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.
摘要翻译：可以提供一种系统，方法和装置，以使数据对象能够从单实例数据对象存储中移除，从而确保只有已经从所有存储器中删除所有引用的数据对象已被删除。因此，可以保持存储的一致性和可靠性，同时允许真正需要删除的数据对象从商店中移除。

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。

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： A system and method for managing single instance storage. A computer system includes at least two backup servers, each backup server included in a single-instance storage pool. A first backup server conveys a first de-duplicated list identifying data segments from the first storage pool to a second backup server. The first backup server receives from the second backup server a second de-duplicated list identifying a subset of the data segments and conveys the subset of the data segments to the second backup server. In response to receiving the first list from the first backup server, the second backup server de-duplicates the first list against a second storage pool and conveys the second list to the first backup server. In response to receiving the subset of the data segments, the second backup server adds the received data segments to the second storage pool.

摘要： A system, method, and medium for detecting expired data in a data deduplicated storage system are disclosed. The system receives a request to insert a file into the deduplicated storage system. In response, the system determines a unique identifier for the file and stores the unique identifier in a list of unique identifiers associated with a data object that stores the file content. The system determines that the data object is not expired based at least in part on the identifier being present in the list of unique identifiers.
