摘要： A method for organizing a storage system that is scalable and fault tolerant, the method including grouping together a number D of storage elements to form the storage system, where D is more than one, constructing a storage assignment table that includes table entries, computing, for each of the storage elements, an available capacity that depends on constraints on the placement of redundant data within the storage system, summing the available capacities to form a total available capacity for the storage system; and assigning the table entries in the storage assignment table to each identify one of the storage elements, wherein the available capacity of each of the storage elements is its effective storage capacity when used as part of the storage system, wherein not all of the D storage elements that form the storage system have the same available capacity, and wherein the fraction of all table entries that identify a one of the storage elements depends upon its fraction of the total available capacity.

摘要： A method by which a disk-based distributed data storage system is organized for protecting historical records of stored data entities. The method comprises recording distinct states of an entity, corresponding to different moments of time, as separate entity versions coexisting within the distributed data storage system, and assigning expiration times to the entity versions independently within each of a plurality of storage sites according to a shared set of rules, before which times deletion is prohibited.

摘要： A method for constructing an index suitable for indexing a large set of records identified by long generally randomly distributed record names and for answering membership queries about the set, the method comprising assigning each different record a different record name, determining that a new record name is not already represented in the index by checking an entry in a first level index that is shorter than the complete new record name, and determining that a queried record name is already represented in the index by determining that the queried record name is represented in a second level index that contains enough information to reconstruct the complete queried record name.

摘要： In general, the invention features methods by which more than one client program connected to a network stores the same data item on a storage device of a data repository connected to the network. In one aspect, the method comprises encrypting the data item using a key derived from the content of the data item, determining a digital fingerprint of the data item, and storing the data item on the storage device at a location or locations associated with the digital fingerprint. In a second aspect, the method comprises determining a digital fingerprint of the data item, testing for whether the data item is already stored in the repository by comparing the digital fingerprint of the data item to the digital fingerprints of data items already in storage in the repository, and challenging a client that is attempting to deposit a data item already stored in the repository, to ascertain that the client has the full data item.

摘要： A method for storing data items in a data repository that allows a client storing a data item to lose the ability to either retrieve the stored data item or enable its retrieval, while preserving controlled access to the stored data item indefinitely. The client storing the data item encrypts it using an encryption key that it creates, which may be derived from the content of the data item. The encryption key is also stored in the data repository in an encrypted form, with its encryption making use of a public key. The method allows storage space to be shared for identical data items encrypted and stored by independent clients of the data repository.
摘要翻译：一种在数据存储库中存储数据项的方法，其允许客户端存储数据项丢失检索所存储的数据项或启用其检索的能力，同时保持对存储的数据项的无限期的受控访问。存储数据项的客户端使用其创建的加密密钥对其进行加密，该加密密钥可以从数据项的内容导出。加密密钥也以加密形式存储在数据存储库中，其加密使用公钥。该方法允许为由数据存储库的独立客户端加密和存储的相同数据项共享存储空间。

摘要： In one aspect, in general, a method for managing data includes receiving, at a data deduplication engine of a computer system, data to be stored in a data storage system, computing a first value corresponding to at least one portion of the received data, determining that the first value matches a second value stored in a collection of identifiers, each identifier corresponding to a particular portion of data stored in the data storage system, each identifier comprising a computed value corresponding to the particular portion of data and including metadata indicating a location where the particular portion of data is being stored in the data storage system, and based on the determination that the first value matches a second value stored in the collection of identifiers, reallocating one or more physical locations from corresponding one or more virtual locations to different respective one or more virtual locations.
