Zusammenfassung:A first snapshot of a volume is created at a first point in time. A first backup operation to backup the volume to a first backup image using the first snapshot is initiated. The first backup operation terminates before completion, e.g., due to a failure. A second snapshot of the volume representing the state of the volume at a second point in time is then created. The second snapshot is used by a second backup operation to resume backing up the volume to a second backup image. The first backup image is then merged with the second backup image.
