Abstract

Various systems and methods are disclosed for applying incremental changes prior to initialization of a point-in-time copy. For example, one method involves identifying an incremental change to information stored on a primary device. The incremental change is identified subsequent to a first point in time. The incremental change is applied to a first target device, prior to completing initialization of a second target device. The initialization of the second target device initializes the second target device as a point-in-time copy of the primary device. The point-in-time copy of the primary device is a copy of the primary device at the first point in time.
