Minimize damage caused by corruption of de-duplicated data
Abstract:
An embodiment for minimizing damage caused by corruption of de-duplicated data is disclosed. One embodiment counts the number of references to a data segment indexed by a de-duplication index. When a reference count for the data segment reaches a first threshold a duplicate of the data segment is generated. In addition, the duplicate of the data segment is also stored to minimize damage of the de-duplicated data caused by a corruption of the data segment.
Abstract(Chinese):

公开了一种用于最小化由重复数据的损坏引起的损坏的实施例。 一个实施例计算对由重复数据删除索引索引的数据段的引用的数量。 当数据段的引用计数达到第一阈值时，生成数据段的副本。 此外，还存储数据段的副本以最小化由数据段的损坏引起的去重复数据的损坏。
