Data recovery systems and methods utilize object-based storage for providing a data protection and recovery methodology with low recovery point objectives, and for enabling both full recovery and point-in-time based recovery. Data generated at a protected site (e.g., via one or more virtual machines) is intercepted during write procedures to primary storage. The intercepted data is replicated via a replication log, provided as data objects, and transmitted to an object based storage system. During recovery, data objects may be retrieved through point-in-time based recovery directly by the systems of the protected site, and/or data objects may be provided via full recovery, for example, within a runtime environment of a recovery site, with minimal data loss and operation interruption by rehydrating data objects within the runtime environment via low-latency data transfer and rehydration systems.

Time-based partitioning of a data set is applied to capture updates to the data set in a copy of the data set. Items that have been updated in a data set with in a time period are identified. Partitions of the data set that include the updated items are created according to a partitioning scheme. The created partitions are grouped in a storage location for the time period in a file structure that stores a copy of the database. A latest version of the copy of the data set may be accessed according to latest partitions of the data set stored in the different locations of the file structure.

A cloud computing system includes a cloud system managing unit, a plurality of sets of devices, where a set of devices includes one or more devices having a common aspect, and a plurality of authentication servers, where an authentication server is associated with one of the plurality of sets of devices based on the common aspect. The cloud computing system functions to establish trust between a corresponding one of the plurality of authentication servers and the one or more devices of one of the plurality of sets of devices, between the corresponding one of the plurality of authentication servers and the cloud system managing unit, and between the cloud system managing unit and the one or more devices. The cloud system managing unit configures the cloud computing system based on the trust between the cloud system managing unit and devices of the plurality of sets of devices.

User interface information related to relevant events of interest is provided. Events can occur anywhere in a document, and may or may not be relevant to a user utilizing an assistive technology (AT) application, such as a screen reader. A provider-side signaling system component determines whether raised events are relevant to the user. In some examples, when an application makes a plurality of attribute changes in a document at once, the signaling provider batches the related events as a single transaction, and generates a generalized annotation describing the changes. The signaling provider further packages the event notification, and sends the event notification to a client-side signaling system component. The signaling client receives the notification, and determines whether to alert the user of the event(s) based on verbosity settings. The AT application is enabled to interpret the event notification and alert the user in a meaningful way.

Provided herein are devices, systems, methods and various means, including those related to providing a community internet drive that may utilize a centrally-managed hub as well as storage devices distributed among various networked machines. In some embodiments, the community internet drive can also include features to enable its users to promote and utilize the user's trusted personal relationships while also enabling an open platform for peer-to-peer and/or other types of sharing schemes.

A server system, based on content of a first file stored on a first client device being modified, automatically receives a copy of the modified first file from a first transfer client, implemented on the first client device, the copy of the modified first file being an updated version of the first file generated from content of the first file being modified. The server system receives, from the first transfer client, first metadata associated with the updated version of the first file, the first metadata being assigned a first priority greater than a second priority assigned to the copy of the modified first file. The server system automatically transfers the first metadata to a second transfer client, implemented on a second client device, before the copy of the modified first file is transferred to the second transfer client to be stored on the second client device.

The present disclosure is directed toward systems and methods that efficiently and effectively generate and utilize collections of content items. For example, systems and methods described herein generate a collection content item including one or more content item references. In one or more embodiments, the collection content item can include content item references for content items located internally or externally, with granular levels of permissions settings and version controls. Additionally, in response to a detected selection of a content item reference, systems and methods described herein generate a rendering of the associated content item that can be viewed regardless of any third party software installed on the viewing client computing device.

Upon receiving a usage request that includes a file identifier and a version identifier from a user terminal 20, a control server 10 transmits a file request that is based on the usage request to a file management system, and transmits a permission information request that is based on the usage request to a distributed ledger system. Upon receiving the file request, the file management system acquires the file that corresponds to the combination of the file identifier and the version identifier and transmits the file to the control server 10. Upon receiving the permission information request, the distributed ledger system acquires permission information that corresponds to the combination of the file identifier and the version identifier from a distributed ledger, and transmits the permission information to the control server 10. The control server 10 transmits the file to the user terminal 20 if the user of the user terminal has viewing permission based on the permission information.

This invention discloses a novel system and method for comparing electronic documents that are created on different software platforms or that are in different data formats by traversing the two hierarchical representations of the documents in a manner so as to selectively ignore nodes in the hierarchy and attempt to resynchronize the sequence of traversing when nodes have no matching content.

Information source agent systems and methods for distributed content storage and management using content signatures that use file identicality properties are provided. A data management system is provided that includes a content engine for managing the storage of file content, a content signature generator that generates a unique content signature for a file processed by the content engine, a content signature comparator that compares content signatures and a content signature repository that stores content signatures. Information source agents are provided that include content signature generators and content signature comparators. Methods are provided for the efficient management of files using content signatures that take advantage of file identicality properties. Content signature application modules and registries exist within information source clients and centralized servers to support the content signature methods.
