Abstract: A technique includes receiving a request to restore a state of a file system. The request defines a rollback period, which extends from a restoration time that is specified by the request to a time at which the request was made. The technique includes reconstructing a state of the file system in response to a query using a preserved snapshot of the file system. The reconstruction including reconstructing the state at an arbitrary query time based at least in part on a dynamically inheritable attribute of an entity stored on the file system and the rollback period.

Abstract translation: 一种技术包括接收恢复文件系统的状态的请求。 该请求定义了从请求指定的恢复时间到请求时间的回滚周期。 该技术包括使用文件系统的保留快照来响应于查询重建文件系统的状态。 该重建包括至少部分地基于存储在文件系统上的实体的动态可继承属性和回滚周期在任意查询时间重建状态。

Abstract: A technique includes receiving a query to a directory in a file system. In response to the query, both information targeted by the query and additional information are retrieved in anticipation of another query for the additional information.

Abstract translation: 一种技术包括接收到文件系统中的目录的查询。 响应于该查询，查询查询的两个信息和附加信息被检索以预期另一查询的附加信息。

Abstract: A storage system includes a distributed file system. An attribute of a particular entity in the file system relates to a snapshot. In response to an operation in the storage system, it is determined whether the snapshot attribute is to be propagated to another entity of the file system.

Abstract translation: 存储系统包括分布式文件系统。 文件系统中特定实体的属性与快照有关。 响应于存储系统中的操作，确定快照属性是否被传播到文件系统的另一个实体。
