Abstract
An apparatus and method for faster recovery of validated continuous data protection time images. In one embodiment of the method, an image validation process is initiated. In response, a first write transaction is generated for writing first new data to a first image of a data object that existed at prior time T1. The first new data is written to a first storage. Thereafter data contents of the first storage are copied to a first memory object. Finally, the first memory object is linked with the first image.
