  • Patent number: 11048417
    Abstract: Techniques perform storage management. Such techniques involve: detecting a change of a size of storage space for a file system, the file system having one or more associated bitmaps, each active bit in the one or more bitmaps indicating data status in storage space not exceeding an upper size limit of the file system; in response to detecting the change, determining, based on the upper size limit, a first number of bits required for indicating the changed storage space; and in response to determining that the first number exceeds a second number of current active bits in the one or more bitmaps, allocating at least one additional active bit for the file system. Accordingly, the number of bits for indicating the file system can be dynamically adjusted based on the changes of the file system.

  • Publication number: 20210133045
    Abstract: Techniques for backing up data involve receiving, by a proxy server and from an application, a backup request comprising a backup path. The techniques further involve determining a target server associated with backup request according to the backup path, and the proxy server and the target server share the same storage processor. The techniques further involve backing up a file in the target server associated with the backup path. Along these lines, a dedicated proxy server may be provided, and the proxy server may be used to handle backup requests for all file systems on the storage processor. Then, the backup requests can be forwarded to the corresponding target servers through a virtual file system without configuring corresponding Internet protocol (IP) address for each target server.

  • Publication number: 20210034570
    Abstract: Techniques manage snapshots in an application environment. The application environment includes a first application system and a second application system. A group of snapshots of the first application system are identified in a fracture state where synchronous communication between the first application system and the second application system is paused. A group of snapshot differences between two successive snapshots in the group of snapshots are obtained, the group of snapshots being arranged in chronological order that the group of snapshots are generated. The group of snapshot differences are transmitted from the first application system to the second application system in response to determining the synchronous communication between the first application system and the second application system is resumed.

  • Patent number: 10853209
    Abstract: Techniques for data synchronization involve obtaining a first bitmap about a first storage device, the first storage device including a group of storage areas, a bit in the first bitmap indicating whether data in a corresponding storage area of a first size in the group of storage areas is to be synchronized to a second storage device. The technique further involves, in response to a configuration of the first storage device being changed, determining a second size of a storage area in the group of storage areas. The technique further involves converting the first bitmap into a second bitmap based on the first size and the second size. In addition, the technique further involves synchronizing data from the first storage device to the second storage device based on the second size and the second bitmap.

  • Patent number: 10802923
    Abstract: Embodiments of the present disclosure relate to a method and apparatus for incremental backup. The method comprises receiving a set of file paths to be backed up and parsing each file path in the set of file paths to construct a prefix tree. The method further comprises traversing the prefix tree to read an ordered set of file paths in the prefix tree and performing an incremental backup sequentially according to the ordered set of file paths. Embodiments of the present disclosure sort a set of file paths to be backed up using a prefix tree that shares common path prefixes. Thus, embodiments of the present disclosure can achieve fast sort of the set of file paths, and can effectively save storage space needed for sorting a considerable number of file paths in the memory, thereby reducing the times of comparing file names when sorting file paths.

  • Publication number: 20200210553
    Abstract: This disclosure is directed to methods and systems for protecting a deep learning model from piracy and unauthorized uses. The protection may be implemented by embedding an ownership detection mechanism such that unauthorized use of the model may be detected using a detection input data and corresponding model signature. In addition, the deep learning model may be used in conjunction with a secret or license protected data encoder such that the deep learning model may generate meaningful output only when processing encoded input data. An unauthorized user who does not have access to the secret data encoder may not be able to use a pirated copy of the deep learning model to generate meaningful output. Under such a scheme, a deep learning model itself may be widely distributed without restriction and without license-protection.

  • Patent number: 10620826
    Abstract: A method includes receiving a user input (e.g., a one-touch user input), performing segmentation to generate multiple candidate regions of interest (ROIs) in response to the user input, and performing ROI fusion to generate a final ROI (e.g., for a computer vision application). In some cases, the segmentation may include motion-based segmentation, color-based segmentation, or a combination thereof. Further, in some cases, the ROI fusion may include intraframe (or spatial) ROI fusion, temporal ROI fusion, or a combination thereof.

  • Patent number: 10467142
    Abstract: This disclosure is directed to a system and a method for providing enhanced real-time or near-real-time response to request for detached data analytics services. In one implementation, a system is disclosed for predicting a data analytics service that may be requested by a user based on real-time user interactive operations, and for pre-loading/pre-configuring a pipeline of data analytics components for performing the predicted data analytics service before an actual request is made. Additionally, at least some intermediate data may be calculated by the pre-configured pipeline and may be pre-cached in memory. Upon actual user request for the data analytics service, only data analytics that require additional input data concurrently provided with the request would need to be performed. In such a manner, user-perceived delay in completing the detached data analytics service is reduced.
