Are you sure you are comparing against the correct snapshot? If you use
dump -L, the snapshot is created, opened, and immediately unlinked,
then the open file is saved. After dump exits, the snapshot file is
pysically released.

Are you creating a snapshot manually? What commands do you use exactly?
