摘要： Various embodiments of a system and method for backing up a plurality of copies of a file are described. A first copy of the file may be owned by a first user, and a second copy of the file may be owned by a second user. The file is split into a plurality of segments, and each segment is encrypted with a respective segment key. Each encrypted segment is transmitted to and stored on a server computer system. De-duplication techniques are used to ensure that only a single instance of each encrypted segment is stored. The segment keys used to encrypt the file segments are also stored on the server computer system in an encrypted form. De-duplication techniques may be utilized so that only a single instance of the encrypted segment keys is stored.
摘要翻译：描述用于备份文件的多个副本的系统和方法的各种实施例。文件的第一副本可以由第一用户拥有，并且文件的第二副本可以由第二用户拥有。该文件被分割成多个段，并且每个段用相应的段密钥加密。每个加密的段被传送到并存储在服务器计算机系统上。重复数据删除技术用于确保只存储每个加密段的单个实例。用于加密文件段的段密钥也以加密形式存储在服务器计算机系统上。可以利用重复数据删除技术，使得仅存储加密的段密钥的单个实例。

摘要： A computer-implemented method for seeding a fingerprint cache for data deduplication associated with a single-instance-storage computing subsystem may comprise: 1) maintaining server-side fingerprint usage data for a plurality of fingerprints associated with data stored in the single-instance-storage computing subsystem and 2) building, based at least in part on the fingerprint usage data, a server-side fingerprint cache for use in client-side data deduplication, the server-side fingerprint cache comprising at least a subset of the plurality of fingerprints. The method may further comprise: 1) receiving a request for the server-side fingerprint cache from a client-side data deduplication computing subsystem and 2) transmitting data representative of the server-side fingerprint cache to the client-side data deduplication computing subsystem for use in client-side data deduplication associated with the single-instance-storage computing subsystem. Other exemplary fingerprint cache seeding and data deduplication methods, as well as corresponding exemplary systems and computer-readable media, are also disclosed.

摘要： There can be provided a system, method and apparatus to enable a data object to be removed from a single-instancing data object store in such a way as to ensure that only data objects to which all references have been removed are actually removed from the store. Thereby, consistency and reliability of storage can be maintained while allowing a data object which genuinely needs to be deleted to be removed from the store.

摘要： Various methods and systems for using adaptive data compression in a backup system are disclosed. One method involves detecting whether to compress a unit of storage that is to be backed up. The detecting involves attempting to compress a portion of the unit of storage. If the attempt to compress the portion of the unit of storage meets a specified compression performance threshold, i.e., if the unit of storage is compressible, the unit of storage is compressed. Otherwise the unit of storage is not compressed.

摘要： Analyzing backup objects maintained by a de-duplication server. A plurality of first objects may be maintained. Each first object may refer to second object(s) and each second object may refer back to at least one first object. For each respective first object, the respective first object may be analyzed to determine the one or more second objects referred to by the respective first object. Correspondingly, a command may be generated for each respective second object of the determined second object(s), thereby generating a plurality of commands. Each command may be used to verify that the respective second object refers back to the respective first object. The plurality of commands may be sorted into a disk access order. The commands may be used to verify that each second object refers back to first objects that refer to the second object.
摘要翻译：分析由重复数据删除服务器维护的备份对象。可以维护多个第一对象。每个第一对象可以指代第二对象，并且每个第二对象可以指向至少一个第一对象。对于每个相应的第一对象，可以分析相应的第一对象以确定由相应的第一对象引用的一个或多个第二对象。相应地，可以为确定的第二对象的每个相应的第二对象生成命令，从而生成多个命令。可以使用每个命令来验证相应的第二对象是否指向相应的第一对象。多个命令可以被分类成磁盘访问顺序。命令可用于验证每个第二对象是否引用指向第二对象的第一对象。
