    • The disclosed computer-implemented method for healing images in deduplication storage may include (1) detecting that a data segment stored within deduplication storage is corrupted by executing an algorithm on the data segment to generate a numerical identifier for the data segment and determining that the numerical identifier does not match a previously stored numerical identifier for the data segment, (2) checking, during a backup operation, whether a digital fingerprint of a data segment of an image being backed up matches a digital fingerprint of the corrupted data segment that was taken prior to corruption and that is already stored within the deduplication storage, and (3) appending the data segment from the image being backed up to a container that already contains the corrupted data segment rather than replacing the corrupted data segment. Various other methods, systems, and computer-readable media are also disclosed.
    • 所公开的用于在去重复存储装置中修复图像的计算机实现的方法可以包括(1)通过对数据片段执行算法来检测存储在去重复存储器内的数据片段是否被破坏,以生成用于 所述数据段并确定所述数字标识符与所述数据段的先前存储的数字标识符不匹配,(2)在备份操作期间检查正在备份的图像的数据段的数字指纹是否匹配数字指纹 损坏的数据段在腐败之前被采用并且已存储在重复数据删除存储器中,以及(3)将数据段从正在备份的映像附加到已经包含损坏的数据段的容器,而不是替换已损坏的 数据段。 还公开了各种其他方法,系统和计算机可读介质。
