Abstract
Head start population of an image backup. In one example embodiment, a method for head start population of an image backup may include tracking blocks that are modified in a source storage between a first point in time and a second point in time, head start copying a first portion of the modified blocks into the image backup prior to the second point in time and ceasing the tracking of the first portion of the modified blocks as being modified, activating a snapshot on the source storage at the second point in time where the snapshot represents a state of the source storage at the second point in time, and copying, subsequent to the second point in time, from the snapshot and into the image backup, a second portion of the modified blocks that were not yet copied into the image backup by the second point in time.
