Abstract:
A method for analyzing data corruption is disclosed. In one embodiment, such a method includes identifying a data set containing corrupted data. The method identifies a specific location within the data set containing the corrupted data and analyzes the specific location to determine if the corrupted data is contained therein. The method repeatedly performs the following until the corrupted data is no longer found within the specific location: revert to a previous version of the specific location by removing an incremental update to the specific location, and analyze the previous version of the specific location to determine if it contains the corrupted data. When a previous version of the specific location is found that no longer contains the corrupted data, the method determines a timestamp associated with the previous version and provides the timestamp to a user. A corresponding system and computer program product are also disclosed.
