ABSTRACT:
Disclosed is a method and apparatus for incrementally baking up a data volume. In one embodiment of the method, the data volume is created in a first memory, and a point-in-time (PIT) copy of the data volume is created at time T0. First data of the data volume is modified between times T0and T1, wherein time T1is subsequent to time T0. Second data of the data volume is copied to a second memory after time T1. The second data of the data volume is modified after the second data is copied to the second memory. Lastly, data of the PIT copy is overwritten with (1) the copy of the second data stored in the second memory and (2) the modified first data of the data volume.
