According to one embodiment of the present invention, a system analyzes data in response to detecting occurrence of an event, and includes a computer system including at least one processor. The system maps fields between the data and a fingerprint definition identifying relevant fields of the data to produce a fingerprint for the data. The data is deleted after occurrence of the event. The produced fingerprint is stored in a data repository, and retrieved in response to detection of the event occurrence after the data has been deleted. The system analyzes the retrieved fingerprint to evaluate an impact of the event on corresponding deleted data. Embodiments of the present invention further include a method and computer program product for analyzing data in response to detecting occurrence of an event in substantially the same manner described above.
