Abstract: Some embodiments provide, for a particular device in a set of related devices, a method for backing up data synchronized between the set of related devices. The method stores the backup data encrypted with a set of data encryption keys. The method also stores the set of data encryption keys encrypted with a master recovery key. The method also stores several copies of master recovery key data, each copy of the master recovery key data encrypted with a public key of a different one of the related devices. The backup data is only recoverable by accessing a private key of any one of the related devices.

Abstract: A method and an apparatus for determining a usage level of a memory device to notify a running application to perform memory reduction operations selected based on the memory usage level are described. An application calls APIs (Application Programming Interface) integrated with the application codes in the system to perform memory reduction operations. A memory usage level is determined according to a memory usage status received from the kernel of a system. A running application is associated with application priorities ranking multiple running applications statically or dynamically. Selecting memory reduction operations and notifying a running application are based on application priorities. Alternatively, a running application may determine a mode of operation to directly reduce memory usage in response to a notification for reducing memory usage without using API calls to other software.

Abstract: Some embodiments provide, for a particular device in a set of related devices, a method for backing up data synchronized between the devices. The method receives a command to create a backup for a subset of data synchronized between a subset of the devices, which is a subset of all data synchronized between the devices. The method identifies the subset of synchronization data from the set of all synchronization data. The subset of synchronization data is tagged as pertaining to a particular set of criteria for synchronization between only the subset of devices. The method stores a backup of the subset of synchronization data in a backup storage encrypted in such a way that requires a recovery key associated with any one of the devices in the subset of devices to access the backup while preventing access to the backup with recovery keys of any of the other devices.

Abstract: Systems, methods, and computer program products for target memory pressure event notifications are disclosed. Processes running on a device can register to receive memory pressure event notifications from a memory management system, which are sent while memory pages are being reclaimed. Active processes running on a device processor can be assigned a priority that ranges from low to high. Responsive to a memory pressure event occurring on the device, the memory management system determines whether less than a threshold number of high priority processes are active on the device. If so, the memory management system sends a memory pressure event notification to the registered process with the lowest priority among the active processes.
