  • Patent number: 10324807
    Abstract: Native file system creation for backup files is described. A system creates a virtual disk template corresponding to a disk associated with a client device. The system sends a copy of the virtual disk template as template data. The system sends a copy of a file on the disk as file data. The system stores a backup file in a file system format that is native to the client device by combining the template data and the file data. The system restores a file in the backup file to the disk via mounting the backup file as a virtual disk on the client device.

  • Patent number: 10108647
    Abstract: According to one embodiment, a restore module of a storage system receives a request from a client device over a network for restoring a data stream stored in the storage system. In response to the request, the restore module identifies a sparse disk file stored in the storage system, where the sparse disk file represents the requested data stream. The sparse disk file includes payload blocks sparsely located and intertwined with metadata of the sparse disk file. A converter executed in a memory by a processor of the storage system converts the sparse disk file into a native disk file based on the payload blocks of the sparse disk file, using a fast-copy method without having physically copying data content of the payload blocks. A block-based accessing interface is provided to the client to allow the client accessing the native disk file. Each block of content represented by the native disk is accessed based on a block identifier and an offset indicating a location of the block within the native disk file.

  • Patent number: 9971797
    Abstract: According to one embodiment, analytics module of a storage system receives a request for analyzing a data stream stored in the storage system. In response to the request, the analytics module identifies a sparse disk file stored in the storage system representing the requested data stream. The sparse disk file includes payload blocks sparsely located and intertwined with metadata of the sparse disk file. A converter converts the sparse disk file into multiple native disk files based on the payload blocks of the sparse disk file, using a fast-copy method without having physically copying data content of the payload blocks. A block-based accessing interface is provided to allow multiple clients to concurrently access the native disk files, respectively. Each block of content represented by the native disk is accessed based on a block identifier and an offset indicating a location of the block within the native disk file.

  • Patent number: 9690501
    Abstract: Techniques for determining characteristics of data blocks being accessed in a storage system are described herein. According to one embodiment, an input/output (IO) request is received for accessing a first data block of a first file stored in a storage system. The first file is one of the files stored in the storage system and each file contains multiple data blocks. In response to the request, a block-based monitor executed in a memory by a processor accesses a set of monitoring rules to determine whether the first file should be monitored. If so, the block-based monitor captures statistics data associated with the first data block and stores the statistics data of the first data block in a statistics database maintained in a persistent storage device. The statistics database stores statistics data of the data blocks of files monitored and captured based on the set of monitoring rules.
