Abstract
A method, apparatus, and article of manufacture for a computer implemented image copying system for identifying modifications in a database in a computer. The database contains data objects and is stored on a primary data storage device connected to the computer. A data object identifier is generated for each data object as the data object is modified. An image identifier is generated for an image copy of the database when the image copy is updated, wherein the image copy is stored on a secondary data storage device. When one or more data objects are to be copied from the primary data storage device to the secondary data storage device, the data objects to be copied are determined by comparing the data object identifier of each data object to the image identifier.
