Abstract:
1. A system for performing data management operations, the system comprising: at least one target computer comprising computer hardware that communicates with at least one source computer to receive information about a source database stored on a first storage device; at least one second storage device in communication with the target computer; wherein the target computer replicates at least a portion of the source database to generate a target database on the second storage device, the target database existing in a dirty shutdown state at a first time; wherein the target computer copies at least a portion of the target database in the dirty shutdown state to create a first copy, the first copy stored in the dirty shutdown state; at a second time subsequent to creating the first copy, the target computer commits a plurality of data transactions to the target database that puts the target database into a clean shutdown state; wherein the target computer copies at least a portion of the target database in the clean shutdown state to create a second copy that includes data corresponding to the plurality of committed data transactions, wherein the second copy is stored in the clean shutdown state; and wherein the target computer reverts the target database in the clean shutdown state back to the dirty shutdown state based on differences between the first copy in the dirty shutdown state and the second copy in the clean shutdown state.
