    • Provided are computer program product, system, and method for assessing a backup image comprising a backup of a source computer system to recover to a target computer system. A point-in-time backup image is selected from a plurality of backup images taken of an image on the source computer system, wherein the selected backup is to be applied to the target computer system. A determination is made from a plurality of retention policies applicable to files included in the source computer system a most restrictive retention policy. A determination is made as to whether the selected backup image satisfies the most restrictive retention policy. A retention status of the backup image is set based on whether the determined version of the selected backup satisfies the most restrictive retention policy. The retention status is presented for use in determining whether to use the selected backup image.
    • 提供了用于评估备份图像的计算机程序产品,系统和方法,其包括源计算机系统的备份以恢复到目标计算机系统。 从源计算机系统上的图像拍摄的多个备份图像中选择时间点备份图像,其中所选备份被应用于目标计算机系统。 从适用于包含在源计算机系统中的文件的多个保留​​策略确定最严格的保留策略。 确定所选择的备份图像是否满足最严格的保留策略。 基于所选备份的确定版本是否满足最严格的保留策略,设置备份映像的保留状态。 提供保留状态用于确定是否使用所选的备份映像。

    • 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.
    • 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。

    • A system and method for relating files in a distributed data storage environment allows for positive identification of membership of a file within a group, even in a loosely coupled environment where files are not available for comparison in real time. In disclosed embodiments, base files of a client are stored on a server and are accompanied by tokens uniquely identifying the base files. The tokens are generated on the client and may be derived from the contents of the base file using a digital signature. Each file transmitted to the server is accompanied with a token. Incremental backups may be used, and may employ file differencing. Accordingly, sub-files related to the base files may be transmitted to the server for backup. The sub-files are related to their respective base files using the tokens and are cross-linked to the base files so that any sub-files can be retrieved together with the base file from which the sub-file was derived.
    • 用于在分布式数据存储环境中关联文件的系统和方法允许对组内的文件的成员资格进行肯定的识别,即使在文件不可用于实时比较的松耦合环境中。 在所公开的实施例中,客户端的基本文件被存储在服务器上,并且伴随着唯一地标识基本文件的令牌。 令牌在客户端上生成,并且可以使用数字签名从基础文件的内容导出。 发送到服务器的每个文件都附带一个令牌。 可以使用增量备份,并可能采用文件差异化。 因此,可以将与基本文件相关的子文件发送到服务器进行备份。 子文件与使用令牌的各自的基本文件相关,并与基本文件交链,以便可以将所有子文件与从其导出子文件的基本文件一起检索。
