Abstract: Embodiments manage data transfer requests representing backup operations and update operations from a computing device using a centralized data transfer service. The data transfer service selects the data transfer requests for performance based at least on data usage statistics associated with a data usage plan and available network connections on the computing device. For the backup operations, the data transfer requests are also selected based on priority information associated with each of the backup operations. In some embodiments, the data transfer service selects and initiates the data transfer requests without incurring excess data transfer costs for the user.

Abstract: A pluggable file-based DRM (digital rights management) API (application program interface) layer for applications and engines. The invention defines a pluggable file-based DRM API layer such that mobile operators can choose to use any file-based DRM (FDRM) engine in their final product. An FDRM engine can be content agnostic (e.g., can range from an executable to a media file or ring-tone). In accordance with the invention, an application can become DRM aware by calling the novel file-based DRM APIs. Any FDRM engine can be plugged into the novel API layer such that applications can use the protected content. The API layer of the subject invention can be designed such that applications that are DRM aware by using the file-based DRM API layer can be DRM engine agnostic.
