摘要： A computer-implemented method for creating reference-based synthetic backups. The method may include identifying a first set of references that identify data of a first backup. The first backup may represent at least a portion of a data set at a first time. The method may also include identifying a second set of references that identify data of a second backup. The second backup may represent changes made to the data set between the first time and a second time. The method may further include creating a synthetic backup that represents at least a portion of the data set at the second time by aggregating one or more references from the first set of references and one or more references from the second set of references. Various other methods, systems, and computer-readable media are also disclosed.

摘要： A computer-implemented method for deduplicating data is disclosed. The method may include identifying a request to transfer data from a client in a deduplication system to a server in the deduplication system. The method may also include determining, based at least in part on performance of the deduplication system, whether to deduplicate the data before transferring the data from the client to the server. The method may further include performing the following, the order of which is based on the determination: deduplicating the data and transferring the data from the client to the server. Various other methods, systems, and computer-readable media are also disclosed.
摘要翻译：公开了一种用于重复数据删除的计算机实现的方法。该方法可以包括识别将数据从重复数据删除系统中的客户端传送到重复数据删除系统中的服务器的请求。该方法还可以包括至少部分地基于重复数据删除系统的性能来确定在将数据从客户端传送到服务器之前是否重复数据删除。该方法还可以包括执行以下步骤，其顺序基于确定：重复数据删除并将数据从客户端传送到服务器。还公开了各种其它方法，系统和计算机可读介质。

摘要： Various embodiments of a computer system and methods are disclosed. In one embodiment, a computer system includes hosts coupled to a backup medium. The backup medium stores data segments and objects, each object referencing one or more segments. A second host conveys a write request to a first host identifying a data entity comprising segments referenced by a first object. The first host restores a copy of the data entity and creates a second object referencing the segments that were referenced by the first object in response to receiving the write request. The first host adds segment references to the second object in response to receiving a change that adds data to the copy or deletes a portion of a segment from the copy. The first host removes a segment reference from the second object if a change deletes all of a segment from the copy.
摘要翻译：公开了计算机系统和方法的各种实施例。在一个实施例中，计算机系统包括耦合到备份介质的主机。备份介质存储数据段和对象，每个对象引用一个或多个段。第二主机向第一主机传送标识包括由第一对象引用的段的数据实体的写入请求。第一主机恢复数据实体的副本，并创建引用由第一对象引用的响应于接收到写请求的段的第二对象。响应于接收到将数据添加到副本或从副本中删除段的一部分的改变，第一主机向第二对象添加段引用。如果更改从副本中删除所有段，则第一个主机将从第二个对象中删除段引用。

摘要： A system, method, and computer program product for backing up data from a backup source to a central repository using deduplication, where the data comprises source data segments is disclosed. A fingerprint cache comprising fingerprints of data segments stored in the central repository is received, where the data segments were previously backed up from the backup source. Source data fingerprints comprising fingerprints (e.g., hash values) of the source data segments are generated. The source data fingerprints are compared to the fingerprints in the fingerprint cache. The source data segments corresponding to fingerprints not in the fingerprint cache may not be currently stored in the central repository. After further queries to the central repository, one or more of the source data segments are sent to the central repository for storage responsive to comparison.
