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. |
