Abstract: A protection application detects and remediates malicious files on a client. The protection application trains models using known samples of static clean files, and the models characterize features of the clean files. A model may be selected based on metadata obtained from a target file. By processing features of the clean files and features of the target file, the model may generate an anomaly score indicating a level of dissimilarity between the target file and the sample. The protection application compares the anomaly score to one or more threshold scores to classify the target file. Additionally, the target file may be provided to a security server to check against a whitelist or blacklist for classification. Responsive to a classification as malicious, the protection application remediates the target file on the client.

Abstract: The present disclosure provides for defragmenting deduplicated data, such as one or more backup image files, stored in a deduplicated data store. A defragmentation module can be implemented on a deduplication server to reduce fragmentation of backup images and improve processing time for restoring a backup image. A defragmentation module can be configured to defragment a backup image file by migrating portions of data of the backup image file that are stored in various containers at non-contiguous locations throughout deduplicated data store. A defragmentation module can contiguously write the portions to one or more containers, which are stored at one or more new locations in the deduplicated data store. A defragmentation module can be configured to evaluate whether portions of a backup image file meet criteria for defragmentation. A defragmentation module can also be configured to update location information about the portions that are migrated to the new container(s).

Abstract: A system and method for caching fingerprints in a client cache is provided. A data object that comprises a set of data segments and describes a backup process is identified. Thereafter, a request referencing the data object is made to a deduplication server to request that a task identifier be added to the data object. If the deduplication server is able to successfully add the task identifier to the data object, then an active identifier is added to each data segment from the set of data segments in a cache that is within a client system.

Abstract: Method and apparatus for allocating resources among backup tasks in a data backup system is described. One aspect of the invention relates to managing backup tasks in a computer network. An estimated resource utilization is established for each of the backup tasks based on a set of backup statistics. A resource reservation is allocated for each of the backup tasks based on the estimated resource utilization thereof. The resource reservation of each of the backup tasks is dynamically changed during performance thereof.

Abstract: Methods, systems, and computer program products for substitution of card-based telephony bearer channel switch modules in a manner that preserves stable calls are disclosed. According to one method, a first card-based telephony bearer channel switch module of a plurality of card-based telephony bearer channel switch modules is designated as a substitution switch module. A second card-based telephony bearer channel switch module of the plurality of card-based telephony bearer channel switch module is designated as an active switch module. Stable calls are established using the second card-based telephony bearer channel switch module. Configuration information for the second card-based telephony bearer channel switch module is communicated to the first card-based telephony bearer channel switch module. Call state information for calls involving the second card-based telephony bearer channel switch module is obtained from the first card-based telephony bearer channel switch modules.

Abstract: In one embodiment, the invention is directed to methods and system for converting an analog signal to digital samples for transmission over a communication network, and for converting digital samples received over a communication network to an analog signal. According to one feature, the system of the invention generates encoding and decoding master clocks from local oscillators, thus enabling the system of the invention to operate in environments where reliable timing signal are not available from the communication network. According to another feature, the system of the invention adjusts the frequencies of the encoding and decoding master clocks based on a connect rate to the communication network.

Abstract: A sterile specimen cup with a self-sealing membrane in the top that allows fluids to be injected into or with drawn from the cup with a syringe. This allows the specimen cup to be fully operated with one hand without removing the cover, thus increasing user safety, and sterility.
