    Abstract: A network-based data store maintaining storage volumes for file systems at storage clients may implement dynamic storage volume scaling. A scaling event may be detected according to a specified scaling policy for a storage volume maintained at a network-based data store that is mounted at a storage client and configured for a file system. In a least some embodiments, the scaling policy for the storage volume may be received from the storage client. In response to detecting the storage event, storage maintaining the storage volume may be modified according to the scaling policy to scale the storage volume. An indication of the scaling event may be sent to the storage client in order to update the file system at the storage client so that the file system may utilize the scaled storage volume.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing data are disclosed. In some implementations, visual representations of files are generated for presentation in a backup user interface. The visual representations are generated from sparse file system metadata stored on the computing device, thus allowing faster navigating of the backup user interface. During a restore operation, the metadata can be used to retrieve the items from their physical storage locations. In some implementations, when the storage capacity of a backup storage device exceeds a threshold, the data for the N oldest backups are replaced with sparse file system metadata, which can be used to generate visual representations for presentation in the backup user interface.

    Abstract: A key-value store provides column-oriented access to data in a distributed and fault tolerant manner. Data can be inserted into the data store and data can be retrieved either randomly or sequentially from the data store at high rates. Keys for a table are ordered and the entire table is divided into key ranges. Each key range is handled by a table which itself is divided into key ranges called a partition. Partitions are also divided into segments. Such recursive division into smaller and smaller key ranges provides parallelism. At the highest level, operations on tablets can be distributed to different nodes. At lower levels, different threads can handle operations on individual segments. Large-scale restructuring operations can be decomposed into operations on individual segments so that a global lock on larger objects does not need to be kept across the entire operation.

    Abstract translation: 键值存储以分布式和容错方式提供对列数据的访问。 数据可以插入到数据存储中,数据可以从数据存储中以高速率随机或顺序检索。 表的键被排序,整个表被分成键范围。 每个密钥范围都由一个表格来处理,该表格本身被划分为称为分区的密钥范围。 分区也被分成多个部分。 这种递归的划分成越来越小的密钥范围提供了并行性。 在最高级别上,平板电脑上的操作可以分配到不同的节点。 在较低的级别,不同的线程可以处理各个细分市场的操作。 大规模的重组操作可以分解为各个部分的操作,从而不需要在整个操作中保持对较大对象的全局锁定。

    Abstract: Methods for generating file relationship data, and media file systems that generate file relationship data A method of generating, in a media file system comprising a data store and a file record database, file relationship data for a first media file in the media file system. The method determines the essence data in the data store from which the first media file was derived, by determining from the file record for the media file in the file record database details of any previous media files in the media file system from which the media file was created. If the media file was not created from any previous media files, the essence data in the data store that constitutes the media file is determined from the file record. If on the other hand the media file was created from any previous media files, the previous steps are repeated for the previous media files. The file relationship data is the generated using the details of the determined essence data.
