摘要: The subject disclosure is directed towards a data deduplication technology in which a hash index service's index maintains a hash index in a secondary storage device such as a hard drive, along with a compact index table and look-ahead cache in RAM that operate to reduce the I/O to access the secondary storage device during deduplication operations. Also described is a session cache for maintaining data during a deduplication session, and encoding of a read-only compact index table for efficiency.

摘要: A data feed is defined with a data type and criteria. Each data type corresponds to a type of management related data provided by a management system. The management system is searched for all management related data that corresponds with the data type and the criteria. An aggregator collects the management related data that corresponds with the data type and the criteria. The collected management related data is rendered for a display.

摘要: Aspects of the subject matter described herein relate to sharing volume data via shadow copies. In aspects, an active computer creates a shadow copy of a volume. The shadow copy is exposed to one or more passive computers that may read but not write to the volume. A passive computer may obtain data from the shadow copy by determining whether the data has been written to a differential area and, if so, reading it from the differential area. If the data has not been written to the differential area, the passive computer may obtain it by first reading it from the volume, then re-determining whether it has been written to the differential area, and if so, reading the data from the differential area. Otherwise, the data read from the volume corresponds to the data needed for the shadow copy.
摘要翻译: 本文描述的主题的方面涉及通过卷影副本共享卷数据。 在方面,活动计算机创建卷的卷影副本。 影子副本暴露给可能读取但不写入卷的一个或多个被动计算机。 无源计算机可以通过确定数据是否被写入差分区域而从影子拷贝获得数据,如果是,则从差分区域读取数据。 如果数据尚未写入差分区域,则无源计算机可以通过首先从卷中读取数据,然后重新确定是否将其写入差分区域,如果是,则从差分读取数据 区。 否则,从卷读取的数据对应于卷影副本所需的数据。
