38If the backing file is smaller than the snapshot, then the backing file will be
39resized to be the same size as the snapshot. If the snapshot is smaller than
40the backing file, the backing file will not be truncated. If you want the
41backing file to match the size of the smaller snapshot, you can safely truncate
42it yourself once the commit operation successfully completes.
