摘要： A method of limiting redundant storage of data comprises receiving a data stream and partitioning the data stream into a series of data chunks. At least one content hash value for a set of data chunks is generated based on data content of the set of data chunks. One or more data chunks are grouped into a segment with at least one boundary of the segment defined based on an evaluation of content hash values of data chunks. Content hash values of data chunks of the segment are compared to content hash values of data chunks of segments stored on a backup mass storage device. A pointer to a stored data chunk of an existing segment is stored on the backup mass storage device if a content hash value of a data chunk of the segment matches the content hash value of the stored data chunk.
摘要翻译：限制数据的冗余存储的方法包括接收数据流并将数据流划分成一系列数据块。基于该组数据块的数据内容生成用于一组数据块的至少一个内容哈希值。一个或多个数据块被分组成具有基于对数据块的内容哈希值的评估定义的段的至少一个边界的段。将段的数据块的内容哈希值与存储在备份大容量存储设备上的段的数据块的内容哈希值进行比较。如果段的数据块的内容散列值与存储的数据块的内容哈希值匹配，则指向现有段的存储数据块的指针被存储在备份大容量存储设备上。

摘要： Data objects are selectively stored across a plurality of differential data stores, where selection of the differential data stores for storing respective data objects is according to a criterion relating to compression of the data objects in each of the data stores, and where the differential data stores are stored in persistent storage media. Plural requests for accessing the differential data stores are batched, and one of the differential data stores is selected to page into temporary storage from the persistent storage media. The batched plural requests for accessing the selected differential data store that has been paged into the temporary storage are executed.

摘要： A plurality of differential data stores are stored in persistent storage media. In response to receiving a first request to store a particular data object, one of the differential data stores that are stored in the persistent storage media is selected, wherein selecting the one differential data store is according to a criterion relating to compression of data objects in the differential data stores. The selected differential data store is copied into temporary storage media, where the copying is not delayed after receiving the first request to await receipt of more requests. The particular data object is inserted into the copy of the selected differential data store in the temporary storage media, where the inserting is performed without having to retrieve more data from the selected differential store in the persistent storage media. The selected differential data store in the persistent storage media is replaced with the copy of the selected differential data store in the temporary storage media that has been modified.

摘要： Provided are, among other things, systems, methods and techniques for determining applicability of a policy defined by reference to a source document. A first sketch that was generated based on content of the source document is obtained, and a matching criterion is defined based on the first sketch. Also obtained is a second sketch that was generated based on content of a potential target document. A determination is made as to whether the policy applies to the potential target document based on whether the second sketch satisfies the matching criterion and, if the policy applies, a notification regarding applicability of the policy automatically is provided and/or an action automatically is blocked so as to prevent a violation of the policy.
