For example, an instance of a computer application may be executed at a first electronic device and a backup event that occurs in the first electronic device may be determined. The backup event may suggest a backup of application state data and the application state data may represent an application state of the computer application at the backup event. The application state data of the computer application is transmitted to a remote storage service in response to the backup event. A second electronic device can retrieve the application state data from the remote storage service and restore the application state.

The computing device identifies some of the storage objects that have a high possibility to be read by computer applications of the computing device, and caches the content data of these storage objects locally.

Abstract: Some examples include decomposing an application into fragments and streaming the application in fragments. For instance, a plurality of application fragments may include a first application fragment and a second application fragment that each correspond to a portion of a mobile game application. When streaming the first application fragment to the mobile device, a system may determine that the second application fragment follows the first application fragment based on a fragments relationship data structure. The fragments relationship data structure may associate the first application fragment with the second application fragment based on an analysis of the fragment information that indicates that the second application fragment follows the first application fragment during operation of the mobile game application. The system may stream the second application fragment to the mobile device based on the determination that the second application fragment follows the first application fragment.

The server may identify, for each of the data files, the one or more data backup policies with which the corresponding data file matches and a corresponding set of the multiple computing devices associated with the one or more of the data backup policies. Further, the server may transmit each of the data files to the corresponding set of computing devices.

For instance, the application, associated application data, and/or saved application state information may be deleted from the electronic device. Subsequently, an application launcher may present a launcher user interface (UI) on a display associated with the electronic device. The launcher UI may include a first set of application representations corresponding to applications offloaded from the electronic device, and a second set of application representations corresponding to applications currently installed on the electronic device. In response to receiving a selection of one of the representations from the first set via the launcher UI, the selected application may be onloaded onto the electronic device. Further, in some cases, the electronic device may receive from the network storage at least one of the application data or the application state information for the onloaded application.

Abstract: Technology is disclosed for backing up and retrieving data in a distributed backup system (“the technology”). Files of a user can be stored across multiple computing devices (“the devices”) of the user, e.g., mobile devices, and/or at a server, e.g., a cloud storage server, in the distributed backup system. The user can define various policies for storing different files at different devices. For example, the user may define a policy for storing video files on a device that has a bigger display. The devices can be used as an edge cache of the distributed backup system in serving files to the user. Upon receiving a request for retrieving a file, the technology determines if any of the user devices that are in proximity to the requesting device has the file. If yes, the file is transmitted to the user from the proximate device instead of from the server.

A second electronic device may retrieve the application state data from the remote storage service and restore the game application state.

The neighbor computing device maintains a network connection with the storage server. The storage server transmits a second data set relevant to the first data set to the neighbor computing device. In response to a read request for the second data set from the computing device, the storage server sends to the computing device an instruction indicating that the neighbor computing device is storing a data cache for the computing device.

Gaming data file access patterns on the electronic devices are analyzed, individually and collectively, using a cloud service to detect global access patterns and help determine which gaming data files to preload on each of the electronic devices.

Abstract: An electronic device may offload an application to a network storage to free up storage on the electronic device. For instance, an application file and, in some cases, associated application data and/or saved application state information may be stored at the network storage and deleted from the electronic device. Subsequently, a data management module may receive an instruction to onload the application back onto the electronic device, such as in response to a user input that selects the offloaded application, a determination that an upcoming activity may include use of the offloaded application, or a determination that a user usage pattern indicates that the offloaded application is likely to be used. In response, the data management module may download the corresponding application file from the network storage. In some cases, the electronic device may also receive associated application data and/or saved application state information from the network storage.

Abstract: Technology is disclosed herein for sharing encrypted data within a client-server distributed data storage system. According to at least one embodiment, a first computing device encrypts multiple data sets of the first computing device using symmetric encryption keys. Each of the data sets is encrypted using a different symmetric encryption key among the symmetric encryption keys. The first computing device shares the encrypted data sets with a second computing device. The first computing device further sends the symmetric encryption keys to the second computing device via a secured channel. The symmetric encryption keys are suitable for decrypting the encrypted data sets at the second computing device. The secured channel is through a server connected with the first and second computing devices. The server cannot access the contents of the secured channel and cannot access contents of the encrypted data sets.
