A method, computer program product and system for archiving data from an operational database. Data to be archived from the operational database may be stored either as received or transformed in a manner that allows the transformed archived data to be retrieved bit-for-bit identical to the original input received. Further, the data stored in the archive storage is read-only meaning that the data cannot be updated, deleted or modified. Further, backup copies of each of the storage units, which store the archived data, in the archive storage are created for disaster recovery purposes. Additionally, hash values are computed for each of the storage units in the archive storage which are used to detect unauthorized changes to the data stored in the storage units. In this manner, the authenticity of the data stored in the archive storage may be substantially guaranteed.
