摘要： Data objects are replicated from a source storage managed by a source server to a target storage managed by a target server. A source list is built of objects at the source server to replicate to the target server. The target server is queried to obtain a target list of objects at the target server. A replication list is built indicating objects on the source list not included on the target list to transfer to the target server. For each object in the replication list, data for the object not already at the target storage is sent to the target server and metadata on the object is sent to the target server to cause the target server to include the metadata in an entry for the object in a target server replication database. An entry for the object is added to a source server replication database.

摘要： In one aspect of the present description, in connection with storing a first deduplicated data object in a primary storage pool, described operations include determining the duration of time that the first data object has resided in the primary storage pool, and comparing the determined duration of time to a predetermined time interval. In addition, described operations include, after the determined duration of time meets or exceeds the predetermined time interval, determining if the first data object has an extent referenced by another data object, and determining whether to move the first data object from the primary storage pool to a secondary storage pool as a function of whether the first data object has an extent referenced by another data object after the determined duration of time meets or exceeds the predetermined time interval. Other features and aspects may be realized, depending upon the particular application.

摘要： Provided are a computer program product, system, and method for encrypting data objects to back-up to a server. A client private key is intended to be maintained only by the client. A data object of chunks to store at the server is generated. A first portion of the chunks in the data object is encrypted with the client private key and the first portion of the chunks in the data object encrypted with the client private key are sent to the server to store. A second portion of the chunks in the data object not encrypted with the client private key are sent to the server to store.

摘要： Provided are a method, system, and article of manufacture, wherein a data structure corresponding to a set of client nodes selected from a plurality of client nodes is generated. Objects from the selected set of client nodes are stored in the data structure. A determination is made that an object corresponding to a client node of the selected set of client nodes has to be stored. An additional determination is made as to whether the object has already been stored in the data structure by any client node of the selected set of client nodes. The object is stored in the data structure, in response to determining that the object has not already been stored in the data structure by any client node of the selected set of client nodes.

摘要： A chunk index has information on chunks in a storage space referenced in objects in the storage space. The chunk index includes a reference count for each chunk indicating a number of objects in which the chunk is referenced and a reference measurement representing a level of data object references to the chunk. One chunk is selected to remove from the storage space based on a criteria applied to the reference measurements of chunks having reference counts indicating that the chunks are not referenced in one object in the storage space.

摘要： Various techniques for improving the performance of restoring deduplicated data files from a server to a client within a storage management system are disclosed. In one embodiment, a chunk index is maintained on the client that tracks the chunks remaining on the client for each data file that is stored to and restored from the storage server. When a specific file is selected for restore from the storage server to the client, the client determines if any local copies of this specific file's chunks are stored in files already existing on the client data store. The file is then reconstructed from a combination of these local copies of the file chunks and chunks retrieved from the storage server. Therefore, only chunks that are not stored or are inaccessible to the client are retrieved from the server, reducing server-side processing requirements and the bandwidth required for data restore operations.
摘要翻译：公开了用于提高从存储管理系统中的服务器向客户端恢复重复数据消除的数据文件的性能的各种技术。在一个实施例中，在客户机上维护块索引，其跟踪存储在存储服务器中并从存储服务器恢复的每个数据文件的客户端上剩余的块。当选择特定文件从存储服务器恢复到客户端时，客户端确定该特定文件块的任何本地副本是否存储在客户端数据存储上已存在的文件中。然后从文件块的这些本地副本和从存储服务器检索的块的组合重建文件。因此，仅从服务器检索不存储或无法访问客户端的块，从而减少了数据恢复操作所需的服务器端处理要求和带宽。

摘要： The various embodiments of the present invention include techniques for securing the use of data deduplication activities occurring in a source-deduplicating storage management system. These techniques are intended to prevent fake data backup, target data contamination, and data spoofing attacks initiated by a source. In one embodiment, one technique includes limiting chunk querying to authorized users. Another technique provides detection of attacks and unauthorized access to keys within the target system. Additional techniques include the combination of validating the existence of data from the source by validating the data chunk, validating a data sample of the data chunk, or validating a hash value of the data chunk. A further embodiment involves the use of policies to provide authorization levels for chunk sharing and linking within the target. These techniques separately and in combination provide a comprehensive strategy to avoid unauthorized access to data within the target storage system.
摘要翻译：本发明的各种实施例包括用于确保在源 - 重复数据删除存储管理系统中发生的重复数据删除活动的使用的技术。这些技术旨在防止由源发起的假数据备份，目标数据污染和数据欺骗攻击。在一个实施例中，一种技术包括限制对授权用户的块查询。另一种技术提供对目标系统内的攻击和未授权访问密钥的检测。附加技术包括通过验证数据块来验证来自源的数据的存在，验证数据块的数据样本或验证数据块的哈希值的组合。进一步的实施例涉及使用策略来为目标内的块共享和链接提供授权级别。这些技术分开并组合提供了一种全面的策略，以避免未经授权的访问目标存储系统中的数据。
