Abstract:
Methods, systems, and physical computer storage media are now provided that improve backing up data sets. The method includes registering each database transaction to a central repository prior to starting the database transaction, each database transaction comprising a plurality of writes to be executed for a database application on a database, receiving a first signal indicating a start of a backup application on the database, and quiescing all database transactions registered to the central repository to thereby wait for all ongoing writes of the database transactions registered to the central repository to complete and to release control of the database to the database application
A method to store data is disclosed. The method supplies a computing system comprising a computing device, a first DASD in communication with the computing device, a second DASD in communication with the computing device, and a plurality of non-DASD data storage devices in communication with the computing device. The method migrates a dataset from the first DASD to the second DASD, and subsequently copies the dataset from the second DASD to one or more of the plurality on non-DASD data storage devices.
