Abstract
Capturing post-snapshot quiescence writes in an image backup. In one example embodiment, a method for capturing post-snapshot quiescence writes in an image backup may include taking a first snapshot of a source storage at a first point in time using a Volume Shadow Copy Service (VSS), identifying a first set of block positions of blocks that are allocated in the source storage at the first point in time, identifying a second set of block positions of blocks that are written to the first snapshot during post-snapshot quiescence of the first snapshot by the VSS or by one or more VSS writers, resulting in a first quiesced snapshot, calculating a third set of block positions by performing a Boolean OR operation on the first and second sets of block positions, and copying blocks in the third set of block positions from the first snapshot to a full image backup.
