摘要： A mechanism is provided which allows to de-duplicate encrypted data such that the de-duplication ratio for encrypted data is similar to the de-duplication ration of the corresponding un-encrypted data and the purpose of encryption is not obfuscated, i.e. only the originator of the data (the client) can decrypt—and hence read—the data. This is achieved by interwoven the de-duplication algorithm with the encryption algorithm in a way that the data are encrypted with a key that is generated from the unencrypted data. Afterwards, that key is itself encrypted with an encryption key being private to a particular client. Due to the fact that the private key is not effecting the encrypted data stream, it can still be de-duplicated efficiently.
摘要翻译：提供了一种机制，其允许对加密数据进行去重复，使得加密数据的重复数据删除率与相应的未加密数据的重复数据删除率相似，并且加密的目的不被模糊化，即只有发起者的数据（客户端）可以解密，从而读取数据。这是通过使用加密算法将重复数据删除算法与以非加密数据生成的密钥进行数据加密的方式实现的。之后，该密钥本身使用对特定客户端是私有的加密密钥进行加密。由于私钥不影响加密的数据流，因此仍然可以有效地解除复制。

摘要： The present invention provides for an enhanced method and system for assuring integrity of deduplicated data objects stored within a storage system. A digital signature of the data object is generated to determine if the data object reassembled from a deduplicated state is identical to its pre-deduplication state. In one embodiment, generating the object signature of a data object before deduplication comprises generating an object signature from intermediate hash values computed from a hash function operating on each data chunk within the data object, the hash function also used to determine duplicate data chunks. In an alternative embodiment, generating the object signature of a data object before deduplication comprises generating an object signature on a portion of each data chunk of the data object.

摘要： Provided are techniques for storing local versions of a data set. A first number that indicates how many local versions of the data set are to be stored in local storage given an amount of available local storage is received. It is determined whether a second number that indicates a total number of local versions of the data set that the local storage is capable of storing exceeds the first number. In response to determining that the second number exceeds the first number, the amount of local storage that is capable of storing the first number of local versions of the data set is used.

摘要： A method, system, and article to manage a backup procedure of one or more backup tasks in a computing system. A backup window within which the backup tasks are to be executed is defined, and the backup tasks within the backup window are scheduled. The process of the backup procedure is controlled during execution. The process of controlling the backup procedure includes calculating the prospective duration of all actually running and all future backup tasks, and cancelling low priority backup tasks in case a higher priority backup task is projected to continue beyond an end time (Tend) of the backup window.

摘要： In response to read and write requests for data blocks at logical storage locations, a block mapping device determines physical storage locations on the storage devices. Read requests switch over secondary storage devices to the active mode when they are in the passive mode. Write requests write data blocks only to the primary storage devices. Secondary storage devices that have not been accessed for a minimum activation time may be switched over from the active to the passive mode to save power consumption and cooling. Data migration and data recall policies control moving of data blocks between the primary and secondary storage devices and are primarily based on threshold values.
摘要翻译：响应于对逻辑存储位置的数据块的读取和写入请求，块映射设备确定存储设备上的物理存储位置。读取请求在二级存储设备处于被动模式时切换到活动模式。写入请求仅将数据块写入主存储设备。在最小启动时间内未访问的辅助存储设备可能会从主动模式切换到被动模式，以节省功耗和冷却。数据迁移和数据调用策略控制主存储设备和辅助存储设备之间数据块的移动，主要基于阈值。
