Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for predicting a future context of a computing device. In some implementations, a context daemon can use historical context information to predict future events and/or context changes. For example, the context daemon can analyze historical context information to predict user sleep patterns, user exercise patterns, and/or other user activity. In some implementations, a context client can register a callback for a predicted future context. For example, the context client can request to be notified ten minutes in advance of a predicted event and/or context change. The context daemon can use the prediction to notify a context client in advance of the predicted event.

Abstract: A virtual storage appliance (VSA), acting as a target tape library emulating multiple tape drives. The overhead in processing the data within the VSA and the command blocks can be reduced by utilizing in-memory buffers as a pass-through to a storage media such as a target tape library. The VSA may function as a target device relative to a network server for use as a backup tape library. Furthermore, the VSA may include interface (which can be any interconnect interface like SCSI or FC) and buffers in the memory along with the command blocks which points to these buffers. The data that comes in from an initiator server is written onto a disk storage system. However, the same data buffers that are in the memory in the VSA can also be used to spool the data onto the tape library to eliminate further disk and file system overhead. The same in-memory buffer can now be used by the VSA that will act as an initiator to write to the target tape library.
