  • Accumulating changes in a database management system by copying the data object to the image copy if the data object identifier of the data object is greater than the image identifier of the image copy
    Patent number: 6161109
    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.

    Patent number: 6119128
    Abstract: A method, apparatus, and article of manufacture for a computer implemented recovery system for restoring a database in a computer. The database contains objects and is stored on a primary data storage device connected to the computer. Objects of different types in the database are copied from the primary data storage device to a secondary data storage device. Modifications to the objects are logged in a log file. A recovery indicator is received that indicates that recovery of the objects in the database is required. The objects are copied from the secondary data storage device to the database on the primary data storage device. Modifications in the log file are applied to the copied objects during one pass through the log file.
