Abstract
A computer-implemented method may, at a first point in time, back up at least a portion of a data-storage entity to a first virtual-disk file. The computer-implemented method may capture, in a second virtual-disk file, at least one change made to data in the data-storage entity after the first point in time. The computer-implemented method may also create a parent-child relationship between the first virtual-disk file and the second virtual-disk file, with first virtual-disk file being a parent of the second virtual-disk file. The computer-implemented method may further copy data stored in the second virtual-disk file to the first virtual-disk file so that the first virtual-disk file includes the at least one change made to data in the data-storage entity after the first point in time. Various other methods, systems, and computer-readable media are also disclosed.
