, security, indexing, and retrieval of a multitude of files having various users. Geolocation metadata includes information used to identify a subject physical location relevant to each file. Geolocation data includes information used to identify a physical location of a geo-location computing device in communication with the document management system. The document management server generates predictive geo-relevant metadata by evaluating the geolocation metadata associated with the files and the geolocation data received from the geolocation-enabled computing device.

Systems and methods for reducing locks on a storage layout of a distributed file system by detecting and notifying clients of stale storage layouts. An example method may comprise: receiving a request to modify a file system object associated with a storage layout, the request comprising an index range and the storage layout comprising an index range; determining whether the request is associated with a stale storage layout in view of a comparison of the index range of the request and the one or more index ranges of the storage layout; receiving a lock request to prevent changes to the storage layout; and transmitting at least a portion of the storage layout to update the stale storage layout.

The present disclosure relates to systems, methods, and non-transitory computer readable media for clustering media items in a semantic space to generate theme-based folders that organize media items by content theme. In particular, the disclosed systems can access media items that are stored in an original folder structure. The disclosed systems can generate content-based tags for each media item in a collection of media items. Based on the generated tags, the disclosed systems can map the collection of media items to a semantic space and cluster the collection of media items. The disclosed systems determine themes for the clusters based on the generated tags. The disclosed systems can present a media item navigation graphical user interface comprising the collection of media items organized by themes. The disclosed system can present the media item navigation graphical user interface without altering the original folder structure.
