Abstract: A technique improves storage efficiency of an object store configured to maintain numerous snapshots for long-term storage in an archival storage system by efficiently determining data that is exclusively owned by an expiring snapshot to allow deletion of the expiring snapshot from the object store. The technique involves managing index data structures to enable efficient garbage collection across a very large number of data objects. When a snapshot expires, the technique obviates the need to scan the numerous snapshot data objects to determine which index structures are no longer needed and can be reclaimed (garbage collected). The technique is directed to management of underlying storage based on different sets of policies. When certain snapshots expire and are ready for deletion, the technique is directed to finding those data blocks that are no longer referenced (used) by any valid snapshots.

Abstract: There is disclosed in one example a method of detecting computer malware, including: receiving a binary object for analysis; allocating the binary object to a sandbox; within the sandbox, loading the binary object into an executable memory region; performing a memory dump of the executable memory region; and analyzing the memory dump for malware characteristics.

Abstract: A reference snapshot selection technique is configured to select a reference snapshot resolution algorithm used to determine an appropriate reference snapshot that may be employed to perform incremental snapshot replication of workload data between primary and secondary sites in a data replication environment. A reference resolution procedure is configured to process a set of constraints from the data replication environment to dynamically select the reference snapshot resolution algorithm based on a figure of merit that satisfies administrative constraints to reduce or optimize resource utilization in the data replication environment.

Abstract: Provided herein are Complement Factor I (CFI) variants that exhibit at least one improved characteristic relative to a wild type CFI. CFI variants of the disclosure can exhibit tunable specificity and activity. Also included are CFI-containing fusion constructs comprising at least one domain of CFI, for example, wild type full length CFI fused to human serum albumin. Also included are methods of making and using such CFI variants and fusion constructs. The CFI variants and fusion constructs provided herein may be useful for treating a disease or condition associated with dysregulation of the complement system or a deficiency of CFI.

Abstract: An indexing technique provides an index data structure for efficient retrieval of a snapshot from a long-term storage service (LTSS) of an archival storage system. The snapshot is generated from typed data of a logical entity, such as a virtual disk (vdisk). The data of the snapshot is replicated to a frontend data service of the LTSS sequentially and organized as one or more data objects for storage by a backend data service of LTSS in an object store of the archival storage system. Metadata associated with the snapshot (i.e., snapshot metadata) is recorded as a log and persistently stored on storage media local to the frontend data service. The snapshot metadata includes information describing the snapshot data, e.g., a logical offset range of a snapshot of the vdisk and, thus, is used to construct the index data structure. Notably, construction of the index data structure is deferred until after the entirety of the snapshot data has been replicated and received by the frontend data service.

Abstract: In a second group of embodiments, an electronic device that provides a virtual Bluetooth gateway is described. During operation, the electronic device may receive a first packet associated with a second electronic device and that has an Internet Protocol (IP)-compatible format (such as a JavaScript Object Notation or JSON format). Then, the electronic device may de-encapsulate a second packet from the first packet, where the second packet is compatible with a Bluetooth communication protocol. Next, the electronic may provide the second packet. Note that the electronic device may not include a physical Bluetooth radio, such as dedicated hardware for a physical Bluetooth radio. Instead, the electronic device may include a virtual Bluetooth device that communicates with the second electronic device via the virtual Bluetooth gateway. This virtual Bluetooth device may have the capabilities of a physical Bluetooth radio (without the dedicated hardware).

Abstract: Methods, systems and computer program products for high-availability computing. In a computing configuration comprising a primary node, a first backup node, and a second backup node, a particular data state is restored to the primary node from a backup snapshot at the second backup node. Firstly, a snapshot coverage gap is identified between a primary node snapshot at the primary node and the backup snapshot at the second backup node. Next, intervening snapshots at the first backup node that fills the snapshot coverage gap are identified and located. Having both the backup snapshot from the second backup node and the intervening snapshots from the first backup node, the particular data state at the primary node is restored by performing differencing operations between the primary node snapshot, the backup snapshot from the second backup node, and the intervening snapshots of the first backup node.
